Use new Insert and Lookup APIs in table reader to support secondary cache (#8315)
Summary: Secondary cache is implemented to achieve the secondary cache tier for block cache. New Insert and Lookup APIs are introduced in https://github.com/facebook/rocksdb/issues/8271 . To support and use the secondary cache in block based table reader, this PR introduces the corresponding callback functions that will be used in secondary cache, and update the Insert and Lookup APIs accordingly. benchmarking: ./db_bench --benchmarks="fillrandom" -num=1000000 -key_size=32 -value_size=256 -use_direct_io_for_flush_and_compaction=true -db=/tmp/rocks_t/db -partition_index_and_filters=true ./db_bench -db=/tmp/rocks_t/db -use_existing_db=true -benchmarks=readrandom -num=1000000 -key_size=32 -value_size=256 -use_direct_reads=true -cache_size=1073741824 -cache_numshardbits=5 -cache_index_and_filter_blocks=true -read_random_exp_range=17 -statistics -partition_index_and_filters=true -stats_dump_period_sec=30 -reads=50000000 master benchmarking results: readrandom : 3.923 micros/op 254881 ops/sec; 33.4 MB/s (23849796 of 50000000 found) rocksdb.db.get.micros P50 : 2.820992 P95 : 5.636716 P99 : 16.450553 P100 : 8396.000000 COUNT : 50000000 SUM : 179947064 Current PR benchmarking results readrandom : 4.083 micros/op 244925 ops/sec; 32.1 MB/s (23849796 of 50000000 found) rocksdb.db.get.micros P50 : 2.967687 P95 : 5.754916 P99 : 15.665912 P100 : 8213.000000 COUNT : 50000000 SUM : 187250053 About 3.8% throughput reduction.

Add table properties for number of entries added to filters (#8323)
Summary: With Ribbon filter work and possible variance in actual bits per key (or prefix; general term "entry") to achieve certain FP rates, I've received a request to be able to track actual bits per key in generated filters. This change adds a num_filter_entries table property, which can be combined with filter_size to get bits per key (entry). This can vary from num_entries in at least these ways: * Different versions of same key are only counted once in filters. * With prefix filters, several user keys map to the same filter entry. * A single filter can include both prefixes and user keys. Note that FilterBlockBuilder::NumAdded() didn't do anything useful except distinguish empty from non-empty.

Compare memtable insert and flush count (#8288)
Summary: When a memtable is flushed, it will validate number of entries it reads, and compare the number with how many entries inserted into memtable. This serves as one sanity c\ heck against memory corruption. This change will also allow more counters to be added in the future for better validation.

Use deleters to label cache entries and collect stats (#8297)
Summary:
This change gathers and publishes statistics about the
kinds of items in block cache. This is especially important for
profiling relative usage of cache by index vs. filter vs. data blocks.
It works by iterating over the cache during periodic stats dump
(InternalStats, stats_dump_period_sec) or on demand when
DB::Get(Map)Property(kBlockCacheEntryStats), except that for
efficiency and sharing among column families, saved data from
the last scan is used when the data is not considered too old.
The new information can be seen in info LOG, for example:
Block cache LRUCache@0x7fca62229330 capacity: 95.37 MB collections: 8 last_copies: 0 last_secs: 0.00178 secs_since: 0
Block cache entry stats(count,size,portion): DataBlock(7092,28.24 MB,29.6136%) FilterBlock(215,867.90 KB,0.888728%) FilterMetaBlock(2,5.31 KB,0.00544%) IndexBlock(217,180.11 KB,0.184432%) WriteBuffer(1,256.00 KB,0.262144%) Misc(1,0.00 KB,0%)

Solution detail - We need some way to flag what kind of blocks each
entry belongs to, preferably without changing the Cache API.
One of the complications is that Cache is a general interface that could
have other users that don't adhere to whichever convention we decide
on for keys and values. Or we would pay for an extra field in the Handle
that would only be used for this purpose.
This change uses a back-door approach, the deleter, to indicate the
"role" of a Cache entry (in addition to the value type, implicitly).
This has the added benefit of ensuring proper code origin whenever we
recognize a particular role for a cache entry; if the entry came from
some other part of the code, it will use an unrecognized deleter, which
we simply attribute to the "Misc" role.
An internal API makes for simple instantiation and automatic
registration of Cache deleters for a given value type and "role".
Another internal API, CacheEntryStatsCollector, solves the problem of
caching the results of a scan and sharing them, to ensure scans are
neither excessive nor redundant so as not to harm Cache performance.
Because code is added to BlocklikeTraits, it is pulled out of
block_based_table_reader.cc into its own file.
This is a reformulation of https://github.com/facebook/rocksdb/issues/8276, without the type checking option
(could still be added), and with actual stat gathering.

Allow cache_bench/db_bench to use a custom secondary cache (#8312)
Summary: This PR adds a ```-secondary_cache_uri``` option to the cache_bench and db_bench tools to allow the user to specify a custom secondary cache URI. The object registry is used to create an instance of the ```SecondaryCache``` object of the type specified in the URI. The main cache_bench code is packaged into a separate library, similar to db_bench. An example invocation of db_bench with a secondary cache URI - ```db_bench --env_uri=ws://ws.flash_sandbox.vll1_2/ -db=anand/nvm_cache_2 -use_existing_db=true -benchmarks=readrandom -num=30000000 -key_size=32 -value_size=256 -use_direct_reads=true -cache_size=67108864 -cache_index_and_filter_blocks=true -secondary_cache_uri='cachelibwrapper://filename=/home/anand76/nvm_cache/cache_file;size=2147483648;regionSize=16777216;admPolicy=random;admProbability=1.0;volatileSize=8388608;bktPower=20;lockPower=12' -partition_index_and_filters=true -duration=1800``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/8312 Reviewed By: zhichao-cao Differential Revision: D28544325 Pulled By: anand1976 fbshipit-source-id: 8f209b9af900c459dc42daa7a610d5f00176eeed |

Sync ingested files only if reopen is supported by the FS (#8296)
Summary: Some file systems (especially distributed FS) do not support reopening a file for writing. The ExternalSstFileIngestionJob calls ReopenWritableFile in order to sync the ingested file, which typically makes sense only on a local file system with a page cache (i.e Posix). So this change tries to sync the ingested file only if ReopenWritableFile doesn't return Status::NotSupported().

Fix MultiGet with PinnableSlices and Merge for WBWI (#8299)
Summary: The MultiGetFromBatchAndDB would fail if the PinnableSlice value being returned was pinned. This could happen if the value was retrieved from the DB (not memtable) or potentially if the values were reused (and a previous iteration returned a slice that was pinned). This change resets the pinnable value to clear it prior to attempting to use it, thereby eliminating the problem with the value already being pinned.

Make it possible to apply only a subrange of table property collectors (#8298)
Summary: This patch does two things: 1) Introduces some aliases in order to eliminate/prevent long-winded type names w/r/t the internal table property collectors (see e.g. `std::vector<std::unique_ptr<IntTblPropCollectorFactory>>`). 2) Makes it possible to apply only a subrange of table property collectors during table building by turning `TableBuilderOptions::int_tbl_prop_collector_factories` from a pointer to a `vector` into a range (i.e. a pair of iterators). Rationale: I plan to introduce a BlobDB related table property collector, which should only be applied during table creation if blob storage is enabled at the moment (which can be changed dynamically). This change will make it possible to include/ exclude the BlobDB related collector as needed without having to introduce a second `vector` of collectors in `ColumnFamilyData` with pretty much the same contents.

Initial support for secondary cache in LRUCache (#8271)
Summary: Defined the abstract interface for a secondary cache in include/rocksdb/secondary_cache.h, and updated LRUCacheOptions to take a std::shared_ptr<SecondaryCache>. An item is initially inserted into the LRU (primary) cache. When it ages out and evicted from memory, its inserted into the secondary cache. On a LRU cache miss and successful lookup in the secondary cache, the item is promoted to the LRU cache. Only support synchronous lookup currently. The secondary cache would be used to implement a persistent (flash cache) or compressed cache. Tests: Results from cache_bench and db_bench don't show any regression due to these changes. cache_bench results before and after this change - Command ```./cache_bench -ops_per_thread=10000000 -threads=1``` Before ```Complete in 40.688 s; QPS = 245774``` ```Complete in 40.486 s; QPS = 246996``` ```Complete in 42.019 s; QPS = 237989``` After ```Complete in 40.672 s; QPS = 245869``` ```Complete in 44.622 s; QPS = 224107``` ```Complete in 42.445 s; QPS = 235599``` db_bench results before this change, and with this change + https://github.com/facebook/rocksdb/issues/8213 and https://github.com/facebook/rocksdb/issues/8191 - Commands ```./db_bench --benchmarks="fillseq,compact" -num=30000000 -key_size=32 -value_size=256 -use_direct_io_for_flush_and_compaction=true -db=/home/anand76/nvm_cache/db -partition_index_and_filters=true``` ```./db_bench -db=/home/anand76/nvm_cache/db -use_existing_db=true -benchmarks=readrandom -num=30000000 -key_size=32 -value_size=256 -use_direct_reads=true -cache_size=1073741824 -cache_numshardbits=6 -cache_index_and_filter_blocks=true -read_random_exp_range=17 -statistics -partition_index_and_filters=true -threads=16 -duration=300``` Before ``` DB path: [/home/anand76/nvm_cache/db] readrandom : 80.702 micros/op 198104 ops/sec; 54.4 MB/s (3708999 of 3708999 found) ``` ``` DB path: [/home/anand76/nvm_cache/db] readrandom : 87.124 micros/op 183625 ops/sec; 50.4 MB/s (3439999 of 3439999 found) ``` After ``` DB path: [/home/anand76/nvm_cache/db] readrandom : 77.653 micros/op 206025 ops/sec; 56.6 MB/s (3866999 of 3866999 found) ``` ``` DB path: [/home/anand76/nvm_cache/db] readrandom : 84.962 micros/op 188299 ops/sec; 51.7 MB/s (3535999 of 3535999 found) ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/8271 Reviewed By: zhichao-cao Differential Revision: D28357511 Pulled By: anand1976 fbshipit-source-id: d1cfa236f00e649a18c53328be10a8062a4b6da2 |

New Cache API for gathering statistics (#8225)
Summary: Adds a new Cache::ApplyToAllEntries API that we expect to use (in follow-up PRs) for efficiently gathering block cache statistics. Notable features vs. old ApplyToAllCacheEntries: * Includes key and deleter (in addition to value and charge). We could have passed in a Handle but then more virtual function calls would be needed to get the "fields" of each entry. We expect to use the 'deleter' to identify the origin of entries, perhaps even more. * Heavily tuned to minimize latency impact on operating cache. It does this by iterating over small sections of each cache shard while cycling through the shards. * Supports tuning roughly how many entries to operate on for each lock acquire and release, to control the impact on the latency of other operations without excessive lock acquire & release. The right balance can depend on the cost of the callback. Good default seems to be around 256. * There should be no need to disable thread safety. (I would expect uncontended locks to be sufficiently fast.) I have enhanced cache_bench to validate this approach: * Reports a histogram of ns per operation, so we can look at the ditribution of times, not just throughput (average). * Can add a thread for simulated "gather stats" which calls ApplyToAllEntries at a specified interval. We also generate a histogram of time to run ApplyToAllEntries. To make the iteration over some entries of each shard work as cleanly as possible, even with resize between next set of entries, I have re-arranged which hash bits are used for sharding and which for indexing within a shard. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8225 Test Plan: A couple of unit tests are added, but primary validation is manual, as the primary risk is to performance. The primary validation is using cache_bench to ensure that neither the minor hashing changes nor the simulated stats gathering significantly impact QPS or latency distribution. Note that adding op latency histogram seriously impacts the benchmark QPS, so for a fair baseline, we need the cache_bench changes (except remove simulated stat gathering to make it compile). In short, we don't see any reproducible difference in ops/sec or op latency unless we are gathering stats nearly continuously. Test uses 10GB block cache with 8KB values to be somewhat realistic in the number of items to iterate over. Baseline typical output: ``` Complete in 92.017 s; Rough parallel ops/sec = 869401 Thread ops/sec = 54662 Operation latency (ns): Count: 80000000 Average: 11223.9494 StdDev: 29.61 Min: 0 Median: 7759.3973 Max: 9620500 Percentiles: P50: 7759.40 P75: 14190.73 P99: 46922.75 P99.9: 77509.84 P99.99: 217030.58 ------------------------------------------------------ [ 0, 1 ] 68 0.000% 0.000% ( 2900, 4400 ] 89 0.000% 0.000% ( 4400, 6600 ] 33630240 42.038% 42.038% ######## ( 6600, 9900 ] 18129842 22.662% 64.700% ##### ( 9900, 14000 ] 7877533 9.847% 74.547% ## ( 14000, 22000 ] 15193238 18.992% 93.539% #### ( 22000, 33000 ] 3037061 3.796% 97.335% # ( 33000, 50000 ] 1626316 2.033% 99.368% ( 50000, 75000 ] 421532 0.527% 99.895% ( 75000, 110000 ] 56910 0.071% 99.966% ( 110000, 170000 ] 16134 0.020% 99.986% ( 170000, 250000 ] 5166 0.006% 99.993% ( 250000, 380000 ] 3017 0.004% 99.996% ( 380000, 570000 ] 1337 0.002% 99.998% ( 570000, 860000 ] 805 0.001% 99.999% ( 860000, 1200000 ] 319 0.000% 100.000% ( 1200000, 1900000 ] 231 0.000% 100.000% ( 1900000, 2900000 ] 100 0.000% 100.000% ( 2900000, 4300000 ] 39 0.000% 100.000% ( 4300000, 6500000 ] 16 0.000% 100.000% ( 6500000, 9800000 ] 7 0.000% 100.000% ``` New, gather_stats=false.

Add ObjectRegistry to ConfigOptions (#8166)
Summary: This change enables a couple of things: - Different ConfigOptions can have different registry/factory associated with it, thereby allowing things like a "Test" ConfigOptions versus a "Production" - The ObjectRegistry is created fewer times and can be re-used The ConfigOptions can also be initialized/constructed from a DBOptions, in which case it will grab some of its settings (Env, Logger) from the DBOptions.

Add Merge Operator support to WriteBatchWithIndex (#8135)
Summary:
The WBWI has two differing modes of operation dependent on the value
of the constructor parameter `overwrite_key`.
Currently, regardless of the parameter, neither mode performs as
expected when using Merge. This PR remedies this by correctly invoking
the appropriate Merge Operator before returning results from the WBWI.
Examples of issues that exist which are solved by this PR:
## Example 1 with `overwrite_key=false`
Currently, from an empty database, the following sequence:
```
Put('k1', 'v1')
Merge('k1', 'v2')
Get('k1')
```
Incorrectly yields `v2`, that is to say that the Merge behaves like a Put.
## Example 2 with o`verwrite_key=true`
Currently, from an empty database, the following sequence:
```
Put('k1', 'v1')
Merge('k1', 'v2')
Get('k1')
```
Incorrectly yields `ERROR: kMergeInProgress`.
## Example 3 with `overwrite_key=false`
Currently, with a database containing `('k1' -> 'v1')`, the following sequence:
```
Merge('k1', 'v2')
GetFromBatchAndDB('k1')
```
Incorrectly yields `v1,v2`
## Example 4 with `overwrite_key=true`
Currently, with a database containing `('k1' -> 'v1')`, the following sequence:
```
Merge('k1', 'v1')
GetFromBatchAndDB('k1')
```
Incorrectly yields `ERROR: kMergeInProgress`.
## Example 5 with `overwrite_key=false`
Currently, from an empty database, the following sequence:
```
Put('k1', 'v1')
Merge('k1', 'v2')
GetFromBatchAndDB('k1')
```
Incorrectly yields `v1,v2`
## Example 6 with `overwrite_key=true`
Currently, from an empty database, `('k1' -> 'v1')`, the following sequence:
```
Put('k1', 'v1')
Merge('k1', 'v2')
GetFromBatchAndDB('k1')
```
Incorrectly yields `ERROR: kMergeInProgress`.

Deprecate obsolete "backupable db" from public APIs (#8274)
Summary: An early design of BackupEngine used stackable DB, so I guess a DB had to opt-in to being backupable. Unfortunately the naming of that obsolete design still infects our public API and implementation. This change fixes the public API, with a deprecated backward-compatibility header. `BackupableDBOptions` is renamed to `BackupEngineOptions` (copy-replace in the public header) and backup_engine.h replaces backupable_db.h (present for backward compatibility). The only other change in backupable_db.h -> backup_engine.h is cleaning up headers. Later changes will fix the internal implementation. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8274 Test Plan: The internal implementation of BackupEngine uses the name BackupEngineOptions, while the unit tests use the old name BackupableDBOptions. This gives me confidence that both still work. Reviewed By: mrambacher Differential Revision: D28259471 Pulled By: pdillinger fbshipit-source-id: a25dbe327b9772143488e7bb0ec7139ee42d0613 |

Cap automatic arena block size to 1 MB (#7907)
Summary: Larger arena block size does provide the benefit of reducing allocation overhead, however it may cause other troubles. For example, allocator is more likely not to allocate them to physical memory and trigger page fault. Weighing the risk, we cap the arena block size to 1MB.

Permit stdout "fail"/"error" in whitebox crash test (#8272)
Summary: In https://github.com/facebook/rocksdb/issues/8268, the `db_stress` stdout began containing both the strings "fail" and "error" (case-insensitive). The whitebox crash test failed upon seeing either of those strings. I checked that all other occurrences of "fail" and "error" (case-insensitive) that `db_stress` produces are printed to `stderr`. So this PR separates the handling of `db_stress`'s stdout and stderr, and only fails when one those bad strings are found in stderr. The downside of this PR is `db_stress`'s original interleaving of stdout/stderr is not preserved in `db_crashtest.py`'s output.

db_stress: wait for compaction to finish after open with failure injection (#8270)
Summary: When injecting in DB open, error can happen in background threads, causing DB open succeed, but DB is soon made read-only and subsequence writes will fail, which is not expected.

Refactor kill point (#8241)

The intention was to drop unflushed data before killing to simulate some job, and I tried to a pointer to fault ingestion fs to the killing class, but it ended up with harder than I thought.

Make ImmutableOptions struct that inherits from ImmutableCFOptions and ImmutableDBOptions (#8262)
Summary: The ImmutableCFOptions contained a bunch of fields that belonged to the ImmutableDBOptions. This change cleans that up by introducing an ImmutableOptions struct. Following the pattern of Options struct, this class inherits from the DB and CFOption structs (of the Immutable form). Only one structural change (the ImmutableCFOptions::fs was changed to a shared_ptr from a raw one) is in this PR. All of the other changes involve moving the member variables from the ImmutableCFOptions into the ImmutableOptions and changing member variables or function parameters as required for compilation purposes. Follow-on PRs may do a further clean-up of the code, such as renaming variables (such as "ImmutableOptions cf_options") and potentially eliminating un-needed function parameters (there is no longer a need to pass both an ImmutableDBOptions and an ImmutableOptions to a function).

Fix use-after-free threading bug in ClockCache (#8261)
Summary: In testing for https://github.com/facebook/rocksdb/issues/8225 I found cache_bench would crash with -use_clock_cache, as well as db_bench -use_clock_cache, but not single-threaded. Smaller cache size hits failure much faster. ASAN reported the failuer as calling malloc_usable_size on the `key` pointer of a ClockCache handle after it was reportedly freed. On detailed inspection I found this bad sequence of operations for a cache entry: state=InCache=1,refs=1 [thread 1] Start ClockCacheShard::Unref (from Release, no mutex) [thread 1] Decrement ref count state=InCache=1,refs=0 [thread 1] Suspend before CalcTotalCharge (no mutex) [thread 2] Start UnsetInCache (from Insert, mutex held) [thread 2] clear InCache bit state=InCache=0,refs=0 [thread 2] Calls RecycleHandle (based on pre-updated state) [thread 2] Returns to Insert which calls Cleanup which deletes `key` [thread 1] Resume ClockCacheShard::Unref [thread 1] Read `key` in CalcTotalCharge To fix this, I've added a field to the handle to store the metadata charge so that we can efficiently remember everything we need from the handle in Unref. We must not read from the handle again if we decrement the count to zero with InCache=1, which means we don't own the entry and someone else could eject/overwrite it immediately. Note before this change, on amd64 sizeof(Handle) == 56 even though there are only 48 bytes of data. Grouping together the uint32_t fields would cut it down to 48, but I've added another uint32_t, which takes it back up to 56. Not a big deal. Also fixed DisownData to cooperate with ASAN as in LRUCache.

Fix ConcurrentTaskLimiter token release for shutdown (#8253)
Summary:
Previously the shutdown process did not properly wait for all
`compaction_thread_limiter` tokens to be released before proceeding to
delete the DB's C++ objects. When this happened, we saw tests like
"DBCompactionTest.CompactionLimiter" flake with the following error:
```
virtual
rocksdb::ConcurrentTaskLimiterImpl::~ConcurrentTaskLimiterImpl():
Assertion `outstanding_tasks_ == 0' failed.
```
There is a case where a token can still be alive even after the shutdown
process has waited for BG work to complete. In particular, this happens
because the shutdown process only waits for flush/compaction scheduled/unscheduled counters to all
reach zero. These counters are decremented in `BackgroundCallCompaction()`
functions. However, tokens are released in `BGWork*Compaction()` functions, which
actually wrap the `BackgroundCallCompaction()` function.
A simple sleep could repro the race condition:

Deflake DBTest.L0L1L2AndUpHitCounter (#8259)
Summary: Previously we saw flakes on platforms like arm on CircleCI, such as the following: ``` Note: Google Test filter = DBTest.L0L1L2AndUpHitCounter [==========] Running 1 test from 1 test case. [----------] Global test environment set-up. [----------] 1 test from DBTest [ RUN ] DBTest.L0L1L2AndUpHitCounter db/db_test.cc:5345: Failure Expected: (TestGetTickerCount(options, GET_HIT_L0)) > (100), actual: 30 vs 100 [ FAILED ] DBTest.L0L1L2AndUpHitCounter (150 ms) [----------] 1 test from DBTest (150 ms total) [----------] Global test environment tear-down [==========] 1 test from 1 test case ran. (150 ms total) [ PASSED ] 0 tests. [ FAILED ] 1 test, listed below: [ FAILED ] DBTest.L0L1L2AndUpHitCounter ``` The test was totally non-deterministic, e.g., flush/compaction timing would affect how many files on each level. Furthermore, it depended heavily on platform-specific details, e.g., by having a 32KB memtable, it could become full with a very different number of entries depending on the platform. This PR rewrites the test to build a deterministic LSM with one file per level.

Hint temperature of bottommost level files to FileSystem (#8222)
Summary: As the first part of the effort of having placing different files on different storage types, this change introduces several things: (1) An experimental interface in FileSystem that specify temperature to a new file created. (2) A test FileSystemWrapper, SimulatedHybridFileSystem, that simulates HDD for a file of "warm" temperature. (3) A simple experimental feature ColumnFamilyOptions.bottommost_temperature. RocksDB would pass this value to FileSystem when creating any bottommost file. (4) A db_bench parameter that applies the (2) and (3) to db_bench. The motivation of the change is to introduce minimal changes that allow us to evolve tiered storage development. Pull Request resolved: https://github.com/facebook/rocksdb/pull/8222 Test Plan: ./db_bench --benchmarks=fillrandom --write_buffer_size=2000000 -max_bytes_for_level_base=20000000 -level_compaction_dynamic_level_bytes --reads=100 -compaction_readahead_size=20000000 --reads=100000 -num=10000000 followed by ./db_bench --benchmarks=readrandom,stats --write_buffer_size=2000000 -max_bytes_for_level_base=20000000 -simulate_hybrid_fs_file=/tmp/warm_file_list -level_compaction_dynamic_level_bytes -compaction_readahead_size=20000000 --reads=500 --threads=16 -use_existing_db --num=10000000 and see results as expected.

Add more LSM info to FilterBuildingContext (#8246)
Summary: Add `num_levels`, `is_bottommost`, and table file creation `reason` to `FilterBuildingContext`, in anticipation of more powerful Bloom-like filter support. To support this, added `is_bottommost` and `reason` to `TableBuilderOptions`, which allowed removing `reason` parameter from `rocksdb::BuildTable`. I attempted to remove `skip_filters` from `TableBuilderOptions`, because filter construction decisions should arise from options, not one-off parameters. I could not completely remove it because the public API for SstFileWriter takes a `skip_filters` parameter, and translating this into an option change would mean awkwardly replacing the table_factory if it is BlockBasedTableFactory with new filter_policy=nullptr option. I marked this public skip_filters option as deprecated because of this oddity. (skip_filters on the read side probably makes sense.) At least `skip_filters` is now largely hidden for users of `TableBuilderOptions` and is no longer used for implementing the optimize_filters_for_hits option. Bringing the logic for that option closer to handling of FilterBuildingContext makes it more obvious that hese two are using the same notion of "bottommost." (Planned: configuration options for Bloom-like filters that generalize `optimize_filters_for_hits`) Recommended follow-up: Try to get away from "bottommost level" naming of things, which is inaccurate (see VersionStorageInfo::RangeMightExistAfterSortedRun), and move to "bottommost run" or just "bottommost." Pull Request resolved: https://github.com/facebook/rocksdb/pull/8246 Test Plan: extended an existing unit test to exercise and check various filter building contexts. Also, existing tests for optimize_filters_for_hits validate some of the "bottommost" handling, which is now closely connected to FilterBuildingContext::is_bottommost through TableBuilderOptions::is_bottommost Reviewed By: mrambacher Differential Revision: D28099346 Pulled By: pdillinger fbshipit-source-id: 2c1072e29c24d4ac404c761a7b7663292372600a |

Refactor: use TableBuilderOptions to reduce parameter lists (#8240)
Summary: Greatly reduced the not-quite-copy-paste giant parameter lists of rocksdb::NewTableBuilder, rocksdb::BuildTable, BlockBasedTableBuilder::Rep ctor, and BlockBasedTableBuilder ctor. Moved weird separate parameter `uint32_t column_family_id` of TableFactory::NewTableBuilder into TableBuilderOptions. Re-ordered parameters to TableBuilderOptions ctor, so that `uint64_t target_file_size` is not randomly placed between uint64_t timestamps (was easy to mix up). Replaced a couple of fields of BlockBasedTableBuilder::Rep with a FilterBuildingContext. The motivation for this change is making it easier to pass along more data into new fields in FilterBuildingContext (follow-up PR).

Improve BlockPrefetcher to prefetch only for sequential scans (#7394)
Summary: BlockPrefetcher is used by iterators to prefetch data if they anticipate more data to be used in future and this is valid for forward sequential scans. But BlockPrefetcher tracks only num_file_reads_ and not if reads are sequential. This presents problem for MultiGet with large number of keys when it reseeks index iterator and data block. FilePrefetchBuffer can end up doing large readahead for reseeks as readahead size increases exponentially once readahead is enabled. Same issue is with BlockBasedTableIterator. Add previous length and offset read as well in BlockPrefetcher (creates FilePrefetchBuffer) and FilePrefetchBuffer (does prefetching of data) to determine if reads are sequential and then prefetch. Update the last block read after cache hit to take reads from cache also in account.
