Summary:
Refactor WriteImpl() so when I plug-in the pipeline write code (which is
an alternative approach for WriteThread), some of the logic can be
reuse. I split out the following methods from WriteImpl():
* PreprocessWrite()
* HandleWALFull() (previous MaybeFlushColumnFamilies())
* HandleWriteBufferFull()
* WriteToWAL()
Also adding a constructor to WriteThread::Writer, and move WriteContext into db_impl.h.
No real logic change in this patch.

Summary:
auto_roll_logger_test relies on timing conditon that some operations finish within 1 seconds. This caused flaky tests. Move away from real timing and sleep and use fake time to verify the time-based rolling.

`uint` is nonstandard and not a built-in type on all compilers; replace it
with the always-valid `unsigned int`. I assume this went unnoticed because
it's inside an `#ifdef ROCKDB_JEMALLOC`.

Previously it always showed 0.0 for L0 write-amp because we were dividing by bytes read from non-output level. For L0, we should instead divide by bytes ingested to the DB. Note the numerator (bytes written to L0) includes flush bytes.

Summary:
Operations like Seek/Next/Prev sometimes take too long to complete when there are many internal keys to be skipped. Adding an option, max_skippable_internal_keys -- which could be used to set a threshold for the maximum number of keys that can be skipped, will help to address these cases where it is much better to fail a request (as incomplete) than to wait for a considerable time for the request to complete.
This feature -- to fail an iterator seek request as incomplete, is disabled by default when max_skippable_internal_keys = 0. It is enabled only when max_skippable_internal_keys > 0.
This feature is based on the discussion mentioned in the PR https://github.com/facebook/rocksdb/pull/1084.

Summary:
instead of thread_local
The cleanup path for the rocksdb database might not have the
thread_updater_local_cache_ pointer initialized because the thread
executing the cleanup is likely not a rocksdb thread. This results in a
memory leak detected by Valgrind. The cleanup code path should use the
thread_status_updater pointer obtained from the DB object instead of a
thread local one.

Added fifo benchmark to db_bench.
One thing i am not sure is that i am using CompactRange() instead of CompactFiles(). (may cause performance skew because CompactionRange() is not happening in current thread?) For CompactFiles(), for some reason FIFO compaction doesn't work as expected. More insight is welcomed. I guess FIFO compaction doesn't work with file names? igorcanadi

Summary:
I've added functions to the C API to support WriteBatchWithIndex as requested in #1833.
I've also added unit tests to c_test
I've implemented the WriteBatchWithIndex variation of every function available for regular WriteBatch. And added additional functions unique to WriteBatchWithIndex.
For now, the following is omitted:
1. The ability to create WriteBatchWithIndex's custom batch-only iterator as I'm not sure what its purpose is. It should be possible to add later if anyone wants it.
2. The ability to create the batch with a fallback comparator, since it appears to be unnecessary. I believe the column family comparator will be used for this, meaning those using a custom comparator can just use the column family variations.

Summary:
MemTableInserter default constructs Post processing info
std::map. However, on Windows with 2015 STL the default
constructed map still dynamically allocates one node
which shows up on a profiler and we loose ~40% throughput
on fillrandom benchmark.
Solution: declare a map as std::aligned storage and optionally
construct.
