[RocksDB] BackupableDB Summary: In this diff I present you BackupableDB v1. You can easily use it to backup your DB and it will do incremental snapshots for you. Let's first describe how you would use BackupableDB. It's inheriting StackableDB interface so you can easily construct it with your DB object -- it will add a method RollTheSnapshot() to the DB object. When you call RollTheSnapshot(), current snapshot of the DB will be stored in the backup dir. To restore, you can just call RestoreDBFromBackup() on a BackupableDB (which is a static method) and it will restore all files from the backup dir. In the next version, it will even support automatic backuping every X minutes. There are multiple things you can configure: 1. backup_env and db_env can be different, which is awesome because then you can easily backup to HDFS or wherever you feel like. 2. sync - if true, it *guarantees* backup consistency on machine reboot 3. number of snapshots to keep - this will keep last N snapshots around if you want, for some reason, be able to restore from an earlier snapshot. All the backuping is done in incremental fashion - if we already have 00010.sst, we will not copy it again. *IMPORTANT* -- This is based on assumption that 00010.sst never changes - two files named 00010.sst from the same DB will always be exactly the same. Is this true? I always copy manifest, current and log files. 4. You can decide if you want to flush the memtables before you backup, or you're fine with backing up the log files -- either way, you get a complete and consistent view of the database at a time of backup. 5. More things you can find in BackupableDBOptions Here is the directory structure I use: backup_dir/CURRENT_SNAPSHOT - just 4 bytes holding the latest snapshot 0, 1, 2, ... - files containing serialized version of each snapshot - containing a list of files files/*.sst - sst files shared between snapshots - if one snapshot references 00010.sst and another one needs to backup it from the DB, it will just reference the same file files/ 0/, 1/, 2/, ... - snapshot directories containing private snapshot files - current, manifest and log files All the files are ref counted and deleted immediatelly when they get out of scope. Some other stuff in this diff: 1. Added GetEnv() method to the DB. Discussed with @haobo and we agreed that it seems right thing to do. 2. Fixed StackableDB interface. The way it was set up before, I was not able to implement BackupableDB. Test Plan: I have a unittest, but please don't look at this yet. I just hacked it up to help me with debugging. I will write a lot of good tests and update the diff.

Implement autovector Summary: A vector that leverages pre-allocated stack-based array to achieve better performance for array with small amount of items. Test Plan: Added tests for both correctness and performance Here is the performance benchmark between vector and autovector Please note that in the test "Creation and Insertion Test", the test case were designed with the motivation described below: * no element inserted: internal array of std::vector may not really get initialize. * one element inserted: internal array of std::vector must have initialized. * kSize elements inserted. This shows the most time we'll spend if we keep everything in stack. * 2 * kSize elements inserted. The internal vector of autovector must have been initialized. Note: kSize is the capacity of autovector ===================================================== Creation and Insertion Test ===================================================== created 100000 vectors: each was inserted with 0 elements total time elapsed: 128000 (ns) created 100000 autovectors: each was inserted with 0 elements total time elapsed: 3641000 (ns) created 100000 VectorWithReserveSizes: each was inserted with 0 elements total time elapsed: 9896000 (ns) ----------------------------------- created 100000 vectors: each was inserted with 1 elements total time elapsed: 11089000 (ns) created 100000 autovectors: each was inserted with 1 elements total time elapsed: 5008000 (ns) created 100000 VectorWithReserveSizes: each was inserted with 1 elements total time elapsed: 24271000 (ns) ----------------------------------- created 100000 vectors: each was inserted with 4 elements total time elapsed: 39369000 (ns) created 100000 autovectors: each was inserted with 4 elements total time elapsed: 10121000 (ns) created 100000 VectorWithReserveSizes: each was inserted with 4 elements total time elapsed: 28473000 (ns) ----------------------------------- created 100000 vectors: each was inserted with 8 elements total time elapsed: 75013000 (ns) created 100000 autovectors: each was inserted with 8 elements total time elapsed: 18237000 (ns) created 100000 VectorWithReserveSizes: each was inserted with 8 elements total time elapsed: 42464000 (ns) ----------------------------------- created 100000 vectors: each was inserted with 16 elements total time elapsed: 102319000 (ns) created 100000 autovectors: each was inserted with 16 elements total time elapsed: 76724000 (ns) created 100000 VectorWithReserveSizes: each was inserted with 16 elements total time elapsed: 68285000 (ns) ----------------------------------- ===================================================== Sequence Access Test ===================================================== performed 100000 sequence access against vector size: 4 total time elapsed: 198000 (ns) performed 100000 sequence access against autovector size: 4 total time elapsed: 306000 (ns) ----------------------------------- performed 100000 sequence access against vector size: 8 total time elapsed: 565000 (ns) performed 100000 sequence access against autovector size: 8 total time elapsed: 512000 (ns) ----------------------------------- performed 100000 sequence access against vector size: 16 total time elapsed: 1076000 (ns) performed 100000 sequence access against autovector size: 16 total time elapsed: 1070000 (ns) ----------------------------------- Reviewers: dhruba, haobo, sdong, chip Reviewed By: dhruba CC: leveldb Differential Revision: https://reviews.facebook.net/D14655

[RocksDB] BackupableDB Summary: In this diff I present you BackupableDB v1. You can easily use it to backup your DB and it will do incremental snapshots for you. Let's first describe how you would use BackupableDB. It's inheriting StackableDB interface so you can easily construct it with your DB object -- it will add a method RollTheSnapshot() to the DB object. When you call RollTheSnapshot(), current snapshot of the DB will be stored in the backup dir. To restore, you can just call RestoreDBFromBackup() on a BackupableDB (which is a static method) and it will restore all files from the backup dir. In the next version, it will even support automatic backuping every X minutes. There are multiple things you can configure: 1. backup_env and db_env can be different, which is awesome because then you can easily backup to HDFS or wherever you feel like. 2. sync - if true, it *guarantees* backup consistency on machine reboot 3. number of snapshots to keep - this will keep last N snapshots around if you want, for some reason, be able to restore from an earlier snapshot. All the backuping is done in incremental fashion - if we already have 00010.sst, we will not copy it again. *IMPORTANT* -- This is based on assumption that 00010.sst never changes - two files named 00010.sst from the same DB will always be exactly the same. Is this true? I always copy manifest, current and log files. 4. You can decide if you want to flush the memtables before you backup, or you're fine with backing up the log files -- either way, you get a complete and consistent view of the database at a time of backup. 5. More things you can find in BackupableDBOptions Here is the directory structure I use: backup_dir/CURRENT_SNAPSHOT - just 4 bytes holding the latest snapshot 0, 1, 2, ... - files containing serialized version of each snapshot - containing a list of files files/*.sst - sst files shared between snapshots - if one snapshot references 00010.sst and another one needs to backup it from the DB, it will just reference the same file files/ 0/, 1/, 2/, ... - snapshot directories containing private snapshot files - current, manifest and log files All the files are ref counted and deleted immediatelly when they get out of scope. Some other stuff in this diff: 1. Added GetEnv() method to the DB. Discussed with @haobo and we agreed that it seems right thing to do. 2. Fixed StackableDB interface. The way it was set up before, I was not able to implement BackupableDB. Test Plan: I have a unittest, but please don't look at this yet. I just hacked it up to help me with debugging. I will write a lot of good tests and update the diff.

[RocksDB] Add stacktrace signal handler Summary: This diff provides the ability to print out a stacktrace when the process receives certain signals. Currently, we enable this for the following signals (program error related): SIGILL SIGSEGV SIGBUS SIGABRT Application simply #include "util/stack_trace.h" and call leveldb::InstallStackTraceHandler() during initialization, if signal handler is needed. It's not done automatically when openning db, because it's the application(process)'s responsibility to install signal handler and some applications might already have their own (like fbcode). Sample output: Received signal 11 (Segmentation fault) #0 0x408ff0 ./signal_test() [0x408ff0] /home/haobo/rocksdb/util/signal_test.cc:4 #1 0x40827d ./signal_test() [0x40827d] /home/haobo/rocksdb/util/signal_test.cc:24 #2 0x7f8bb183172e /usr/local/fbcode/gcc-4.7.1-glibc-2.14.1/lib/libc.so.6(__libc_start_main+0x10e) [0x7f8bb183172e] ??:0 #3 0x408ebc ./signal_test() [0x408ebc] /home/engshare/third-party/src/glibc/glibc-2.14.1/glibc-2.14.1/csu/../sysdeps/x86_64/elf/start.S:113 Segmentation fault (core dumped) For each frame, we print the raw pointer, the symbol provided by backtrace_symbols (still not good enough), and the source file/line. Note that address translation is done by directly shell out to addr2line. ??:0 means addr2line fails to do the translation. Hacky, but I think it's good for now.

[JNI] Add an initial benchmark for java binding for rocksdb. Summary: * Add a benchmark for java binding for rocksdb. The java benchmark is a complete rewrite based on the c++ db/db_bench.cc and the DbBenchmark in dain's java leveldb. * Support multithreading. * 'readseq' is currently not supported as it requires RocksDB Iterator. * usage: --benchmarks Comma-separated list of operations to run in the specified order Actual benchmarks: fillseq -- write N values in sequential key order in async mode fillrandom -- write N values in random key order in async mode fillbatch -- write N/1000 batch where each batch has 1000 values in random key order in sync mode fillsync -- write N/100 values in random key order in sync mode fill100K -- write N/1000 100K values in random order in async mode readseq -- read N times sequentially readrandom -- read N times in random order readhot -- read N times in random order from 1% section of DB Meta Operations: delete -- delete DB DEFAULT: [fillseq, readrandom, fillrandom] --compression_ratio Arrange to generate values that shrink to this fraction of their original size after compression DEFAULT: 0.5 --use_existing_db If true, do not destroy the existing database. If you set this flag and also specify a benchmark that wants a fresh database, that benchmark will fail. DEFAULT: false --num Number of key/values to place in database. DEFAULT: 1000000 --threads Number of concurrent threads to run. DEFAULT: 1 --reads Number of read operations to do. If negative, do --nums reads. --key_size The size of each key in bytes. DEFAULT: 16 --value_size The size of each value in bytes. DEFAULT: 100 --write_buffer_size Number of bytes to buffer in memtable before compacting (initialized to default value by 'main'.) DEFAULT: 4194304 --cache_size Number of bytes to use as a cache of uncompressed data. Negative means use default settings. DEFAULT: -1 --seed Seed base for random number generators. DEFAULT: 0 --db Use the db with the following name. DEFAULT: /tmp/rocksdbjni-bench * Add RocksDB.write().
