Summary: * Adds support for plain table filter. This is not critical right now, but does add a -impl flag that will be useful for new filter implementations initially targeted at block-based table (and maybe later ported to plain table) * Better mixing of inside vs. outside queries, for more realism * A -best_case option handy for implementation tuning inner loop * Option for whether to include hashing time in dry run / net timings No modifications to production code, just filter_bench.

Summary: A bug occasionally shows up in crash test, and https://github.com/facebook/rocksdb/issues/5851 reproduces it. The bug can surface in the following way. 1. Database has multiple column families. 2. Between one DB restart, the last log file is corrupted in the middle (not the tail) 3. During restart, DB crashes between flushing between two column families. Then DB will fail to be opened again with error "SST file is ahead of WALs". Solution is to update the log number associated with each column family altogether after flushing all column families' memtables. The version edits should be written to a new MANIFEST. Only after writing to all these version edits succeed does RocksDB (atomically) points the CURRENT file to the new MANIFEST. Test plan (on devserver): ``` $make all && make check ``` Specifically ``` $make db_test2 $./db_test2 --gtest_filter=DBTest2.CrashInRecoveryMultipleCF ``` Also checked for compatibility as follows. Use this branch, run DBTest2.CrashInRecoveryMultipleCF and preserve the db directory. Then checkout 5.4, build ldb, and dump the MANIFEST.

Summary: - Updated our included xxhash implementation to version 0.7.2 (== the latest dev version as of 2019-10-09). - Using XXH_NAMESPACE (like other fb projects) to avoid potential name collisions. - Added fastrange64, and unit tests for it and fastrange32. These are faster alternatives to hash % range. - Use preview version of XXH3 instead of MurmurHash64A for NPHash64 -- Had to update cache_test to increase probability of passing for any given hash function. - Use fastrange64 instead of % with uses of NPHash64 -- Had to fix WritePreparedTransactionTest.CommitOfDelayedPrepared to avoid deadlock apparently caused by new hash collision. - Set default seed for NPHash64 because specifying a seed rarely makes sense for it. - Removed unnecessary include xxhash.h in a popular .h file - Rename preview version of XXH3 to XXH3p for clarity and to ease backward compatibility in case final version of XXH3 is integrated. Relying on existing unit tests for NPHash64-related changes. Each new implementation of fastrange64 passed unit tests when manipulating my local build to select it. I haven't done any integration performance tests, but I consider the improved performance of the pieces being swapped in to be well established.

Summary: The parts that are used to implement FilterPolicy / NewBloomFilterPolicy and not used other than for the block-based table should be consolidated under table/block_based/filter_policy*. I don't foresee sharing these APIs with e.g. the Plain Table because they don't expose hashes for reuse in indexing. This change is step 1 of 2: (a) mv table/full_filter_bits_builder.h to table/block_based/filter_policy_internal.h which I expect to expand soon to internally reveal more implementation details for testing. (b) consolidate eventual contents of table/block_based/filter_policy.cc in util/bloom.cc, which has the most elaborate revision history (see step 2 ...) Step 2 soon to follow: mv util/bloom.cc table/block_based/filter_policy.cc This gets its own PR so that git has the best chance of following the rename for blame purposes.

Summary: The first version of filter_bench has selectable key size but that size does not vary throughout a test run. This artificially favors "branchy" hash functions like the existing BloomHash, MurmurHash1, probably because of optimal return for branch prediction. This change primarily varies those key sizes from -2 to +2 bytes vs. the average selected size. We also set the default key size at 24 to better reflect our best guess of typical key size. But steadily random key sizes may not be realistic either. So this change introduces a new filter_bench option: -vary_key_size_log2_interval=n where the same key size is used 2^n times and then changes to another size. I've set the default at 5 (32 times same size) as a compromise between deployments with rather consistent vs. rather variable key sizes. On my Skylake system, the performance boost to MurmurHash1 largely lies between n=10 and n=15. Also added -vary_key_alignment (bool, now default=true), though this doesn't currently seem to matter in hash functions under consideration. This change also does a "dry run" for each testing scenario, to improve the accuracy of those numbers, as there was more difference between scenarios than expected. Subtracting gross test run times from dry run times is now also embedded in the output, because these "net" times are generally the most useful.

Summary: For more information on the original problem see this [link](https://github.com/facebook/rocksdb/issues/3977). This change adds two new tests. They are identical other than one uses range tombstones and the other does not. Each test generates sub files at L2 which overlap with keys L3. The test that uses range tombstones generates a single file at L2. This single file will generate a very large range overlap that will in turn create excessively large compaction. 1: T001 - T005 2: 000 - 005 In contrast, the test that uses key ranges generates 3 files at L2. As a single file is compacted at a time, those 3 files will generate less work per compaction iteration. 1: 001 - 002 1: 003 - 004 1: 005 2: 000 - 005 Pull Request resolved: https://github.com/facebook/rocksdb/pull/5956 Differential Revision: D18071631 Pulled By: dlambrig fbshipit-source-id: 12abae75fb3e0b022d228c6371698aa5e53385df

Summary: Several error paths in opening of a plain table would leak memory. PR https://github.com/facebook/rocksdb/issues/5940 opened the leak to one more error path, which happens to have been (mistakenly) exercised by CuckooTableDBTest.AdaptiveTable. That test has been fixed, and the exercising of plain table error cases (more than before) has been added as BadOptions1 and BadOptions2 to PlainTableDBTest. This effectively moved the memory leak to plain_table_db_test. Also here is a cheap fix for the memory leak, without (yet?) changing the signature of ReadTableProperties. This fixes ASAN on unit tests.

Summary: Amongst other things, PR https://github.com/facebook/rocksdb/issues/5504 refactored the filter block readers so that only the filter block contents are stored in the block cache (as opposed to the earlier design where the cache stored the filter block reader itself, leading to potentially dangling pointers and concurrency bugs). However, this change introduced a performance hit since with the new code, the metadata fields are re-parsed upon every access. This patch reunites the block contents with the filter bits reader to eliminate this overhead; since this is still a self-contained pure data object, it is safe to store it in the cache. (Note: this is similar to how the zstd digest is handled.)

Summary: FullFilterBitsReader, after creating in BloomFilterPolicy, was responsible for decoding metadata bits. This meant that FullFilterBitsReader::MayMatch had some metadata checks in order to implement "always true" or "always false" functionality in the case of inconsistent or trivial metadata. This made for ugly mixing-of-concerns code and probably had some runtime cost. It also didn't really support plugging in alternative filter implementations with extensions to the existing metadata schema. BloomFilterPolicy::GetFilterBitsReader is now (exclusively) responsible for decoding filter metadata bits and constructing appropriate instances deriving from FilterBitsReader. "Always false" and "always true" derived classes allow FullFilterBitsReader not to be concerned with handling of trivial or inconsistent metadata. This also makes for easy expansion to alternative filter implementations in new, alternative derived classes. This change makes calls to FilterBitsReader::MayMatch *necessarily* virtual because there's now more than one built-in implementation. Compared with the previous implementation's extra 'if' checks in MayMatch, there's no consistent performance difference, measured by (an older revision of) filter_bench (differences here seem to be within noise): Inside queries... - Dry run (407) ns/op: 35.9996 + Dry run (407) ns/op: 35.2034 - Single filter ns/op: 47.5483 + Single filter ns/op: 47.4034 - Batched, prepared ns/op: 43.1559 + Batched, prepared ns/op: 42.2923 ... - Random filter ns/op: 150.697 + Random filter ns/op: 149.403 ---------------------------- Outside queries... - Dry run (980) ns/op: 34.6114 + Dry run (980) ns/op: 34.0405 - Single filter ns/op: 56.8326 + Single filter ns/op: 55.8414 - Batched, prepared ns/op: 48.2346 + Batched, prepared ns/op: 47.5667 - Random filter ns/op: 155.377 + Random filter ns/op: 153.942 Average FP rate %: 1.1386 Also, the FullFilterBitsReader ctor was responsible for a surprising amount of CPU in production, due in part to inefficient determination of the CACHE_LINE_SIZE used to construct the filter being read. The overwhelming common case (same as my CACHE_LINE_SIZE) is now substantially optimized, as shown with filter_bench with -new_reader_every=1 (old option - see below) (repeatable result): Inside queries... - Dry run (453) ns/op: 118.799 + Dry run (453) ns/op: 105.869 - Single filter ns/op: 82.5831 + Single filter ns/op: 74.2509 ... - Random filter ns/op: 224.936 + Random filter ns/op: 194.833 ---------------------------- Outside queries... - Dry run (aa1) ns/op: 118.503 + Dry run (aa1) ns/op: 104.925 - Single filter ns/op: 90.3023 + Single filter ns/op: 83.425 ... - Random filter ns/op: 220.455 + Random filter ns/op: 175.7 Average FP rate %: 1.13886 However PR#5936 has/will reclaim most of this cost. After that PR, the optimization of this code path is likely negligible, but nonetheless it's clear we aren't making performance any worse. Also fixed inadequate check of consistency between filter data size and num_lines. (Unit test updated.)

Summary: Plain table SSTs could crash sst_dump because of a bug in PlainTableReader that can leave table_properties_ as null. Even if it was intended not to keep the table properties in some cases, they were leaked on the offending code path. Steps to reproduce: $ db_bench --benchmarks=fillrandom --num=2000000 --use_plain_table --prefix-size=12 $ sst_dump --file=0000xx.sst --show_properties from [] to [] Process /dev/shm/dbbench/000014.sst Sst file format: plain table Raw user collected properties ------------------------------ Segmentation fault (core dumped) Also added missing unit testing of plain table full_scan_mode, and an assertion in NewIterator to check for regression.

Summary: In the current trace replay, all the queries are serialized and called by single threads. It may not simulate the original application query situations closely. The multi-threads replay is implemented in this PR. Users can set the number of threads to replay the trace. The queries generated according to the trace records are scheduled in the thread pool job queue. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5934 Test Plan: test with make check and real trace replay.

Summary: expose db stress test by providing db_stress_tool.h in public header. This PR does the following: - adds a new header, db_stress_tool.h, in include/rocksdb/ - renames db_stress.cc to db_stress_tool.cc - adds a db_stress.cc which simply invokes a test function. - update Makefile accordingly. Test Plan (dev server): ``` make db_stress ./db_stress ``` Pull Request resolved: https://github.com/facebook/rocksdb/pull/5937 Differential Revision: D17997647 Pulled By: riversand963 fbshipit-source-id: 1a8d9994f89ce198935566756947c518f0052410

Summary: The patch adds a new command line parameter --decode_blob_index to sst_dump. If this switch is specified, sst_dump prints blob indexes in a human readable format, printing the blob file number, offset, size, and expiration (if applicable) for blob references, and the blob value (and expiration) for inlined blobs. Pull Request resolved: https://github.com/facebook/rocksdb/pull/5926 Test Plan: Used db_bench's BlobDB mode to generate SST files containing blob references with and without expiration, as well as inlined blobs with and without expiration (note: the latter are stored as plain values), and confirmed sst_dump correctly prints all four types of records.

Summary: When there are concurrent flush job on the same CF, `OnFlushCompleted` can be called before the flush result being install to LSM. Fixing the issue by passing `FlushJobInfo` through `MemTable`, and the thread who commit the flush result can fetch the `FlushJobInfo` and fire `OnFlushCompleted` on behave of the thread actually writing the SST. Fix https://github.com/facebook/rocksdb/issues/5892 Pull Request resolved: https://github.com/facebook/rocksdb/pull/5908 Test Plan: Add new test. The test will fail without the fix.

Summary: Currently, db_bench only supports PutWithTTL operations for BlobDB but not regular Puts.
