Summary: Seems like the cleanest way to resolve this is to move CompactedDBImpl into db/. CompactedDBImpl should probably live in the same place as DBImplReadonly since Opening the latter could end up instantiating the former. Both DBImplReadonly and CompactedDBImpl inherit from DBImpl access protected members of DBImpl( and the latter access friendly private methods).

Summary: We occasionally get write stalls (>1s Write() calls) on HDD under read load. The following timers explain almost all of the stalls: - perf_context.db_mutex_lock_nanos - perf_context.db_condition_wait_nanos - iostats_context.open_time - iostats_context.allocate_time - iostats_context.write_time - iostats_context.range_sync_time - iostats_context.logger_time In my experiments each of these occasionally takes >1s on write path under some workload. There are rare cases when Write() takes long but none of these takes long. Test Plan: Added code to our application to write the listed timings to log for slow writes. They usually add up to almost exactly the time Write() call took.

Summary: Optimistic transactions supporting begin/commit/rollback semantics. Currently relies on checking the memtable to determine if there are any collisions at commit time. Not yet implemented would be a way of enuring the memtable has some minimum amount of history so that we won't fail to commit when the memtable is empty. You should probably start with transaction.h to get an overview of what is currently supported. Test Plan: Added a new test, but still need to look into stress testing.

Summary: Added a couple functions to WriteBatchWithIndex to make it easier to query the value of a key including reading pending writes from a batch. (This is needed for transactions). I created write_batch_with_index_internal.h to use to store an internal-only helper function since there wasn't a good place in the existing class hierarchy to store this function (and it didn't seem right to stick this function inside WriteBatchInternal::Rep). Since I needed to access the WriteBatchEntryComparator, I moved some helper classes from write_batch_with_index.cc into write_batch_with_index_internal.h/.cc. WriteBatchIndexEntry, ReadableWriteBatch, and WriteBatchEntryComparator are all unchanged (just moved to a different file(s)). Test Plan: Added new unit tests.

Summary: Some Mongo+Rocks datasets in Parse's environment are not doing compactions very frequently. During the quiet period (with no IO), we'd like to schedule compactions so that our reads become faster. Also, aggressively compacting during quiet periods helps when write bursts happen. In addition, we also want to compact files that are containing deleted key ranges (like old oplog keys). All of this is currently not possible with CompactRange() because it's single-threaded and blocks all other compactions from happening. Running CompactRange() risks an issue of blocking writes because we generate too much Level 0 files before the compaction is over. Stopping writes is very dangerous because they hold transaction locks. We tried running manual compaction once on Mongo+Rocks and everything fell apart. MarkForCompaction() solves all of those problems. This is very light-weight manual compaction. It is lower priority than automatic compactions, which means it shouldn't interfere with background process keeping the LSM tree clean. However, if no automatic compactions need to be run (or we have extra background threads available), we will start compacting files that are marked for compaction.

Summary: Just couple of small changes: 1. removed signal_test, since it doesn't seem useful and we don't even run it as part of `make check` 2. moved perf_context_test to TESTS instead of PROGRAMS 3. `make release` probably shouldn't compile benchmarks. We currently rely on `make release` building db_bench (via Jenkins), so I left db_bench there. This is just a minor cleanup. We need to rethink our targets since they are a bit messy right now. We can do this during our tech debt week.

Summary: WriteBatch and WriteBatchWithIndex now both inherit from a common abstract base class. This makes it easier to write code that is agnostic toward the implementation of the particular write batch. In particular, I plan on utilizing this abstraction to allow transactions to support using either implementation of a write batch. Test Plan: modified existing WriteBatchWithIndex tests to test new functions. Running all tests.

Summary: Here's my proposal for making our LOGs easier to read by machines. The idea is to dump all events as JSON objects. JSON is easy to read by humans, but more importantly, it's easy to read by machines. That way, we can parse this, load into SQLite/mongo and then query or visualize. I started with table_create and table_delete events, but if everybody agrees, I'll continue by adding more events (flush/compaction/etc etc) Test Plan: Ran db_bench.

Summary: Any time one would modify a dependent of any *test*.cc file, "make" would fail to rebuild the affected test binaries, e.g., db_test. That was due to the fact that we deliberately excluded those test-related files from the definition of SOURCES and only $(SOURCES) was used to create the automatically-generated .d dependency files. The fix is to generate a .d file for every source file. * src.mk: New file. Defines LIB_SOURCES, MOCK_SOURCES and TEST_BENCH_SOURCES. * Makefile: Include src.mk. Reflect s/SOURCES/LIB_SOURCES/ renaming. * build_tools/build_detect_platform: Remove the code that was used to generate SOURCES= and MOCK_SOURCES= definitions in make_config.mk. Those lists of files are now hard-coded in src.mk. Hard-coding this list of sources is desirable, because without that, one risks including stray .cc files in a build. Not reproducible. Test Plan: Touch a file used by db_test's dependent .o files and ensure that they are all recompiled. Before, none would be: $ touch db/db_impl.h && make db_test CC db/db_test.o CC db/column_family.o CC db/db_filesnapshot.o CC db/db_impl.o CC db/db_impl_debug.o CC db/db_impl_readonly.o CC db/forward_iterator.o CC db/internal_stats.o CC db/managed_iterator.o CC db/repair.o CC db/write_batch.o CC utilities/compacted_db/compacted_db_impl.o CC utilities/ttl/db_ttl_impl.o CC util/ldb_cmd.o CC util/ldb_tool.o CC util/sst_dump_tool.o CC util/xfunc.o CCLD db_test Reviewers: ljin, igor.sugak, igor, rven, sdong Reviewed By: sdong Subscribers: yhchiang, adamretter, fyrz, dhruba Differential Revision: https://reviews.facebook.net/D33849
