Summary: In prepration for running multiple threads at the same time during a compaction job, this patch assigns each subcompaction its own state (instead of sharing the one global CompactionState). Each subcompaction then uses this state to update its statistics, keep track of its snapshots, etc. during the course of execution. Then at the end of all the executions the statistics are aggregated across the subcompactions so that the final result is the same as if only one larger compaction had run.

Summary: When we first started, max_background_flushes was 0 by default and compaction thread was executing flushes (since there was no flush thread). Then, we switched the default max_background_flushes to 1. However, we still support the case where there is no flush thread and flushes are done in compaction. This is making our code a bit more complicated. By not supporting this use-case we can make our code simpler. We have a special case that when you set max_background_flushes to 0, we schedule the flush to execute on the compaction thread. Test Plan: make check (there might be some unit tests that depend on this behavior) Reviewers: IslamAbdelRahman, yhchiang, sdong Reviewed By: sdong Subscribers: dhruba, leveldb Differential Revision: https://reviews.facebook.net/D41931

Summary: For transactions, we are using the memtables to validate that there are no write conflicts. But after flushing, we don't have any memtables, and transactions could fail to commit. So we want to someone keep around some extra history to use for conflict checking. In addition, we want to provide a way to increase the size of this history if too many transactions fail to commit. After chatting with people, it seems like everyone prefers just using Memtables to store this history (instead of a separate history structure). It seems like the best place for this is abstracted inside the memtable_list. I decide to create a separate list in MemtableListVersion as using the same list complicated the flush/installalflushresults logic too much. This diff adds a new parameter to control how much memtable history to keep around after flushing. However, it sounds like people aren't too fond of adding new parameters. So I am making the default size of flushed+not-flushed memtables be set to max_write_buffers. This should not change the maximum amount of memory used, but make it more likely we're using closer the the limit. (We are now postponing deleting flushed memtables until the max_write_buffer limit is reached). So while we might use more memory on average, we are still obeying the limit set (and you could argue it's better to go ahead and use up memory now instead of waiting for a write stall to happen to test this limit). However, if people are opposed to this default behavior, we can easily set it to 0 and require this parameter be set in order to use transactions. Test Plan: Added a xfunc test to play around with setting different values of this parameter in all tests. Added testing in memtablelist_test and planning on adding more testing here.

Removed assignment. scan-build report: http://home.fburl.com/~sugak/latest20/report-9b77d2.html#EndPath **db/db_iter.cc** `skipping` local variable is assigned to false. Then in the next switch block the only "non return" case assign `skipping` to true, the rest cases don't use it and all do return. scan-build report: http://home.fburl.com/~sugak/latest20/report-13fca7.html#EndPath **db/log_reader.cc** In `bool Reader::SkipToInitialBlock()` `offset_in_block` local variable is assigned to 0 `if (offset_in_block > kBlockSize - 6)` and then never used. Removed the assignment and renamed it to `initial_offset_in_block` to avoid confusion. scan-build report: http://home.fburl.com/~sugak/latest20/report-a618dd.html#EndPath In `bool Reader::ReadRecord(Slice* record, std::string* scratch)` local variable `in_fragmented_record` in switch case `kFullType` block is assigned to false and then does `return` without use. In the other switch case `kFirstType` block the same `in_fragmented_record` is assigned to false, but later assigned to true without prior use. Removed assignment for both cases. scan-build reprots: http://home.fburl.com/~sugak/latest20/report-bb86b0.html#EndPath http://home.fburl.com/~sugak/latest20/report-a975be.html#EndPath **table/plain_table_key_coding.cc** Local variable `user_key_size` is assigned when declared. But then in both places where it is used assigned to `static_cast<uint32_t>(key.size() - 8)`. Changed to initialize the variable to the proper value in declaration. scan-build report: http://home.fburl.com/~sugak/latest20/report-9e6b86.html#EndPath **tools/db_stress.cc** Missing `break` in switch case block. This seems to be a bug. Added missing `break`.

Summary: 1. Make filter_block.h a base class. Derive block_based_filter_block and full_filter_block. The previous one is the traditional filter block. The full_filter_block is newly added. It would generate a filter block that contain all the keys in SST file. 2. When querying a key, table would first check if full_filter is available. If not, it would go to the exact data block and check using block_based filter. 3. User could choose to use full_filter or tradional(block_based_filter). They would be stored in SST file with different meta index name. "filter.filter_policy" or "full_filter.filter_policy". Then, Table reader is able to know the fllter block type. 4. Some optimizations have been done for full_filter_block, thus it requires a different interface compared to the original one in filter_policy.h. 5.

Also, internally, we include: #include "utilities/backupable/backupable_db.h" // internal header #include "utilities/backupable_db.h" // public header which is confusing. This way, when we install rocksdb as a system library, we can just copy `include/rocksdb` directory to system's header files. We can't really copy `utilities` directory to system's header files.
