Summary: Instead of using samples directly, we now support passing the samples through zstd's dictionary generator when `CompressionOptions::zstd_max_train_bytes` is set to nonzero. If set to zero, we will use the samples directly as the dictionary -- same as before. Note this is the first step of #2987, extracted into a separate PR per reviewer request.

Summary: Previously setting `write_buffer_size` with `SetOptions` would only apply to new memtables. An internal user wanted it to take effect immediately, instead of at an arbitrary future point, to prevent OOM. This PR makes the memtable's size mutable, and makes `SetOptions()` mutate it. There is one case when we preserve the old behavior, which is when memtable prefix bloom filter is enabled and the user is increasing the memtable's capacity. That's because the prefix bloom filter's size is fixed and wouldn't work as well on a larger memtable.

Summary: CreateColumnFamily() releases DB mutex after adding column family to the set and install super version (to write option file), so if users call GetAggregatedIntProperty() in the middle, then super version will be null and the process will crash. Fix it by skipping those column families without super version installed. Maybe we should also fix the problem of releasing the lock when reading option file, but it is more risky. so I'm doing a quick and safer fix and we can investigate it later.

Summary: Some users want to monitor column family activity in their custom memtable implementations. Previously there was no way to figure out with which column family a memtable is associated. This diff: - adds an overload to MemTableRepFactory::CreateMemTableRep() that provides the CF ID. For compatibility, its default implementation calls the old overload. - updates MemTable to create MemTableRep's using the new overload.

Summary: First cut for early review; there are few conceptual points to answer and some code structure issues. For conceptual points - - restriction-wise, we're going to disallow ingest_behind if (use_seqno_zero_out=true || disable_auto_compaction=false), the user is responsible to properly open and close DB with required params - we wanted to ingest into reserved bottom most level. Should we fail fast if bottom level isn't empty, or should we attempt to ingest if file fits there key-ranges-wise? - Modifying AssignLevelForIngestedFile seems the place we we'd handle that. On code structure - going to refactor GenerateAndAddExternalFile call in the test class to allow passing instance of IngestionOptions, that's just going to incur lots of changes at callsites.

Summary: Current write stalling system has the problem of lacking of positive feedback if the restricted rate is already too low. Users sometimes stack in very low slowdown value. With the diff, we add a positive feedback (increasing the slowdown value) if we recover from slowdown state back to normal. To avoid the positive feedback to keep the slowdown value to be to high, we add issue a negative feedback every time we are close to the stop condition. Experiments show it is easier to reach a relative balance than before. Also increase level0_stop_writes_trigger default from 24 to 32. Since level0_slowdown_writes_trigger default is 20, stop trigger 24 only gives four files as the buffer time to slowdown writes. In order to avoid stop in four files while 20 files have been accumulated, the slowdown value must be very low, which is amost the same as stop. It also doesn't give enough time for the slowdown value to converge. Increase it to 32 will smooth out the system.

Summary: This PR is based on nbronson's diff with small modifications to wire it up with existing interface. Comparing to previous version, this approach works better for inserting keys in decreasing order or updating the same key, and impose less restriction to the prefix extractor. ---- Summary from original diff ---- This diff introduces a single InlineSkipList::Insert that unifies the existing sequential insert optimization (prev_), concurrent insertion, and insertion using externally-managed insertion point hints. There's a deep symmetry between insertion hints (cursors) and the concurrent algorithm. In both cases we have partial information from the recent past that is likely but not certain to be accurate. This diff introduces the struct InlineSkipList::Splice, which encodes predecessor and successor information in the same form that was previously only used within a single call to InsertConcurrently. Splice holds information about an insertion point that can be used to levera Closes https://github.com/facebook/rocksdb/pull/1561 Differential Revision: D4217283 Pulled By: yiwu-arbug fbshipit-source-id: 33ee437

Summary: Currently our skip-list have an optimization to speedup sequential inserts from a single stream, by remembering the last insert position. We extend the idea to support sequential inserts from multiple streams, and even tolerate small reordering wihtin each stream. This PR is the interface part adding the following: - Add `memtable_insert_prefix_extractor` to allow specifying prefix for each key. - Add `InsertWithHint()` interface to memtable, to allow underlying implementation to return a hint of insert position, which can be later pass back to optimize inserts. - Memtable will maintain a map from prefix to hints and pass the hint via `InsertWithHint()` if `memtable_insert_prefix_extractor` is non-null.
