* Enabled checkpoint on readonly db (DBImplReadOnly).
|
||||
* Make DB ignore dropped column families while committing results of atomic flush.
|
||||
* RocksDB may choose to preopen some files even if options.max_open_files != -1. This may make DB open slightly longer.
|
||||
* For users of dictionary compression with ZSTD v0.7.0+, we now reuse the same digested dictionary when compressing each of an SST file's data blocks for faster compression speeds.

### Public API Change
|
||||
* Transaction::GetForUpdate is extended with a do_validate parameter with default value of true. If false it skips validating the snapshot before doing the read. Similarly ::Merge, ::Put, ::Delete, and ::SingleDelete are extended with assume_tracked with default value of false. If true it indicates that call is assumed to be after a ::GetForUpdate.
