A:DBwithTTLitself does not provide an upper time bound. Expired keys will be removed when they are part of any compaction. However, there is no guarantee that when such compaction will start. For instance, if you have a certain key-range that is never updated, then compaction is less lik...

Keys and values are treated as pure byte streams. There is no limit to the size of a key or a value. The Get API allows an application to fetch a single key-value from the database. The MultiGet API allows an application to retrieve a bunch of keys from the database. All the keys...
Unlike libaio, no registration and callback is required, and memory doesn't need to be aligned either. Therefore, we did not encounter any trouble when using this interface to transform the original psync IO of RocksDB, but simply replaced their function names. 3. Synchronization, locks, and...
If value is set 0 then no automatic prefetching will be done by rocksdb. Also changing the value will only affect files opened after the change. Add suppport to extend DB::VerifyFileChecksums API to also verify blob files checksum. When using the new BlobDB, the amount of data written ...
Fix useless no-op compactions scheduled upon snapshot release when options.disable-auto-compactions = true. Fix a bug when max_write_buffer_size_to_maintain is set, immutable flushed memtable destruction is delayed until the next super version is installed. A memtable is not added to delete...
