Check out the new RocksDB 2.8 release on [Github](https://github.com/facebook/rocksdb/releases/tag/2.8.fb).
|
|
|
|
RocksDB 2.8. is mostly focused on improving performance for in-memory workloads. We are seeing read QPS as high as 5M (we will write a separate blog post on this).

Here is the summary of new features:
|
|
|
|
* Added a new table format called PlainTable, which is optimized for RAM storage (ramfs or tmpfs). You can read more details about it on [our wiki](https://github.com/facebook/rocksdb/wiki/PlainTable-Format).
|
|
|
|
|
|
* New prefixed memtable format HashLinkedList, which is optimized for cases where there are only a few keys for each prefix.
|
|
|
|
|
|
* Merge operator supports a new function PartialMergeMulti() that allows users to do partial merges against multiple operands. This function enables big speedups for workloads that use merge operators.
|
|
|
|
|
|
* Added a V2 compaction filter interface. It buffers the kv-pairs sharing the same key prefix, process them in batches, and return the batched results back to DB.
|
|
|
|
|
|
* Geo-spatial support for locations and radial-search.
|
|
|
|
|
|
* Improved read performance using thread local cache for frequently accessed data.
|
|
|
|
|
|
* Stability improvements -- we're now ignoring partially written tailing record to MANIFEST or WAL files.
|

|
|

We have also introduced small incompatible API changes (mostly for advanced users). You can see full release notes in our [HISTORY.my](https://github.com/facebook/rocksdb/blob/2.8.fb/HISTORY.md) file.
