We are seeing read QPS as high as 5M (we will write a separate blog post on this). + +<!--truncate--> + +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. |
