Google LevelDB inspired compaction in Cassandra 1.0
- rbranson 15y agoLeveledCompactionStrategy is still a new piece of kit for Cassandra, and probably should be used sparingly. If I've understood anything I've been told, it's best fit is if the workload involves many random overwrites distributed over a large set of rows & columns. It's also currently not concurrent, so if nodes have high I/O throughput and many cores, it's even less likely to perform as well as standard compaction.
- jbellis 15y agoSort of. (a) the times you want to dedicate more than one core to compaction are rare, and (b) you can still use multiple cores within a compaction set. I'll update the post with more details.
