Isn't that a problem common to all SSTable-based databases?
Is LevelDB any worse than HBase or Cassandra in this area?
- snaky 13y agoYes, it seems like Cassandra is suffering from compacting too, although maybe not so ugly as LevelDB. The only solution I've found is Castle backend from Acunu [1], but there were no updates from 2011 [2] and it looks really heavy (with kernel module and all that) [1] http://www.slideshare.net/acunu/cassandra-on-castle http://www.slideshare.net/acunu/cassandra-on-castle [2] https://bitbucket.org/acunu/fs.hg https://bitbucket.org/acunu/fs.hg
