After performing "nodetool compact" command the disk usage was doubled. nodetool info reports that the load is 74G (same as before compaction) while the size of the data folder on disk is 133GB (was about 74G before compaction).

Extremly slow inserts on LAN

2010-05-09 Thread Arie Keren
While making our first steps with Cassandra, we experience slow inserts working on LAN. Inserting 7000 keys with 1 column family takes about 10 seconds when Cassandra server running on the same host with the client. But when server runs on a different host on LAN, the same inserts take more th
