--------------------------------------
Summary: Cassandra stops compacting
Key: CASSANDRA-10270
URL: https://issues.apache.org/jira/browse/CASSANDRA-10270
Project: Cassandra
Issue Type: Bug
Components: Core
Environment: linux (google cloud click-to-deploy, default settings, 3
nodes)
Reporter: Adam Bliss
Fix For: 2.2.1
My cassandra cluster won't keep compacting. I notice that if I restart, it does
compact for a while, but after a time it stops. As a result, after adding a
bunch of rows, I ended up with about 1000 sstables per node.
I'll attach more logs in a minute, but it seems like this might be the most
relevant part:
