@Rob - he's probably referring to the thread titled "Reasons for nodes not compacting?" where Tyler speculates that the tables are falling below the cold read threshold for compaction. He speculated it may be a bug. At the same time in a different thread, Roland had a similar problem, and Tyler's

Thanks Roland. Good to know, I will try that. Do you know the JIRA ticket number of that bug? Thanks, Flavien On 19 January 2015 at 06:15, Roland Etzenhammer wrote: > Hi Flavien, > > I hit some problem with minor compations recently (just some days ago) - > but with many more tables. In my case

Hi Flavien, I hit some problem with minor compations recently (just some days ago) - but with many more tables. In my case compactions got not triggered, you can check this with nodetool compactionstats. Reason for me was that those minor compactions did not get triggered since there were al

Seems like Size Tier Compaction is based on table, which table did you set the compaction strategy? A minor compaction does not involve all the tables in a keyspace.

Compaction failing to trigger

Hi, I am using Size Tier Compaction (Cassandra 2.1.2). Minor compaction is not triggering even though it should. See the SSTables on disk: http://pastebin.com/PSwZ5mrT You can see that we have 41 SSTable between 60MB and 85MB, which should trigger compaction unless I am missing something. Is tha
