Re: compaction with LCS
Anyone has seen similar behavior with LCS, please do let me know, It will be good to know this can happen.

Re: compaction with LCS
Looks like some of the nodes have higher sstables on L0 and compaction is running there, so only few nodes run compaction at a time and the preference is given to lower level nodes for compaction before going to higher levels ? so is compaction cluster aware then ?

compaction with LCS
hello, on doing cfstats for the column family i see SSTables in each level: [1, 10, 109/100, 1, 0, 0, 0, 0, 0] i thought compaction would trigger since the 3rd level tables are move than expected number, but on doing compactionstats its shows "n/a" -- any reason why its not triggering, should i be worried ? we have 5 node cluster running 2.0.15 cassandra version, thanks anishek
