Subject [jira] [Commented] (CASSANDRA-11344) Fix bloom filter sizing with LCS
Date Tue, 15 Mar 2016 15:36:33 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-11344?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15195492#comment-15195492

Paulo Motta commented on CASSANDRA-11344:
-----------------------------------------

bq. before it only summed up the total size of the sstables, now it gets an approximated expected
compaction ratio.

nice catch. dtest look good now. I resubmitted CASSANDRA-9830 cstar runs to make sure results
are still consistent with the new estimation. will mark this as ready to commit when that
is finished and looks good.

as a minor style nit before committing, could you just move the compaction ratio estimation
to a separate method so it doesn't crowd the {{MaxSSTableSizeWriter}} constructor?
