Subject [jira] [Commented] (CASSANDRA-14619) Create fqltool compare command
Date Fri, 31 Aug 2018 16:31:00 GMT

    [ https://issues.apache.org/jira/browse/CASSANDRA-14619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16598970#comment-16598970
] 

Jason Brown commented on CASSANDRA-14619:
-----------------------------------------

[~krummas] added an extra commit (e608fb24d3b00cb623fa9ca7b826b7a3bf2b9064) for versioning
the replay output and querylog files. 

In that commit, every columnDefinition and row entry that is written out is prefixed with
a 4-byte version number. Instead of writing out the (presumably) same version number many
times in the file, can you write it once at the beginning of the file? I think you'd save
a lot on file size that way.

> We need a {{fqltool compare}} command that can take the recorded runs from CASSANDRA-14618
and compares them, it should output any differences and potentially all queries against the
mismatching partition up until the mismatch
