Robert Stupp updated CASSANDRA-14892: ------------------------------------- Status: Ready to Commit (was: Patch Available) > Possible corruption in compressed files with uncompressed chunks > ---------------------------------------------------------------- > > Key: CASSANDRA-14892 > URL: https://issues.apache.org/jira/browse/CASSANDRA-14892 > Project: Cassandra > Issue Type: Bug > Components: Local Write-Read Paths > Reporter: Branimir Lambov > Assignee: Branimir Lambov > Priority: Major > > When deciding to switch to writing a chunk uncompressed in a compressed file > (see CASSANDRA-10520) and that chunk is smaller than the full chunk size > (only currently happens in the last chunk of the file), it may very rarely > happen that the chunk is: > - bigger than the compression limit when compressed > - smaller than the compression limit when left uncompressed > If this happens the writer will write it uncompressed, but the reader will > treat it as compressed and fail when attempting to read it. > Such chunks should be padded with 0s to the minimum uncompressed size. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
