Benjamin Lerer updated CASSANDRA-16944: --------------------------------------- Bug Category: Parent values: Code(13163) Complexity: Normal Discovered By: Code Inspection Fix Version/s: 4.0.x 3.11.x 3.0.x Severity: Low Status: Open (was: Triage Needed) > Single partition reads can read more SSTables than required > ------------------------------------------------------------ > > Key: CASSANDRA-16944 > URL: https://issues.apache.org/jira/browse/CASSANDRA-16944 > Project: Cassandra > Issue Type: Bug > Components: Legacy/Local Write-Read Paths > Reporter: Benjamin Lerer > Assignee: Benjamin Lerer > Priority: Normal > Fix For: 3.0.x, 3.11.x, 4.0.x > > > For some scenarios involving row deletions, range deletions or static > columns, the logic of > {{SinglePartitionReadCommand.queryMemtableAndSSTablesInTimestampOrder}} might > trigger more SSTables reads that expected. > For row deletions and range deletions the reasons is that the logic do not > take them into account. Once we hit a deleted row (caused by a row deletion > or a range deletion) with a timestamp higher than the one of the next SStable > we know that we can stop reading more SSTables. > For static columns the problems seems to have been introduced by the changes > in CASSANDRA-16671. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: commits-unsubscr...@cassandra.apache.org For additional commands, e-mail: commits-h...@cassandra.apache.org
