[jira] [Updated] (CASSANDRA-15364) Avoid over scanning data
directories in LogFile.verify()
[ https://issues.apache.org/jira/browse/CASSANDRA-15364?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Marcus Eriksson updated CASSANDRA-15364:
----------------------------------------
Description: We currently list the data directory for every {REMOVE} record in the file in {LogFile.verify()} - this can get very expensive during startup when we call {LogTransaction.removeUnfinishedLeftovers()}. In {LogRecord.getExistingFiles(Set<String> absoluteFilePaths)} we also fully parse the file name of the sstables found, here we only need to prefix match. (was: We currently list the data directory for every `REMOVE` record in the file in `LogFile.verify()` - this can get very expensive during startup when we call `LogTransaction.removeUnfinishedLeftovers()`. In `LogRecord.getExistingFiles(Set<String> absoluteFilePaths)` we also fully parse the file name of the sstables found, here we only need to prefix match.)
