Summary: Nodetool Compact set the compaction type incorrectly
Key: CASSANDRA-18055
URL: https://issues.apache.org/jira/browse/CASSANDRA-18055
Project: Cassandra
Issue Type: Bug
Components: Local/Compaction, Tool/nodetool
Reporter: maxwellguo
Attachments: 20221116235846.jpg
When using nodetool compactionstats to see what does the c*'s compactions are
doing ,the output has got a column named "compaction type", but It seem that
major compaction and minor compaction 's type are all name Compaction, after
read the code I found that may be the the MAJOR_COMPACTION OperationType is not
setted into AbstractCompactionTask
at this method : CompactionStrategyManager -> getMaximalTasks .When we peform a
major compact without any arguments we will got this execute path :
{code:java}
// Some comments here
Compact.java : probe.forceKeyspaceCompaction(splitOutput, keyspace, tableNames);
--->
ColumnFamilyStore.java : cfStore.forceMajorCompaction(splitOutput);
--->
CompactionManager.java : submitMaximal(cfStore, gcBefore, splitOutput,
OperationType.MAJOR_COMPACTION);
{code}
Unfortunately OperationType.MAJOR_COMPACTION is not rightly setted.
see the picture on the right I perform a major compact , and on the left the
compactionstats show the type is only Compaction ;
I think it is import for us to know wether the task is a major or a minor .
