------------------------------------------
Summary: Don't check for overlap with sstables that have had their
start positions moved in LCS
Key: CASSANDRA-8739
URL: https://issues.apache.org/jira/browse/CASSANDRA-8739
Project: Cassandra
Issue Type: Bug
Reporter: Marcus Eriksson
Assignee: Marcus Eriksson
When picking compaction candidates in LCS, we check that we won't cause any
overlap in the higher level. Problem is that we compare the files that have had
their start positions moved meaning we can cause overlap. We need to also
include the tmplink files when checking this.
Note that in 2.1 overlap is not as big problem as earlier, if adding an sstable
would cause overlap, we send it back to L0 instead, meaning we do a bit more
compaction but we never actually have overlap.
