-------------------------------------------
Summary: Cassandra TWCS is not removing fully expired tables
Key: CASSANDRA-13005
URL: https://issues.apache.org/jira/browse/CASSANDRA-13005
Project: Cassandra
Issue Type: Bug
Components: Compaction
Environment: Linux
Cassandra 3.0.5 / Casandra 3.9
Reporter: Christian Esken
Attachments: sstablemetadata-empty-type-that-is-3GB.txt
We have a table where all columns are stored with TTL of maximum 4 hours.
Usually TWCS compaction properly removes expired data via tombstone compaction
and also removes fully expired tables. The number of SSTables is nearly
constant since weeks. Good.
The problem: Suddenly TWCS does not remove old SSTables any longer. They are
being recreated frequently (judging form the filer creation timestamp), but the
number of tables is growing.
- sstablemetadata shows strange data, as if the table is completely empty.
- sstabledump throws an Exception when running it on such a SSTable
