mck updated CASSANDRA-11166:
----------------------------
Component/s: Observability
> Range tombstones not accounted in tracing/cfstats
> -------------------------------------------------
>
> Key: CASSANDRA-11166
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11166
> Project: Cassandra
> Issue Type: Bug
> Components: Observability
> Reporter: Anubhav Kale
> Priority: Minor
> Fix For: 3.11.2, 4.0
>
>
> I noticed an inconsistent behavior on deletes. Not sure if it is intentional.
> The summary is:
> If a table is created with TTL or if rows are inserted in a table using TTL,
> when its time to expire the row, tombstone is generated (as expected) and
> cfstats, cqlsh tracing and sstable2json show it.
> However, if one executes a delete from table query followed by a select *,
> neither cql tracing nor cfstats shows a tombstone being present. However,
> sstable2json shows a tombstone.
> Is this situation treated differently on purpose ? In such a situation, does
> Cassandra not have to scan tombstones (seems odd) ?
> Also as a data point, if one executes a delete <some-column> from table,
> cqlsh tracing, nodetool cfstats, and sstable2json all show a consistent
> result (tombstone being present).
> As a end user, I'd assume that deleting a row either via TTL or explicitly
> should show me a tombstone. Is this expectation reasonable ? If not, can this
> behavior be clearly documented ?
