C. Scott Andreas updated CASSANDRA-8721:
----------------------------------------
Component/s: Observability
> expose "shadowed" columns in tracing output
> -------------------------------------------
>
> Key: CASSANDRA-8721
> URL: https://issues.apache.org/jira/browse/CASSANDRA-8721
> Project: Cassandra
> Issue Type: Improvement
> Components: Observability
> Reporter: Robert Coli
> Priority: Trivial
>
> Current tracing messages expose how many tombstones are read in order to read
> live columns, but they do not expose shadowed columns. Shadowed columns are
> columns where the timestamp for a given column is lower than the highest
> timestamp for that column.
> It would be useful for users who are tracing queries to understand how many
> shadowed columns are being read-than-ignored.
