-----------------------------------------
Summary: Add client warnings and abort to tombstone and
coordinator reads which go past a low/high watermark
Key: CASSANDRA-16850
URL: https://issues.apache.org/jira/browse/CASSANDRA-16850
Project: Cassandra
Issue Type: Improvement
Components: Observability/Logging
Reporter: David Capwell
Assignee: David Capwell
We currently will abort queries if we hit too many tombstones, but its common
that we would want to also warn clients (client warnings) about this before we
get that point; its also common that different logic would like to be able to
warn/abort about client options (such as reading a large partition). To allow
this we should add a concept of low/high watermarks (warn/abort) to tombstones
and coordinator reads.
