-------------------------------------------
Summary: Extend support for post-reconcilliation processing to all
read commands
Key: CASSANDRA-11175
URL: https://issues.apache.org/jira/browse/CASSANDRA-11175
Project: Cassandra
Issue Type: Improvement
Components: CQL
Reporter: Sam Tunnicliffe
Assignee: Sam Tunnicliffe
Priority: Minor
Fix For: 3.x
CASSANDRA-8717 introduced limited support for processing or transformation of
query results on the coordinator, which occurs after the results from
individual replicas have been reconciled. At the moment this is limited to
queries which utilise secondary indexes and the post-processing function itself
is provided by the index implementation. It would be useful if this were
expanded so that any read command may include a post-reconcilliation processing
step. A straightforward way to control this would be via a custom
{{QueryHandler}}.
