The intent of this ticket is to put the hooks in place to support the behaviour programatically, adding support at the syntax level would be something to think about later IMO. > 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}}. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
