-----------------------------------------
Idea: user can push reconciliation logic through the UDF API ?
> Extend support for post-reconcilliation processing to all read commands

> 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}}.
