-------------------------------------
Summary: Materialized view support for Cassandra adapter
Key: CALCITE-1104
URL: https://issues.apache.org/jira/browse/CALCITE-1104
Project: Calcite
Issue Type: Improvement
Reporter: Michael Mior
Assignee: Julian Hyde
Priority: Minor
I managed to get support for a subset of Cassandra [materialized
views|https://www.datastax.com/dev/blog/new-in-cassandra-3-0-materialized-views].
( Thanks owed to some hints from [~maryannxue]!)
The one thing I noticed so far which is not supported is UUID literals in the
WHERE clauses in the Cassandra view definition. However, I don't think that's a
common use case. The adapter will log a warning if it encounters a view that
can't be processed. At the very least, the view will be exposed as a table to
Calcite (it wasn't in the previous version of the adapter).
As per [CALCITE-1101|https://issues.apache.org/jira/browse/CALCITE-1101], there
is probably a better way to hook in and add these views. I thought I would
still put this up for now. I'd still like to add some tests before considering
this viable.
