The cassandra adapter registers materialized views[1] which can be used to
register an index.
The MaterializedViewFilterScanRule might be helpful in getting the index to
be chosen.

Dennis,
Looking at the code I think the SQL2REL_CONVERTER_CONFIG_BUILDER hook might
be the best way to add hints for use via sql.
Even though the documentation says hooks should be used for
debugging/testing I think practically they are needed to accomplish tasks
from adapters for eg the
The HintStrategyTable can be defined in your adapter code for eg see

Hi,
I would like to request a review for CALCITE-5240, it
modifies MaterializedViewRule so that views that do a rollup (for eg a
group by on a datetime column floored to day) can be used when a query
contains a range predicate on the same column.
At my company we used calcite to develop a query

Hi,
I get an error while using TIMESTAMPDIFF with RelBuilder. For this example
code
@Test void testRun2() throws Exception {
// Equivalent SQL:
// SELECT TIMESTAMP(SECOND, HIREDATE, TIMESTAMP'1970-01-01') FROM EMP
final RelBuilder builder = RelBuilder.create(config().build());

Hi,
The existing MaterializedViewRule is not applied when the materialized view
does not have a view predicate but the query contains a predicate. For eg
for the following materialized view
SELECT eventid, floor(ts to minute), count(*) as cnt
FROM events
GROUP BY eventid, floor(ts TO

We are using calcite to query data in Kudu. We have implemented our own
sort rule that merges rows returned from kudu when a queries orders by
columns in the same order as the primary key of the kudu table.
For a query that does a left join, in order to get the planner to use my
sort rule I had to
I am looking into the possibility of using row value constructors for
paging through data. The query would be of the form
SELECT * FROM t WHERE (pk1, pk2) > (2,'bar');
which should logically be equivalent to
SELECT * FROM t WHERE pk1 > 2 OR (pk1=2 AND pk2>'bar')
