[jira] [Created] (CALCITE-5364) In materialized view substitution, use custom time frames
Julian Hyde created CALCITE-5364:
Summary: In materialized view substitution, use custom time frames
Key: CALCITE-5364
URL: https://issues.apache.org/jira/browse/CALCITE-5364
Project: Calcite
Issue Type: Bug
Reporter: Julian Hyde
Custom time frames were added in CALCITE-5155, and part of the definition of a
custom time frame is the time frames it rolls up to. Materialized view
substitution should use this information, so that you can create materialized
views on custom time frames such as '15 minutes' or '21 days' and have them
roll up.
Also you should be able to use materialized views (on custom and regular time
frames) to answer queries with custom time frames (e.g. {{FLOOR(orderDate TO
month6)}}).

[jira] [Created] (CALCITE-5363) Move DATEADD, DATEDIFF, DATE_PART from Babel to Core parser
Julian Hyde created CALCITE-5363: Summary: Move DATEADD, DATEDIFF, DATE_PART from Babel to Core parser Key: CALCITE-5363 URL: https://issues.apache.org/jira/browse/CALCITE-5363 Project: Calcite Issue Type: Bug Reporter: Julian Hyde Move the DATEADD, DATEDIFF, DATE_PART functions (maybe also DATEPART) from Babel to Core parser. They require special parsing (maybe not quite as special, following CALCITE-5155) but it would be nice if they could be enabled just by setting 'lib=postgres' without switching parser. -- This message was sent by Atlassian Jira (v8.20.10#820010)

Returning the Intermediate Representation of the rewrite rules
Dear Apache Calcite development team, I am currently working on a research project in which I am considering Apache Calcite for the parsing stage. I was wondering if there exists an API to return the intermediate representation (relational tree) for the pre-defined SQL rewrite rules? For instance, a relational tree for push-filter-though-join rule in format (LHS relational tree => RHS relational tree). The motivation behind this is to have a set of rewrite rules in the same format (IR) as the output of opTree.explain() to build new optimizers. Thanks for your time. Many thanks, George Barbulescu
