----------------------------------------
Summary: CBO costing of all physical operators in a query plan
Key: ASTERIXDB-3246
URL: https://issues.apache.org/jira/browse/ASTERIXDB-3246
Project: Apache AsterixDB
Issue Type: Bug
Components: COMP - Compiler
Affects Versions: 0.9.6
Reporter: Vijay Sarathy
In the first version of CBO, the following operators were costed:
SELECT
UNNEST_MAP
DATA_SCAN
EXCHANGE
INNER_JOIN
The costing of these subset of operators provides sufficient information to
generate good plans for a vast majority of queries.
The costing of the other operators (like group by, order by, limit, etc.) needs
to be completed for full coverage of all the operators.
