-------------------------------------------
Summary: Optimize 'select count(*) from Table'
Key: IGNITE-7167
URL: https://issues.apache.org/jira/browse/IGNITE-7167
Project: Ignite
Issue Type: Improvement
Components: sql
Affects Versions: 2.3
Reporter: Valentin Kulichenko
Currently query like {{select count(*) from Table}} effectively scans the cache
and take a lot of time for large datasets. Probably makes sense to optimize it
to use {{IgniteCache#size}} directly when possible.
