[teiid-issues] [JBoss JIRA] (TEIID-4213) Cassandra translator: enable pushdown of aggregate functions

Steven Hawkins commented on TEIID-4213:
---------------------------------------
Since aggregate functions weren't added until 2.2, it would be best to have the
support marked as conditional - or update the admin guide to state that it's our
minimum expected server version.
It also looks like we're due for a client driver upgrade, as even our version
detection logic wouldn't work in this case as we are using the 2.1 client.
Cassandra translator: enable pushdown of aggregate functions
------------------------------------------------------------
Key: TEIID-4213
URL: https://issues.jboss.org/browse/TEIID-4213
Project: Teiid
Issue Type: Feature Request
Components: Misc. Connectors
Affects Versions: 8.12.x
Reporter: Jan Stastny
Assignee: Ramesh Reddy
Priority: Minor
Fix For: 9.1
Cassandra supports basic aggregate functions:
MIN(),MAX(),SUM() and AVG()
Currently Teiid doesn't push such queries.
NOTE:In case of AVG() there is difference between the values returned from Teiid vs.
Cassandra for an integer column. Cassandra returns only whole part of the number as
integer, Teiid returns bigdecimal.
