Steven Hawkins resolved TEIID-4711.
-----------------------------------
Resolution: Done
Updated the docs around IS DISTINCT FROM with a warning about non-pushdown performance
when used as a join predicate.
ILIKE/IREGEXP/RLIKE functions were added to the translator, which are visible when using
the native metadata or the designer import option to import pushdown functions.
We should consider adding engine support for ILIKE/ILIKE_REGEX as well even though they
haven't been standardized yet.
Add multiple operator supports to Impala translator (case insensitive
ilike, iregex, etc))

Key: TEIID-4711
URL: https://issues.jboss.org/browse/TEIID-4711
Project: Teiid
Issue Type: Feature Request
Components: JDBC Connector
Affects Versions: 9.1.1
Reporter: Don Krapohl
Assignee: Steven Hawkins
Labels: Impala_Translator
Fix For: 10.0
Per https://www.cloudera.com/documentation/enterprise/5-8-x/topics/impala_ope...
Impala post-2.5 supports several operations that should be pushed down.
As a user I would like to be able to use the following SQL operations and have them
pushed down in my queries using the Impala translator:
ILIKE
IREGEXP
IS DISTINCT FROM
RLIKE
