-------------------------------------
Summary: Add support for 'Union All' flow in Oql
Key: GEODE-4041
URL: https://issues.apache.org/jira/browse/GEODE-4041
Project: Geode
Issue Type: New Feature
Components: querying
Reporter: Dharam Thacker
There are lot of applications in Financial services world driven by 'Lookup
based rules'/'Decision Table' approach.
*+Example:+*
Give me all rules where counterParty matches to "XYZ" and Products matches
"INDEX|TRANCHE" and clearingJurisdictions matches "ICE|ESMA"
UNION ALL
Give me all rules where counterParty matches to "XYZ" and Products matches
"ALL" and clearingJurisdictions matches "ALL"
Purpose of above query is to get either exact rule/default rule which is a
super set of given trade facts.
As of now, one has to write function logic to deal with such situations to
avoid round trip between client/server due to invocation of multiple queries
