---------------------------------------
Summary: Clarify "collocated" flag documentation
Key: IGNITE-12382
URL: https://issues.apache.org/jira/browse/IGNITE-12382
Project: Ignite
Issue Type: Bug
Components: documentation
Affects Versions: 2.7.6
Reporter: Denis A. Magda
Assignee: Artem Budnikov
Fix For: 2.8
Documentation of the JDBC and ODBC drivers doesn't explain when and why the
"collocated" flag needs to be set. The docs are vague and not clear:
https://apacheignite-sql.readme.io/docs/jdbc-driver
https://apacheignite-sql.readme.io/docs/connection-string-and-dsn
In fact, the optimization is useful for queries with GROUP BY operand. The docs
need to be improved with the content of the Javadoc and a summary shared in the
dev list discussion:
https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/cache/query/SqlFieldsQuery.html#isCollocated--
http://apache-ignite-developers.2346864.n4.nabble.com/Collocated-replicatedOnly-flags-for-Thin-JDBC-driver-td44357.html
