Ivan Chan created TEIID-2722: -------------------------------- Summary: Cassandra: ORDER BY should do it in memory instead of trying to push down Cassandra in some cases Key: TEIID-2722 URL: https://issues.jboss.org/browse/TEIID-2722 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 8.6 Environment: Teiid 8.6 Alpha with Cassandra 1.2.11 Reporter: Ivan Chan Assignee: Steven Hawkins When I tried to join 2 tables together from same keyspace using Teiid 8.6 Alpha with Cassandra 1.2.11. It broke down SQL into 2 CQLs. However, teiid SQL transformer adds order by clause to the CQL which is not supported. Original SQL: select "cassandraDS_users"."user_id" as "cassandraDS_users_user_id", "cassandraDS_invoice"."sale" as "cassandraDS_invoice_sale" from "cassandraDS"."invoice" "cassandraDS_invoice" inner join "cassandraDS"."users" "cassandraDS_users" on ("cassandraDS_invoice"."user_id" = "cassandraDS_users"."user_id") Break Down CQL: SELECT cassandraDS.invoice.user_id, cassandraDS.invoice.sale FROM cassandraDS.i nvoice ORDER BY cassandraDS.invoice.user_id SELECT cassandraDS.users.user_id FROM cassandraDS.users ORDER BY cassandraDS.us ers.user_id Error from CQL Driver: com.datastax.driver.core.exceptions.InvalidQueryException: ORDER BY is only supported when the partition key is restricted by an EQ or an IN. -- This message is automatically generated by JIRA.
