[teiid-issues] [JBoss JIRA] Updated: (TEIID-1474) Add a limit to the number of concurrent source queries issued.

[ https://issues.jboss.org/browse/TEIID-1474?page=com.atlassian.jira.plugin... ] Steven Hawkins updated TEIID-1474: ---------------------------------- Summary: Add a limit to the number of concurrent source queries issued. (was: Add query hint to limit parallel execution of union members) Description: The default of allowing an unlimited number of concurrent source queries is not desirable in extreme situations. A limit should be added to prevent contention or other problems with issuing a large number of source queries. (was: We would like a new query hint to limit the number of parallel executions of union members. This is useful in two situations: 1. When the queries are expensive, but the overall union contains a limit that is most likely to be fulfilled by the first member of the union 2. When the queries are backed by a common resource which may be overloaded by multiple queries The addition of a hint would make this manageable by the client; perhaps something like "/*+ parallel=2*/"? ) updated to split into separate issues. -- This message is automatically generated by JIRA.
