Steven Hawkins created TEIID-2356: ------------------------------------- Summary: CLONE - Add a query hint to limit the number of concurrent source queries Key: TEIID-2356 URL: https://issues.jboss.org/browse/TEIID-2356 Project: Teiid Issue Type: Sub-task Components: Query Engine Affects Versions: 7.4 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Minor 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*/"? -- This message is automatically generated by JIRA.
