[teiid-issues] [JBoss JIRA] Created: (TEIID-1474) Add query hint to limit parallel execution of union members

Add query hint to limit parallel execution of union members ----------------------------------------------------------- Key: TEIID-1474 URL: https://issues.jboss.org/browse/TEIID-1474 Project: Teiid Issue Type: Feature Request Reporter: Howard Abrams Assignee: Steven Hawkins 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.
