[JBoss JIRA] Created: (TEIID-1498) Incorrect rewrite of not disjunctive criteria

by Steven Hawkins (JIRA)

Incorrect rewrite of not disjunctive criteria ---------------------------------------------- Key: TEIID-1498 URL: https://issues.jboss.org/browse/TEIID-1498 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Critical Fix For: 7.4 The rewrite of a condition such as "not((a or b) AND c)" with a,b,c predicates where c a is predicate that is negatable, such as col1 = 1. The result should have the negated form of col1 <> 1, but instead has col1 = 1. This is because the col1 = 1 predicate is repeated in the result, but not cloned and the rewriter modifies the same instance. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1489) Teiid assumes fqns in transformations, but they are no longer required to be there

by Steven Hawkins (JIRA)

Teiid assumes fqns in transformations, but they are no longer required to be there ---------------------------------------------------------------------------------- Key: TEIID-1489 URL: https://issues.jboss.org/browse/TEIID-1489 Project: Teiid Issue Type: Bug Components: Query Engine Affects Versions: 7.1 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Critical Fix For: 7.4 It looks like with the uuid refactoring we no long maintain that the designer indexed transformations will contain only fully qualified group names. This will cause a good deal of problems at runtime as partially qualified names are subject to visibility rules and can conflict with session level tables. I would prefer to address this on the teiid though better metadata logic, rather than requiring fqns in transformation queries. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1473) Don't batch more rows than is needed when query contains limit but translator does not support limit

by Howard Abrams (JIRA)

Don't batch more rows than is needed when query contains limit but translator does not support limit ---------------------------------------------------------------------------------------------------- Key: TEIID-1473 URL: https://issues.jboss.org/browse/TEIID-1473 Project: Teiid Issue Type: Enhancement Reporter: Howard Abrams Assignee: Steven Hawkins Priority: Minor Teiid shouldn't try to batch more rows than is needed when query contains limit and translator does not support limit. For example, say there is a translator that exposes a table "A", but does not support limit. select * from A limit 2 will currently select an entire batch of rows (1024?) from A, instead of just stopping after 2 rows. Likewise, if the translator supports neither offset nor limit, and the query contains both, Teiid should not try to batch more that (offset + limit) rows. This is marked as "Minor" because the workaround of naively supporting limit and offset within a translator is not too hard. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1494) Allow the optional join hint to work with non-ansi joins

by Steven Hawkins (JIRA)

Allow the optional join hint to work with non-ansi joins -------------------------------------------------------- Key: TEIID-1494 URL: https://issues.jboss.org/browse/TEIID-1494 Project: Teiid Issue Type: Feature Request Components: Query Engine Affects Versions: 7.4 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4 The optional join hint currently works only in ansi joins, and then only if the table(s) are not used in where predicates forcing unnatural on clauses. e.g. select b.* from /*+optional*/ a, b where a.x = b.x should still allow a to be optional. -- This message is automatically generated by JIRA.

[JBoss JIRA] Created: (TEIID-1493) In a cluster the distributed cache is cleared by a node rejoining

by Steven Hawkins (JIRA)

In a cluster the distributed cache is cleared by a node rejoining ----------------------------------------------------------------- Key: TEIID-1493 URL: https://issues.jboss.org/browse/TEIID-1493 Project: Teiid Issue Type: Quality Risk Components: Query Engine Affects Versions: 7.1 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4 The load event for a vdb (even startup) will trigger a clearing of the cache, which when clustered will include the distributed entries. In a clustered mode we assume (and should possibly enforce) that vdb versioning must be used to differentiate vdbs so it should be safe to not clear the replicated area. -- This message is automatically generated by JIRA.
