[JBoss JIRA] Created: (TEIID-1463) limit buffering for large results

by Steven Hawkins (JIRA)

limit buffering for large results --------------------------------- Key: TEIID-1463 URL: https://issues.jboss.org/browse/TEIID-1463 Project: Teiid Issue Type: Feature Request Components: Query Engine Affects Versions: 7.0 Reporter: Steven Hawkins Assignee: Steven Hawkins In a forward only scenario, if a client lags behind the server a buffer will still be built containing much of result. It would be good to limit the buffer size and prempt proactive processing when exceeded. -- This message is automatically generated by JIRA. - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-946) add support for in/out out return params

by Steven Hawkins (JIRA)

add support for in/out out return params ---------------------------------------- Key: TEIID-946 URL: https://jira.jboss.org/jira/browse/TEIID-946 Project: Teiid Issue Type: Feature Request Components: Query Engine Affects Versions: 8.0 Reporter: Steven Hawkins Assignee: Steven Hawkins Priority: Minor Fix For: 8.0 In/out, out, return parameters should be supported in Teiid defined procedures - not just result sets. The logic for handling them would be similar to what exists for managing the update_count variable. The Designer would also need to remove validation restrictions preventing the usage of these parameters. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-1329) API to force metadata read

by Mark Addleman (JIRA)

API to force metadata read -------------------------- Key: TEIID-1329 URL: https://jira.jboss.org/browse/TEIID-1329 Project: Teiid Issue Type: Feature Request Components: AdminApi Affects Versions: 7.1 Reporter: Mark Addleman Assignee: Steven Hawkins Priority: Minor We have a dynamic set of datasources that are accessed through Teiid. Each data source is represented as a different model within the VDB. Some data sources may not be available at the time Teiid executes the translator's getMetadata() method. When our code detects the data source is available, I'd like to poke Teiid to re-read the appropriate translator's metadata. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-1509) Change the default for value caching

by Steven Hawkins (JIRA)

Change the default for value caching ------------------------------------ Key: TEIID-1509 URL: https://issues.jboss.org/browse/TEIID-1509 Project: Teiid Issue Type: Quality Risk Components: Query Engine Affects Versions: 7.4 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4 There is a larger performance impact from having value caching enabled with large data sets (which is the more typical deployment scenario) than having value caching disabled and a larger memory footprint. So the value caching default should change to false. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira

[JBoss JIRA] Created: (TEIID-1481) client url cleanups

by Steven Hawkins (JIRA)

client url cleanups ------------------- Key: TEIID-1481 URL: https://issues.jboss.org/browse/TEIID-1481 Project: Teiid Issue Type: Task Components: JDBC Driver Affects Versions: 7.4 Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4 Designer is now leveraging the TeiidURL class for validation of server urls. The messages need internationalized and it would be better to through a checked exception (such as MalformedUrlException) rather than IllegalArgumentException. In addition there is a lot of redundancy with url handling in the Socket/EmbeddedProfile, JDBCURL, and TeiidDataSource. This should be consolidated as much as possible. -- This message is automatically generated by JIRA. For more information on JIRA, see: http://www.atlassian.com/software/jira

RulePushAggregates should consider cost in addition to key information ---------------------------------------------------------------------- Key: TEIID-1510 URL: https://issues.jboss.org/browse/TEIID-1510 Project: Teiid Issue Type: Feature Request Components: Query Engine Reporter: Steven Hawkins Assignee: Steven Hawkins Fix For: 7.4 RulePushAggregates currently only considers whether a key is in use in the grouping columns to not stage an aggregate. It should additionally use a cost check to see if the staged aggregate is cost effective. -- This message is automatically generated by JIRA.
