[JBoss JIRA] (TEIID-2843) MongoDB: ClassCastException while doing JOIN based query

by Ramesh Reddy (JIRA)

[ https://issues.jboss.org/browse/TEIID-2843?page=com.atlassian.jira.plugin... ] Ramesh Reddy resolved TEIID-2843. --------------------------------- Labels: Alpha3 mongodb (was: mongodb) Resolution: Done This was simply a coding error. I previously assumed that in muti-table JOIN scenario command always opens up LEFT side a JOIN and right as leaf.

[JBoss JIRA] (TEIID-2845) MongoDB: Join processing produces wrong results in some cases

by Ramesh Reddy (JIRA)

[ https://issues.jboss.org/browse/TEIID-2845?page=com.atlassian.jira.plugin... ] Ramesh Reddy resolved TEIID-2845. --------------------------------- Labels: alpha3 mongodb (was: mongodb) Resolution: Done The $unwind operator behavior was wrongly assumed, where the empty child documents did not produce any documents, so all joins were behaving as INNER joins. See related discussion on it https://groups.google.com/forum/#!topic/mongodb-user/UKYPddRN37E Used the workaround mentioned on this thread, so that Teiid can generate * INNER JOIN * LEFT [OUTER] JOIN (left is assumed to be the parent document) * CROSS JOIN will be handled by the Teiid engine, as the JOIN capabilities define they only work on KEY based. * RIGHT OUTER JOIN either re-written based on which side is parent, otherwise this JOIN produces an exception. One possibility is to extend the "allow-join" semantics to define such that "RIGHT JOIN" is not supported, in which case it can be handled in Teiid query engine. > MongoDB: Join processing produces wrong results in some cases > ------------------------------------------------------------- > > Key: TEIID-2845 > URL: https://issues.jboss.org/browse/TEIID-2845 > Project: Teiid > Issue Type: Bug > Components: Misc.

[JBoss JIRA] (TEIID-2728) Very large sorts are inefficient

by RH Bugzilla Integration (JIRA)

When the memory space needed for a sort is estimated to be above 2 GB, the expression used (even though it's assigned to a long) will overflow. This then causes the processing to use the batch size as the intermediate sort buffer size, which for any high row count will lead to many passes (the logic typically should achieve at most a two pass sort). -- This message is automatically generated by JIRA.

[JBoss JIRA] (TEIID-2690) Tuples lost in a with clause item.

Thus may occur as a somewhat rare timing issue in 8.3.x+. However in 7.7.7/7.7.8 a single block cause the recreation of the BatchIterator making the affect almost certain once the row count exceeds the computed working batch size (nominally 256 rows, but allowed to vary based upon the row width). -- This message is automatically generated by JIRA.
