Juraj Duráni created TEIID-4694:
-----------------------------------
Summary: PrestoDB tranlator - NULL values not supported in SemiJoin
Key: TEIID-4694
URL: https://issues.jboss.org/browse/TEIID-4694
Project: Teiid
Issue Type: Bug
Components: Query Engine
Affects Versions: 8.12.8.6_3
Reporter: Juraj Duráni
Assignee: Steven Hawkins
PrestoDB does not allows NULL values in SemiJoin operator. It means, that query like \[1\]
causes an exception \[2\]. However, this is disallowed in version 0.162 but worked in
0.161. According to GitHub issues \[3\], this will be fixed in one of the future versions
of PrestoDB. Do we want to handle it somehow?
Development and release frequency of PrestoDB seems to be pretty fast (new release every 2
or 3 week).
