Johnathon Lee created TEIID-2337: ------------------------------------ Summary: Source Hints documenation states source hints can be used in user and transformation queries Key: TEIID-2337 URL: https://issues.jboss.org/browse/TEIID-2337 Project: Teiid Issue Type: Bug Components: JDBC Driver, Query Engine Affects Versions: 8.2, 7.7.2 Reporter: Johnathon Lee Assignee: Johnathon Lee Per [1], 15.2.13.4 states that user queries can contain source hints. Using hints in transformations as follows [2], I can see the HINT being passed to source. Using a SQL client such as SQuirreL and the Teiid Driver the START USER COMMAND does not show the HINT being passed in. [1] https://access.redhat.com/knowledge/docs/en-US/JBoss_Enterprise_Data_Serv... [2] I have completed a few steps in order to verify the source hint can be passed along using a test vdb (bqt using SLNTDS08.mw.lab.eng.bos.redhat.com). Created a view (SourceView.SMALLA) with the transformation [1a]. Note that there seems to be an issue with designer recognizing the format of the hint in the SQL statement and discarding (which is why the /*+sh:'general hint' has been included). Note that "Source:" is the Source Name specified by the Translator (this can be seen when viewing the vdb in designer). Turned up the logging to trace for org.teiid in the logging subsystem [2a]. Verified via the logging that the hint is being passed to the source system [3a] [1a] SELECT /*+sh:'general hint' Source:'FIRST_ROWS(10)' */ * FROM Source.SmallA [2a] ... <logger category="org.teiid"> <level name="TRACE"/> </logger> ...
