Steven Hawkins commented on TEIID-4021:
---------------------------------------
That is expected behavior. It is assumed that a given translator is talking to a single
database type/version. In a heterogeneous case you will need to manually set the database
version property on the executionfactory to the lowest version.

Key: TEIID-4021
URL:
https://issues.jboss.org/browse/TEIID-4021
Project: Teiid
Issue Type: Enhancement
Components: JDBC Connector
Reporter: Mark Tawk
Assignee: Steven Hawkins
Fix For: 9.1
I'm using Teiid 8.11.3 with mssql translator.
I have a huge table over sql server 2008 on which i'm applying pagination.
I noticed slowliness in the query execution over this table at each time I increase the
pagination.
I monitored the JDBC queries execute by teiid and found out that it is using top n
according to the limit used into the query.
For example:
in teiid : Select * from mytable LIMIT 90 , 10
is translated in JDBC: select top 100 from mytable
Since my table contains millions of records, when fetching the last page, the executed
jdbc query is retrieving the whole table top n, to return in result the last 10 records.
And the execution is taking too much time.
