[teiid-issues] [JBoss JIRA] (TEIID-5473) Make JDBCMetadataProcessor more extensible with protected methods

Ken Geis commented on TEIID-5473:
---------------------------------
I'm using the Oracle driver.
I just sampled (n=1) and found that without {{-DuseFetchSizeWithLongColumn=true}}, it
takes 2m48s. With it, it takes 2m11s. I'm not comfortable setting this property
application-wide, but I think it could be [set on the individual
connection|https://docs.oracle.com/javase/8/docs/api/java/sql/Connection....]
if I override {{process(..)}} or {{getConnectorMetadata(..)}}.
Yes, I can now see a path for trying a different Oracle-specific method for fetching index
information by returning false in {{getIndexInfoForTable}} and then using my own logic in
the overridden {{getConnectorMetadata(..)}}. If you have any hesitation in modifying the
API per my request, let me test out my hypothesis first.
Make JDBCMetadataProcessor more extensible with protected methods
-----------------------------------------------------------------
Key: TEIID-5473
URL: https://issues.jboss.org/browse/TEIID-5473
Project: Teiid
Issue Type: Feature Request
Components: JDBC Connector
Affects Versions: 11.1
Reporter: Ken Geis
Assignee: Steven Hawkins
Fix For: 11.2
I believe I can write a JDBCMetadataProcessor that works faster against my Oracle
database. The important part to override is in getIndexes(..). This method is
package-private, so I cannot override it. It would be useful to me if the method (and
maybe others) were made protected so that they can be overridden.
