Steven Hawkins resolved TEIID-2790.
-----------------------------------
Resolution: Done
Marking as done for now. There is additional work to be done to add column costing
information and to make this a post import activity, but that will come later.
Add more options for costing during import
------------------------------------------
Key: TEIID-2790
URL: https://issues.jboss.org/browse/TEIID-2790
Project: Teiid
Issue Type: Feature Request
Components: JDBC Connector, Misc. Connectors
Reporter: Steven Hawkins
Assignee: Steven Hawkins
Fix For: 8.7
With many jdbc sources full cardinality is reported from the index info for non
statistical indexes (such as mysql). This should be used to set the cardinality of the
table. Failing that there should be an option to use an aggregate call or other source
stats.
This is not quite the same as TEIID-245 as it's happening at import time, but the two
do overlap.
