[ https://issues.jboss.org/browse/TEIID-245?page=com.atlassian.jira.plugin.... ] Steven Hawkins commented on TEIID-245: -------------------------------------- Another more pervasive approach to consider would be stream sampling based upon query results.

However with metadata updates being non-persistent by default and possible performance issues with initial queries that would be a lower priority solution than simply being able to import source system statistics. -- This message is automatically generated by JIRA.
