[ https://issues.jboss.org/browse/TEIID-3491?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-3491: --------------------------------------- Because they are thread safe, we may look at using a more global pattern cache. For pushdown support it does look like we'll have to be careful. Many of the other implementations appear to replace all by default, have support for different or no flags, and the have variations in the regex syntax as you highlight with the back references. More than likely this means we'll need to add a method where the translator can be asked if it supports a given pattern. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
