[ https://issues.jboss.org/browse/TEIID-5809?page=com.atlassian.jira.plugin... ] Steven Hawkins commented on TEIID-5809: --------------------------------------- It's for change data capture. If a source does not expose delta functionality, you need something to capture when and what is changing. The support in olingo is to just provide the parsed query option - they have no processing logic on their notion of Entity. The Teiid logic would have to look for the delta tokens and see if the Entities included the appropriate modification properties/procedures - which would require either a name/type based convention and/or extension metadata. Note that Salesforce exposes similar information via audit fields on each sObject and a procedure to find what has been deleted, so finding the deleted information will vary by backend. Not that I'm aware of. -- This message was sent by Atlassian Jira (v7.13.5#713005)
