    [ https://issues.jboss.org/browse/TEIID-3906?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13153177#comment-13153177 ] 

Ramesh Reddy commented on TEIID-3906:
-------------------------------------

I have added required code upstream towards Olingo 4.2.0 version, but I do not think this warrants a patch in the Teiid side, I am going to defer this until Teiid updates the Olingo library to 4.2.0

> Teiid does not process header *OData-Isolation: snapshot* defined in request correctly.
> * if service (Teiid) does not support this option it must return error 412
> * if Teiid does supports this option then it is not processed correctly, because modifications made during request are visbile
