[jira] [Commented] (COUCHDB-3331) ETag not returned for GET against view

["Ondřej Novák (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/COUCHDB-3331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15978272#comment-15978272 ] 

Ondřej Novák commented on COUCHDB-3331:
---------------------------------------


Unfortunately this is WAI. CouchDB 2.0 no longer support ETags for views. I hope they find solution for this asap, because it degrades caching complete. As workaround you can use list function to emulate this feature since the list function can control what appears in the respone.

(And because it can be emulated, it should be easy to resolve this issue in future version)
