[jira] [Commented] (COUCHDB-1367) update_seq does not always
reflect the seq of the latest document update
[ https://issues.apache.org/jira/browse/COUCHDB-1367?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13177798#comment-13177798 ]
Robert Newson commented on COUCHDB-1367:
----------------------------------------
I still don't see why we need do anything. My early mistaken understanding of this value should not be used as motivation here. At the time, I was not a "couchdb committer" so the earlier implication that it escaped even my awesome knowledge is to impute omniscience where none is warranted.
I haven't yet fixed couchdb-lucene as the update model is rather clumsy. Simply calling _changes?since=N instead of comparing update_seq with a local value will radically simplify that piece of couchdb-lucene. It should improve the internals of couchdb-lucene so significantly that I would rather *not* fix update_seq to work the way I expected years ago, in case it misleads someone into making the same mistake I made.
That said, I wouldn't veto the change, but C-L will not depend on either the current or any future meaning of update_seq in the next release.

> Priority: Minor
> Labels: revs_limit

> Certain operations, (currently _revs_limit and _security changes) cause the database header's update_seq to increase when the by_seq index (and therefore _changes) has not changed, which is confusing in light of the naming consistency.

That was my oversight. Please forgive the error.
