Subject [jira] Commented: (COUCHDB-218) Name view files by function signature for no-downtime deployments
Date Fri, 19 Jun 2009 17:08:07 GMT

    [ https://issues.apache.org/jira/browse/COUCHDB-218?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12721882#action_12721882

Chris Anderson commented on COUCHDB-218:
----------------------------------------

as long as we're in there optimizing this stuff, we should make sure that the ddoc signature
is generated the same regardless of the order of the views in the JSON document. this should
be just a matter of sorting before taking the signature. it will prevent us from invalidating
indexes that are actually valid.

> When a view is altered the .view file is deleted and then recreated. Any query (with
update=false) in the interim gets no results even though the results from the old view would
have been adequate.
> Consider switching the replacement view file in after it's been rebuilt like db compaction
does.
