Bala Kolla resolved COUCHDB-3150.
---------------------------------
Resolution: Fixed
> Update all shards with stale=update_after
> -----------------------------------------
>
> Key: COUCHDB-3150
> URL: https://issues.apache.org/jira/browse/COUCHDB-3150
> Project: CouchDB
> Issue Type: Story
> Components: Database Core
> Reporter: Bala Kolla
>
> Stale=update_after should update shards that won't participate in the
> response due to not being a ushard.
> Discussed with Paul Davis and he suggested the following approach.
> For this ticket we should just need to add a
> fabric_view:maybe_update_others/3 that we call just after [1,2] with
> fabric_view:maybe_update_others(DbName, Shards, Args). And then if
> stable=true and update=(true or lazy) we do mem3:shards(DbName) --
> ShardsInvolved, and throw a message at them to trigger an update.
