------------------------------------
Hi all,
I stumbled over this Jira issue today when I was searching for information to
explain some strange behavior in our implicit routed collection. We do
deleteById requests without adding a router.field value as we often do not have
that information at hand. We use commitWithin=30000 for our deleteById
requests. However, this always fails for documents of all replicas of one of
our two shards. The documents never get deleted. However, if we set
commitWithin to a very small value, the deleteById request propagates to all
shards and the documents get deleted.
I'm not sure whether there was a fix for the implicit router deleteById without
router.field value, but that behavior seems to me like (another) bug?

> A deleteById request without __route__ param for implicit router could be
> sent to all shard leaders (Shalin). Alternatively, a new router (or a strict
