Hoss Man commented on SOLR-2894:
--------------------------------
bq. If a shard never responds, does the searcher handle that by eventually
timing out?
Off the top of my head i'm not sure -- i'm pretty sure that will generate an
error at a much lower level then the individual search components, so it's not
something the pivot code needs to worry about.
I think the main thing is that when the pivot codes is looking at a
ShardResponse, it should be able to say "this response doesn't contain a count
for the refinementX we asked for in the corrisponding ShardRequest, fail!" (as
opposed to know where i believe it reQueues it) ... we can leave worrying about
whether or not a ShardResponse was ever returned at all to the SearchHandler.
bq. ... I think we have the requisite accounting already in place to be able to
check if a shard did not respond with all the refinement values we asked for.
We should be able to check the refinements and see that they have had data
contributed from the shard in question, if not well throw an error.
that should be all we need.
