Hoss Man commented on SOLR-3215:
--------------------------------
I think this is still pretty damn important:
1) nothing stops people from putting other processors between
DistributeUpdateProcessorFactory and RunUpdateProcessorFactory
2) several use cases identified above are simpler (or *require*) putting
processors between DistributeUpdateProcessorFactory and
RunUpdateProcessorFactory
3) any processor put between DistributeUpdateProcessorFactory and
RunUpdateProcessorFactory is a time bomb of unpredictability w/o some sort of
cloning.
> We should clone the SolrInputDocument before adding locally and then send
> that clone to replicas.

> If we don't do this, the behavior is a little unexpected. You cannot avoid
> having other processors always hit documents twice unless we support using
> multiple update chains. We have another issue open that should make this
> better, but I'd like to do this sooner than that. We are going to have to end
> up cloning anyway when we want to offer the ability to not wait for the local
> add before sending to replicas.
> Cloning with the current SolrInputDocument, SolrInputField apis is a little
> scary - there is an Object to contend with - but it seems we can pretty much
> count on that being a primitive that we don't have to clone?
