And there's an open issue where this sort of feature can be contributed: https://issues.apache.org/jira/browse/SOLR-903

Though in that issue there are a two different approaches mentioned, one being purely SolrJ client-side (my original intention in opening the issue), but also what Mark mentions on the server side to allow update requests to be logged completely.

Thanks Mark.  That's sort of what I was thinking of doing.

1. A document repository that fires events (containing a URL) when new

I'm looking at ~200M documents for the initial launch, with around 30K new
docs every day, and many thousands of metadata events every day.

Do any of you Solr gurus have any suggestions or guidance you can share

me?

Thanks in advance,

Pump everything through an UpdateProcessor that writes out SolrXML as docs
go by?
