Jason Rutherglen commented on SOLR-1477:
----------------------------------------
The way the process should work for this patch is:
1) Incoming query to shard proxy server
2) getids passed to N intermediary proxy servers
3) Intermediary proxy servers forwards the getids call to Y Solr servers
4) Y Solr servers respond, i-proxy merges the ids, and sends the response to
the toplevel proxy server from step 1)
5) The toplevel proxy merges the results from the i-proxies
6) getdocs is passed from proxy 1) to the i-proxies
7) i-proxies call Solr servers to obtain documents (the actual shard the
documents exist on needs to be passed to the i-proxy to avoid redundancy)
8) iproxies send the results of getdocs to the toplevel proxy
9) The request is completed.
I know that's muddy but it's a start.
