Joel Bernstein updated SOLR-4465:
---------------------------------
Attachment: SOLR-4465.patch
Added the merge() method to the SumCollectorFactory. This adds the distributed
support for the proof of concept fot pluggable analytics using delegating
collectors.
Also changed the parameter spec to use ordinals to send parameters to the
correct collector. For example if three delegating collectors are specified as:
cl.delegating=sum,ave,min
The ordinals for the three collectors would be 0,1,2.
To pass parameters to sum collector factory you include the ordinal after the
"cl".
For example:
cl.0.groupby=manu
Tells the collector at ordinal 0 (sum) to groupby the manu field.
Also changed caching logic so that if delegating collectors are used
QueryResultCaching is turned off.
TODO:
Test, Test cases.
Update the Description of this ticket to include full specification.

> This issue is to add configurable custom collectors to Solr. This expands the
> design and work done in issue SOLR-1680 to include:
> 1) CollectorFactory configuration in solconfig.xml
> 2) Http parameters to allow clients to dynamically select a CollectorFactory
> and construct a custom Collector.
> 3) Make aspects of QueryComponent pluggable so that the output from
> distributed search can conform with custom collectors at the shard level.
