Joel Bernstein updated SOLR-6398:
---------------------------------
Description:
This ticket builds on the existing AnalyticsQuery / MergeStrategy framework by
adding the abstract class IterativeMergeStrategy, which has built-in support
for call-backs to the shards. The IterativeMergeStrategy is designed to support
the execution of Parallel iterative Algorithms, such as Gradient Descent,
inside of Solr.
To use the IterativeMergeStrategy you extend it and implement process(). This
gives you access to the callback() method which makes it easy to make repeated
calls to all the shards and run algorithms that require iteration.
