Joel Bernstein updated SOLR-16524:
----------------------------------
Description:
Both Streaming Expressions and Spark-Solr currently rely on query time hash
partitioning using the HashQParserPlugin. The query time hash partitioning,
although extremely flexible, is very slow when it build its initial filters.
This ticket will add an indexing time hash partitioner that Streaming
Expressions and Spark-solr will both be able to use.
When this ticket is complete I'll also update the ParallelStream and Spark-Solr
to be able to use the index time partitioning rather than the HashQParserPlugin.
This is a stepping stone towards much more performant parallel distributed
joins.
