Mikhail Khludnev updated SOLR-4799:
-----------------------------------
Attachment: SOLR-4799.patch
improved test coverage in TestSqlEntityProcessor* :
- added countries into zipper join
- added more entropy into data (orphans, and childfree)
- improved few asserts, made them randomized and mandatory
[~jdyer] improved tests are worth to consider, beside of this jira

> DIH is mostly considered as a playground tool, and real usages end up with
> SolrJ. I want to contribute few improvements target DIH performance.
> This one provides performant approach for joining SQL Entities with miserable
> memory at contrast to
> http://wiki.apache.org/solr/DataImportHandler#CachedSqlEntityProcessor
> The idea is:
> * parent table is explicitly ordered by it’s PK in SQL
> * children table is explicitly ordered by parent_id FK in SQL
> * children entity processor joins ordered resultsets by ‘zipper’ algorithm.
> Do you think it’s worth to contribute it into DIH?
