James Dyer commented on SOLR-2549:
----------------------------------
The dependency here to SOLR-2943 is only for the "DIHCacheTypes" enum, which
defines data types for each flat file column of data. This is particularly
helpful when joining to SQL data sources as DIH requires the join keys be the
same type. It might be beneficial to rename the enum to "DIHType" or something
more generic, should either issue become a candidate for commit.
