DIH delta import with cache 5.3.1 issue

[Sujay Bawaskar]

Hi,

We are using DIH with cache(SortedMapBackedCache) with solr 5.3.1. We have
around 2.8 million documents in solr and total index size is 4 GB. DIH
delta import is dumping all values of mapped columns to their respective
multi valued fields. This is causing size of one solr document upto 2 GB.
Is this a known issue with solr 5.3.1?

Thanks,
Sujay
