DIH parallel processing

[nabil Kouici]

Hi All,
I'm using DIH to index more than 15M from Sql Server to Solr. This take more 
than 2 hours. Big amount of this time is consumed by data fetching from 
database. I'm thinking about a solution to have parallel (thread) loud in the 
same DIH. Each thread load a part of data.
Do you have any experience with this kind of situation?
Regards,Nabil.
