> In case of large indexes, indexing takes a long time. In case of MongoDB Document store,
Currently it is a two step process - download the data from mongodb then create index based
on that data.
> If something fails during this process, indexing needs to be restarted from beginning
of the download step. We should make the indexing process resumable from the point it stopped. 
> Since data download from mongodb seems to be more time taking than indexing itself, we
first focus on download part. 
> This Jira issue is for implementing resumable/parallel download.
