Externally load data into RocksDB backend

[Arpith P]

Hi,

Is it possible to load data to RocksDB backend externally(outside Flink )
using  common dbPath, so that it will be available to MapState inside
ProcessFunction. I've external data available in JSON format which I want
to load to RocksDb. One option is to make Stream from the JSON path and
process it inside ProcessFunction but since I can't modify existing
ProcessFunction ;I'm thinking of alternate ways of doing it.

Thanks,
Arpith
