Hi Srikanth As RocksDB is a single node DB which just like InfluxDB, I recommend you could refer to an implementation of InfluxDB sink. [1]

Here[1] we have a brief wiki to show what interfaces we need to implement, but seems it's not detailed enough personally. I think the existed kafka connector code will be helpful for implementing your RocksDB sink [2].

Context: I get a list of IPaddresses in a stream which I wish to store in RocksDB. Therefore the other stream perform a lookup to match the IPaddress. Thanks Srikanth
