      Description

      We are seeing services responding poorly - UI freeze, Rest APIs having a higher latency when there are a lot of flowlets accessing datasets (600+ flowlets).

      There are a couple of things that are not ideal - several RPC calls for a single request to fetch dataset (3 Transaction RPC, 3 Scans). The guice modules are instantiated on every request.

      Need to figure out the early wins for 3.0.0
