@mridulm There is no full prototype. I will send out a PR very soon. I did some benchmarks, it showed using Protobuf as serialization can speed up the read/write 3~4 times compared to the current implementation. Thus, we can use RocksDB as the storage layer, similar to the current `InMemoryStore`. I have to revert this one for removing the duplicated `diskStore` in https://github.com/apache/spark/commit/4274fb8806c25519cac829d00b01132fe08c0cac#diff-0cd94c36f45f50f513aeda6504fda0545270b05e105191131b601eb12b8a656bR42 -- This is an automated message from the Apache Git Service.
