> @mridulm There is no full prototype. I will send out a PR 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 [4274fb8#diff-0cd94c36f45f50f513aeda6504fda0545270b05e105191131b601eb12b8a656bR42](https://github.com/apache/spark/commit/4274fb8806c25519cac829d00b01132fe08c0cac#diff-0cd94c36f45f50f513aeda6504fda0545270b05e105191131b601eb12b8a656bR42) @gengliangwang Have you compared `Protobuf` and `Flatbuffers`? From the official benchmark data, `Flatbuffers` may have better performance. http://google.github.io/flatbuffers/flatbuffers_benchmarks.html -- This is an automated message from the Apache Git Service.
