This looks super cool would love to see more details. On a general note, a pluggable storage layer allows other storage engines (and possibly datastores) to leverage Cassandras distributed primitives (dynamo, gossip, paxsos?, drivers, cql etc). This could allow Cassandra to fill similar use cases

There is probably something I missed the message below. In my experience with pluggable storage engines (in the MySQL world), the engine manages all storage that it "owns." The higher tiers in the architecture don't need to get involved unless multiple storage engines have to deal with

"I have no clue what it would take to accomplish a pluggable storage engine, but I love this idea." This was a long and old debate we had several times in the past. One of the difficulty of pluggable storage engine is that we need to manage the differences between the LSMT of native C* and RockDB

We should definitely evaluate pluggable storage engine...Besides several other advantages, it also helps in adding lot of tests to the storage engine. On Wed, Apr 19, 2017 at 11:22 AM, Jon Haddad wrote: > I have no clue what it would take to accomplish a pluggable

I have no clue what it would take to accomplish a pluggable storage engine, but I love this idea. Obviously the devil is in the details, & a simple K/V is very different from supporting partitions, collections, etc, but this is very cool & seems crazy not to explore further. Will you be

Hi Cassandra developers, This is Dikang from Instagram, I'd like to share you some experiment results we did recently, to use RocksDB as Cassandra's storage engine. In the experiment, I built a prototype to integrate Cassandra 3.0.12 and RocksDB on single column (key-value) use case, shadowed one
