Jeff Jirsa commented on CASSANDRA-13476:
----------------------------------------

{quote} how can we support all the CQL semantics (like collections, clustering, TTL, LWT,
SASI, MV, UDF/UDA ...) {quote}

[~doanduyhai] - for clustering, there's a blocking sub-ticket specifically addressing it CASSANDRA-13553

> As I mentioned in CASSANDRA-13474, we got huge P99 read latency gain from the RocksDB
integration experiment.
> After we make the existing storage engine to be pluggable, we want to implement a RocksDB
based storage engine, which can support existing Cassandra data model, and provide better
and more predictable performance.
> The effort will include but not limited to:
> 1. Wide column support on RocksDB
> 2. Streaming support on RocksDB
> 3. RocksDB instances management
> 4. Nodetool support
> 5. Metrics and monitoring
> 6. Counter support on RocksDB
