----------------------------------------
{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
> RocksDB based storage engine
> ----------------------------
>
> Key: CASSANDRA-13476
> URL: https://issues.apache.org/jira/browse/CASSANDRA-13476
> Project: Cassandra
> Issue Type: New Feature
> Reporter: Dikang Gu
>
> 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
