C. Scott Andreas updated CASSANDRA-11622:
-----------------------------------------
Component/s: CQL
> Optimize native protocol result set serialization format
> --------------------------------------------------------
>
> Key: CASSANDRA-11622
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11622
> Project: Cassandra
> Issue Type: Improvement
> Components: CQL
> Reporter: Sylvain Lebresne
> Priority: Major
> Labels: client-impacting, protocolv5
>
> The format in which result sets are serialized in the native protocol has the
> advantage of being very simple (which was, initially, a feature), but it
> isn't very optimal. It's probably now time to think about optimizing it
> further.
> At the very least, there is 2 simple optimizations we can do:
> # we can avoid the repetition of partition key columns (as well as duplicate
> clustering column value when we have more than one clustering column, though
> we'd have to recompute this at the CQL level since we don't have this
> "optimization" internally (yet at least), contrarily to the partition key
> case).
> # we can optimize the serialization of value of fixed-width type (like we now
> do internally) by skipping the current 4 byte length. We could also maybe use
> vints for the remaining case where there is a length.
> But of course, it's worth considering other potential optimization while
> we're at it.
