This patch adds initial support for PREPARE and EXECUTE requests which are used by the CQL binary protocol for prepared statements. The use of prepared statement gives a nice 2.5x single core performance boost for Urchin: $ ./build/release/seastar --data data --smp 1 $ ./tools/bin/cassandra-stress write -mode cql3 simplenative -rate threads=32 Results: op rate : 31728 partition rate : 31728 row rate : 31728 latency mean : 1.0 latency median : 0.9 latency 95th percentile : 1.8 latency 99th percentile : 1.8 latency 99.9th percentile : 5.6 latency max : 181.7 Total operation time : 00:00:30 END $ ./tools/bin/cassandra-stress write -mode cql3 simplenative prepared -rate threads=32 Results: op rate : 75033 partition rate : 75033 row rate : 75033 latency mean : 0.4 latency median : 0.4 latency 95th percentile : 0.7 latency 99th percentile : 0.8 latency 99.9th percentile : 3.4 latency max : 205.0 Total operation time : 00:00:30 END Signed-off-by: Pekka Enberg <penberg@cloudius-systems.com>
