Daniel Norberg created CASSANDRA-4710: -----------------------------------------
Summary: High key hashing overhead for index scans when using RandomPartitioner Key: CASSANDRA-4710 URL: https://issues.apache.org/jira/browse/CASSANDRA-4710 Project: Cassandra Issue Type: Bug Reporter: Daniel Norberg For a workload where the dataset is completely in ram, the md5 hashing of the keys during index scans becomes a bottleneck for reads when using RandomPartitioner, according to profiling. Instead performing a raw key equals check in SSTableReader.getPosition() for EQ operations improves throughput by some 30% for my workload (moving the bottleneck elsewhere). -- This message is automatically generated by JIRA.
