------------------------------------------
Summary: Optimise byte array to hex string conversion
Key: CASSANDRA-20724
URL: https://issues.apache.org/jira/browse/CASSANDRA-20724
Project: Apache Cassandra
Issue Type: Improvement
Reporter: Archit Agarwal
Assignee: Archit Agarwal
Current implementation of converting byte array to hex string uses string
formatting which needs to parse the format ("%02x") for every byte. This takes
a lot of time and CPU.
{code:java}
"0x" + x.map("%02x" format _).mkString{code}
Change to standard way using bit operations drastically increases the
performance.
