absurdfarce pushed a commit to branch 4.x
in repository https://gitbox.apache.org/repos/asf/cassandra-java-driver.git
commit d0a1e44a4415c7a0489f8c35ee9ce49e20d7bc61
Author: Benoit Tellier <btell...@linagora.com>
AuthorDate: Sun Jan 22 13:58:19 2023 +0700
Limit calls to Conversions.resolveExecutionProfile
Those repeated calls account for a non-negligible portion of my application
CPU (0.6%) and can definitly be a final field so that it gets resolved only
once per CqlRequestHandler.
patch by Benoit Tellier; reviewed by Andy Tolbert, and Bret McGuire
