------------------------------------------
Summary: getFunctions methods produce too much garbage
Key: CASSANDRA-11593
URL: https://issues.apache.org/jira/browse/CASSANDRA-11593
Project: Cassandra
Issue Type: Improvement
Reporter: Benjamin Lerer
Assignee: Benjamin Lerer
Fix For: 3.x
While profiling an heavy write workload on a single machine, I discover that
calls to {{getFunctions}} were producing a lot of garbage.
Internally, the getFunctions method use {{Iterators}} or {{Iterables}}
functions that creates new immutable collections at each level.
As {{getFunctions}} is called for each SELECT, INSERT, UPDATE or DELETE through
the {{checkAccess}} method the impact is not neglectable.
