Adrian Cole created CASSANDRA-16304:
---------------------------------------
Summary: Consider implementing ClusteringComparator without a
lambda
Key: CASSANDRA-16304
URL: https://issues.apache.org/jira/browse/CASSANDRA-16304
Project: Cassandra
Issue Type: Improvement
Reporter: Adrian Cole
Using lambdas forces jamm to do things that can easily break. It might be safer
to implement things like ClusteringComparator directly as classes or as an enum
