-------------------------------------------
Summary: Avoid constant boxing in ColumnStats.{Min/Max}Tracker
Key: CASSANDRA-8109
URL: https://issues.apache.org/jira/browse/CASSANDRA-8109
Project: Cassandra
Issue Type: Improvement
Reporter: Sylvain Lebresne
Priority: Minor
Fix For: 3.0
We use the {{ColumnStats.MinTracker}} and {{ColumnStats.MaxTracker}} to track
timestamps and deletion times in sstable. Those classes are generics but we
really ever use them for longs and integers. The consequence is that every call
to their {{update}} method (called for every cell during sstable write) box
it's argument (since we don't store the cell timestamps and deletion time
boxed). That feels like a waste that is easy to fix: we could just make those
work on longs only for instance and convert back to int at the end when that's
what we need.
