----------------------------------------
Summary: ArrivalWindow should use primitives
Key: CASSANDRA-9496
URL: https://issues.apache.org/jira/browse/CASSANDRA-9496
Project: Cassandra
Issue Type: Improvement
Reporter: sankalp kohli
Priority: Minor
While doing a heap analysis of a large cluster(1000+), I found that majority of
the strongly referenced objects on heap are coming from ArrivalWindow.
Currently ArrivalWindow uses BoundedStatsDeque which uses
LinkedBlockingDeque<Long> deque.
For a cluster of size 1000, it will translate into 2 million objects.
We can use primitives and use an array of long(long[]). This will cut down on
the number of objects and the change is not that big.
