----------------------------------------
Summary: Improved Priority queue
Key: ARTEMIS-1383
URL: https://issues.apache.org/jira/browse/ARTEMIS-1383
Project: ActiveMQ Artemis
Issue Type: Improvement
Components: Broker
Reporter: Francesco Nigro
Assignee: Francesco Nigro
The original PriorityLinkedList implementation is based on a double linked list
implementation that suffer of:
* fragmentation along the heap
* pointer chasing due to the presence of nodes
* allocation heavy (ie each add operation forces allocation of nodes)
* high hidden (ie the nodes) memory footprint that lead to wrong memory
estimations
It is possible to provide a specialized chunked implementation that can address
all these issues while providing a better performance (throughput, latency and
memory footprint wise).
