[jira] [Created] (IGNITE-4554) Optimize integer sets and arrays.
Alexei Scherbakov created IGNITE-4554:
-----------------------------------------
Summary: Optimize integer sets and arrays.
Key: IGNITE-4554
URL: https://issues.apache.org/jira/browse/IGNITE-4554
Project: Ignite
Issue Type: Improvement
Components: general
Affects Versions: 1.6
Reporter: Alexei Scherbakov
Assignee: Alexei Scherbakov
Fix For: 2.1
Ignite has many uses of data structures like Set<Integer>, IntArray etc.
This is not most efficient way to represent integer sets. The best way is to use compressed bit sets. This should save a lot of heap space.
We should optimize integer sets whenever possible.
The most obvious place to start is GridAffinityAssignment.
