---------------------------------------
Summary: Avoid boxing in BinaryContext collections
Key: IGNITE-2233
URL: https://issues.apache.org/jira/browse/IGNITE-2233
Project: Ignite
Issue Type: Sub-task
Components: general
Affects Versions: ignite-1.4
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
Fix For: 1.6
The following methods generate visible GC pressure due to constant boxing of
int keys:
BinaryContext.descriptorForTypeId
BinaryContext.userTypeIdMapper
BinaryContext.schemaRegistry
Possilbe solutions:
1) int -> Object maps (e.g. see Martin Thompson's Argona lib).
2) COW semantics instead of concurrent maps/sets as these collections are
updated only during warmup.
