Vladimir Ozerov updated IGNITE-2233:
------------------------------------
Priority: Minor (was: Major)
> Avoid boxing in BinaryContext collections
> -----------------------------------------
>
> Key: IGNITE-2233
> URL: https://issues.apache.org/jira/browse/IGNITE-2233
> Project: Ignite
> Issue Type: Task
> Components: general
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Priority: Minor
> Labels: performance
> Fix For: 2.0
>
>
> 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.
