Summary: Optimize GridDistributedTxMapping.
Key: IGNITE-2264
URL: https://issues.apache.org/jira/browse/IGNITE-2264
Project: Ignite
Issue Type: Sub-task
Components: cache
Affects Versions: ignite-1.4
Reporter: Vladimir Ozerov
Assignee: Vladimir Ozerov
Priority: Critical
Fix For: 1.6
This class has two methods: reads() and writes(). Together they return the
whole set of entries.
The problem is that each call creates collection wrapper over entries + 1
additional iterator per each traverse over collection. This seen as a garbage
"hotspot" in flight recorder.
Actually there is no need for these methods. Instead, we can pass entries
collection directly and filter entries manually.
