---------------------------------------
Summary: BinaryWriter is created for every a map entry
Key: IGNITE-27086
URL: https://issues.apache.org/jira/browse/IGNITE-27086
Project: Ignite
Issue Type: Improvement
Reporter: Maksim Timonin
Attachments: WritingBigMapReproducer.java
During serializing maps BinaryWriterExImpl#writeMap is called. For every key
and value it calls BinaryWriterExImpl#writeObject. Every such call creates new
BinaryWriterExImpl.
It leads to populating jvm heap with similar objects. Especially for big maps.
See example in the attach, when big map is created as argument for a
ComputeTask.
