Summary: Optimize memory usage of AbstractEventProducer#fireEvent
Key: IGNITE-21198
URL: https://issues.apache.org/jira/browse/IGNITE-21198
Project: Ignite
Issue Type: Improvement
Reporter: Ivan Bessonov
Assignee: Ivan Bessonov
In current implementation, most of listeners do their work synchronously and
return already completed futures. In that cases there's no sense to allocate
the entire array of futures and fill it.
Another reason for not allocating an array right away is the fact that we may
have a big number of listeners, and allocating an array will be expensive and
wasteful.
