-----------------------------------------
Summary: Sql. Investigate disabling back pressure on Exchange
Key: IGNITE-21686
URL: https://issues.apache.org/jira/browse/IGNITE-21686
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
In IGNITE-21668 order-preserving exchange was disabled for multinode target.
Alternative solution to the deadlock is to disable backpressure for such
exchange. In that case we can potentially save time on re-sorting, while
occupied memory will be the same.
We need to figure out if there are downsides to disabling backpressure.
