-----------------------------------------
Summary: Sql. Rework execution to process batch at a time
Key: IGNITE-24923
URL: https://issues.apache.org/jira/browse/IGNITE-24923
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
Currently, execution nodes implements row-at-a-time strategy to pass rows
between operators. Although such an approach provides ultimate flexibility, it
also brings additional cost for coordination. Given that most operators
maintain internal buffer and do batch processing, we can significantly reduce
complexity of codebase by switching to batch-at-a-time strategy.
