-----------------------------------------
Summary: Sql. Improve intra-query parallelism
Key: IGNITE-21809
URL: https://issues.apache.org/jira/browse/IGNITE-21809
Project: Ignite
Issue Type: Improvement
Components: sql
Reporter: Konstantin Orlov
At the moment, intra-query parallelism is achieved by splitting the query on
several fragments in the place where distribution conversion is required, but
the fragment itself is tied up to a single thread. Such a parallelization
results in a low resource utilization by a single query, especially in case of
huge fragments like the ones containing aggregation or colocated joins.
