Summary: Calcite engine. Optimize mapping sending with query start
request
Key: IGNITE-19981
URL: https://issues.apache.org/jira/browse/IGNITE-19981
Project: Ignite
Issue Type: Improvement
Reporter: Aleksey Plekhanov
Assignee: Aleksey Plekhanov
Currently we send the whole fragment mapping with query start request to each
node, but on the node we need only local mapping (we need only set of partition
to process by current node). If there are a lot of nodes and a lot of
partitions - mapping can take a lot of space
