             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
