---------------------------------------

             Summary: SQL: Batch DML updates on per-node basis
                 Key: IGNITE-6080
                 URL: https://issues.apache.org/jira/browse/IGNITE-6080
             Project: Ignite
          Issue Type: Task
    Affects Versions: 2.1
            Reporter: Vladimir Ozerov
            Assignee: Vladimir Ozerov
             Fix For: 2.2


Currently DML updates are batched and then applied using {{IgniteCache.invokeAll}}. See {{org.apache.ignite.internal.processors.query.h2.DmlStatementsProcessor#processPage}}.
This is not efficient, because typical update will hit a lot of data nodes.

Instead, we should create separate batches for every primary node. This way we can significantly
improve update performance.
