---------------------------------------
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.
