-----------------------------------------
Summary: Sql. Update clock on query initiator node
Key: IGNITE-21552
URL: https://issues.apache.org/jira/browse/IGNITE-21552
Project: Ignite
Issue Type: Bug
Components: sql
Reporter: Konstantin Orlov
As for now, neither of sql messages update the hybrid clock. This may result in
violation of transactional protocol, since commit timestamp is calculated on
initiator node, and the clock may be behind those on nodes which processed
transactional request.
Since precise time is crucial only to calculate commit timestamp, to reduce
contention on the clock it's proposed to propagate timestamp only on
{{QueryBatchMessage}}.
See {{org.apache.ignite.internal.replicator.message.TimestampAware}} for
example of time propagation.
