-----------------------------------------
Summary: Topology version must be extended with topology epoch
Key: IGNITE-17880
URL: https://issues.apache.org/jira/browse/IGNITE-17880
Project: Ignite
Issue Type: Sub-task
Reporter: Anton Vinogradov
Epoch must be incremented each time when topology version changed from 0 to 1
(when the cluster started or restarted).
Each epoch decrease or invariance on join must be logged as a warning.
Epoch must be logged at every topology version change.
This will
- help to determine how many times the cluster was restarted (and make it
easier to determine when)
- checks that the part of the cluster which was restarted sometimes as a
standalone cluster will never join the rest of the cluster with the lower epoch
(check some segmentation and management problems)
