Summary: Ability to disable WAL (Recoverable case) Key: IGNITE-7005 URL: https://issues.apache.org/jira/browse/IGNITE-7005 Project: Ignite Issue Type: Sub-task Reporter: Anton Vinogradov Assignee: Anton Vinogradov In addition to non recoverable case: On WAL disabling we should (on each node) - trigger exchange to guarantie consistent state - schedule new checkpoint. This checkpoint should be recorded to special place (temporary checkpoint location), to prevent damage of latest one. All new checkpoints should update temporary checkpoint. On WAL enabling we should (on each node) after all nodes reported that checkpoints finished - merge temp checkpoint with stable (scheduled before WAL disabling) - clean WAL before enabling proxies On any failure during loading (while WAL disabled or enabling) we should be able to reactivate cluster with - data from original checkpoints & WAL for affected caches - latest state for non affected caches Failover: Any topology change should be covered(while WAL disabled or enabling) - Node(s) Left (inc. coordinator) - Node(s) Join -- This message was sent by Atlassian JIRA (v6.4.14#64029)
