----------------------------------
Labels: EventNotification pull-request-available (was: EventNotification)
> Replace In-Memory Event Checkpointing with Durable Persistence Strategy
> -----------------------------------------------------------------------
>
> Key: HDDS-15562
> URL: https://issues.apache.org/jira/browse/HDDS-15562
> Project: Apache Ozone
> Issue Type: New Feature
> Reporter: Donal Magennis
> Priority: Major
> Labels: EventNotification, pull-request-available
>
> The initial in-memory checkpoint strategy for the ledger consumer does not
> persist seek positions across Ozone Manager restarts.
> To support reliable "at-least-once" delivery of event notifications, the
> ledger poller requires a persistent checkpointing strategy which is
> distributed across OMs.
> We can do this by using the Ozone filesystem itself to persist the latest
> checkpoint.
