-------------------------------------
Summary: 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
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.
