-------------------------------------
Summary: Seed the cache from offset persisted in the source
repository
Key: SLING-9482
URL: https://issues.apache.org/jira/browse/SLING-9482
Project: Sling
Issue Type: Bug
Components: Content Distribution
Reporter: Timothee Maret
Assignee: Timothee Maret
The approach taken in SLING-9460 to avoid sending seeding messages does not
address some scenarios like publishing content without subscriber agents.
Without subscriber agents.
To be sure we always have a recent seed available, we should persist seed
offsets in the source repository (typ. author) and seed caches from it. We do
have the local store class that allows to easily write the offsets in the
repository. To not stress the repository too much, we should batch those writes
(e.g. 1 offset update every 10 package processed). To support a cluster, the
writes must be initiated only from the cluster leader instance.
