Internal caches should be replicated across sites

    XMLWordPrintable

Details

    Description

      Given a cache manager, we should look for all enabled x-site locations and add those sites as SYNC backups for the protobuf metadata cache. Without this data, the user has to implement its own code to make sure the data is added in each site which is troublesome.

      Using SYNC/FAIL combo turns out to be very buggy. In the initial test created, only one site was up and the other was not. The put call to replicate the metadata was failing (as a result of ISPN-9113) but this was going under the radar (more tests needed!), and it ended up waiting for the replication timeout to happen.

      Even after replication timeout happened, the put call was completing fine. This is because invocation batching was enabled for protobuf metadata cache which means any update failures would not make the cache operations fail.

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
