> In order to minimize dependency on Sling Jobs and improve performance we should offer an implementation passive queues in JCR.
> Passive queues are distribution queues [1] for which no queue processor is defined. They are only used to store items and do not need rebalancing between instances. They just need to be stored and fetched (FIFO semantics) and this can easily be implemented in JCR with a simpler implementation that does not use querying (querying for jobs is problematic like OAK-7495 shows).
