Chris Riccomini commented on SAMZA-329:
---------------------------------------
Not sure how this ticket would be affected by a ConfigLog (as discussed in
SAMZA-123). If we end up using the ConfigLog as a way to send signals to
containers, then the containers will still need to read the log. That said,
having the AM read the config log and pass in static stuff to the containers at
start time doesn't prohibit the containers from also reading the log, thought
it might not provide any gain.
> AM should read checkpoints and provide them to containers

> Currently each container reads its checkpoint partition to find the latest
> offsets. Post SAMZA-123, the checkpoints are written into a single-partition
> topic that each container reads through, discarding those checkpoints for
> which it does not have SSPs. It would be better if the AM were to read the
> checkpoint once and pass the offset to the container as part of the input
> stream definition.
