> As a part of SAMZA-465, the checkpoints are now a part of coordinator stream. This migration needs to be seamless to migrate the checkpoint from the checkpoint topic to coordinator stream when upgrade from 0.9.0 happens, this ticket will focus on doing this (for e.g., from the Job coordinator, we read and write to coordinator stream before we start the containers).
