Joining and Moving Parallel Agent Work

A fan-out and a worker pool share one failure that is easy to miss, which is work that is quietly lost while every surface looks healthy. A join can complete on a partial set, and a rebalance can leave a job owned by nobody or by two workers at once. This course covers waiting for every branch before joining, treating a failed branch as a result, moving jobs between workers without losing one, and changing a shared record shape without breaking an old reader.
