feyman commented on KAFKA-10097: -------------------------------- Cool, thanks a lot! [~bchen225242] > Avoid getting null map for task checkpoint > ------------------------------------------ > > Key: KAFKA-10097 > URL: https://issues.apache.org/jira/browse/KAFKA-10097 > Project: Kafka > Issue Type: Improvement > Components: streams > Reporter: Boyang Chen > Priority: Major > > In StreamTask, we have the logic to generate a checkpoint offset map to be > materialized through StateManager#checkpoint. This map could be either empty > map or null, which the former case indicates to only pull down existing state > store checkpoint data, while the latter indicates no need to do a checkpoint > in the case such as we are suspending a task. > Having two similar special logics for checkpointing could lead to unexpected > bugs, also we should think about separating the empty checkpoint case vs > passed-in checkpoint case. -- This message was sent by Atlassian Jira (v8.3.4#803005)
