Tzu-Li (Gordon) Tai updated FLINK-6653:
---------------------------------------
Description:
Currently, the Kinesis consumer's checkpoints directly serialize AWS's
{{Shard}} instances in checkpoints. This makes bumping AWS library versions
hard, since any change to the {{Shard}} class by AWS will break checkpoint
compatibility.
We should either have custom serialization for {{KinesisStreamShard}}, or
disintegrate the information in {{Shard}}. Ideally, it would be best to make
{{KinesisStreamShard}} and {{SequenceNumber}} to be non-serializable, hence
avoiding Java serialization in the checkpoints.
