What do SeekableStreamStartSequenceNumbers and SeekableStreamEndSequenceNumbers mean ?

Hi,

Could someone explain the meaning or significant of the following two
classes ?

SeekableStreamStartSequenceNumbers
SeekableStreamEndSequenceNumbers

Why do we need both of them ?

Thanks,
Dhiman

Hi,

it just means the start and end offsets in Kafka and the start and end
sequence numbers in Kinesis.
We need both to track what range of data each Kafka/Kinesis index task
processes.
