Returns information about a stream, including the current status of the
stream, its Amazon Resource Name (ARN), the composition of its shards,
and its corresponding DynamoDB table.
You can call DescribeStream
at a maximum rate of 10 times per second.
Each shard in the stream has a SequenceNumberRange
associated with it.
If the SequenceNumberRange
has a StartingSequenceNumber
but no
EndingSequenceNumber
, then the shard is still open (able to receive
more stream records). If both StartingSequenceNumber
and
EndingSequenceNumber
are present, then that shard is closed and can no
longer receive more data.
