class Aws::DynamoDBStreams::Types::GetShardIteratorInput

Represents the input of a `GetShardIterator` operation.

@note When making an API call, you may pass GetShardIteratorInput

data as a hash:

    {
      stream_arn: "StreamArn", # required
      shard_id: "ShardId", # required
      shard_iterator_type: "TRIM_HORIZON", # required, accepts TRIM_HORIZON, LATEST, AT_SEQUENCE_NUMBER, AFTER_SEQUENCE_NUMBER
      sequence_number: "SequenceNumber",
    }

@!attribute [rw] stream_arn

The Amazon Resource Name (ARN) for the stream.
@return [String]

@!attribute [rw] shard_id

The identifier of the shard. The iterator will be returned for this
shard ID.
@return [String]

@!attribute [rw] shard_iterator_type

Determines how the shard iterator is used to start reading stream
records from the shard:

* `AT_SEQUENCE_NUMBER` - Start reading exactly from the position
  denoted by a specific sequence number.

* `AFTER_SEQUENCE_NUMBER` - Start reading right after the position
  denoted by a specific sequence number.

* `TRIM_HORIZON` - Start reading at the last (untrimmed) stream
  record, which is the oldest record in the shard. In DynamoDB
  Streams, there is a 24 hour limit on data retention. Stream
  records whose age exceeds this limit are subject to removal
  (trimming) from the stream.

* `LATEST` - Start reading just after the most recent stream record
  in the shard, so that you always read the most recent data in the
  shard.
@return [String]

@!attribute [rw] sequence_number

The sequence number of a stream record in the shard from which to
start reading.
@return [String]
