Struct rusoto_dynamodbstreams::GetShardIteratorInput

pub struct GetShardIteratorInput {
    pub sequence_number: Option<String>,
    pub shard_id: String,
    pub shard_iterator_type: String,
    pub stream_arn: String,
}

Represents the input of a GetShardIterator operation.

Fields

sequence_number: Option<String>

The sequence number of a stream record in the shard from which to start reading.

shard_id: String

The identifier of the shard. The iterator will be returned for this shard ID.

shard_iterator_type: String

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

• ATSEQUENCENUMBER - Start reading exactly from the position denoted by a specific sequence number.

• AFTERSEQUENCENUMBER - 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.

stream_arn: String

The Amazon Resource Name (ARN) for the stream.
