Struct rusoto_dynamodbstreams::GetShardIteratorInput [−][src]
pub struct GetShardIteratorInput { pub sequence_number: Option<String>, pub shard_id: String, pub shard_iterator_type: String, pub stream_arn: String, }
Expand description
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.
