Amazon DynamoDB

Amazon DynamoDB Streams provides API actions for accessing streams and processing stream records. To learn more about application development with Streams, see Capturing Table Activity with DynamoDB Streams in the Amazon DynamoDB Developer Guide.

Link to this section Summary

Functions

Returns a map containing the input/output shapes for this endpoint

Outputs values common to all actions

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

Retrieves the stream records from a given shard

Returns a shard iterator. A shard iterator provides information about how to retrieve the stream records from within a shard. Use the shard iterator in a subsequent GetRecords request to read the stream records from the shard

Returns an array of stream ARNs associated with the current account and endpoint. If the TableName parameter is present, then ListStreams will return only the streams ARNs for that table

Link to this function describe_stream(input \\ %{}, options \\ [])

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.

Link to this function get_records(input \\ %{}, options \\ [])

Retrieves the stream records from a given shard.

Specify a shard iterator using the ShardIterator parameter. The shard iterator specifies the position in the shard from which you want to start reading stream records sequentially. If there are no stream records available in the portion of the shard that the iterator points to, GetRecords returns an empty list. Note that it might take multiple calls to get to a portion of the shard that contains stream records.

`GetRecords` can retrieve a maximum of 1 MB of data or 1000 stream records, whichever comes first.
Link to this function get_shard_iterator(input \\ %{}, options \\ [])

Returns a shard iterator. A shard iterator provides information about how to retrieve the stream records from within a shard. Use the shard iterator in a subsequent GetRecords request to read the stream records from the shard.

A shard iterator expires 15 minutes after it is returned to the requester.
Link to this function list_streams(input \\ %{}, options \\ [])

Returns an array of stream ARNs associated with the current account and endpoint. If the TableName parameter is present, then ListStreams will return only the streams ARNs for that table.

You can call `ListStreams` at a maximum rate of 5 times per second.
