NAME

Paws::DynamoDBStreams - Perl Interface to AWS Amazon DynamoDB Streams

SYNOPSIS

  use Paws;

  my $obj = Paws->service('DynamoDBStreams');
  my $res = $obj->Method(
    Arg1 => $val1,
    Arg2 => [ 'V1', 'V2' ],
    # if Arg3 is an object, the HashRef will be used as arguments to the constructor
    # of the arguments type
    Arg3 => { Att1 => 'Val1' },
    # if Arg4 is an array of objects, the HashRefs will be passed as arguments to
    # the constructor of the arguments type
    Arg4 => [ { Att1 => 'Val1'  }, { Att1 => 'Val2' } ],
  );

DESCRIPTION

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.

METHODS

DescribeStream(StreamArn => Str, [ExclusiveStartShardId => Str, Limit => Int])

Each argument is described in detail in: Paws::DynamoDBStreams::DescribeStream

Returns: a Paws::DynamoDBStreams::DescribeStreamOutput instance

  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.

GetRecords(ShardIterator => Str, [Limit => Int])

Each argument is described in detail in: Paws::DynamoDBStreams::GetRecords

Returns: a Paws::DynamoDBStreams::GetRecordsOutput instance

  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.

GetShardIterator(ShardId => Str, ShardIteratorType => Str, StreamArn => Str, [SequenceNumber => Str])

Each argument is described in detail in: Paws::DynamoDBStreams::GetShardIterator

Returns: a Paws::DynamoDBStreams::GetShardIteratorOutput instance

  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 C<GetRecords> request to read the stream
records from the shard.

A shard iterator expires 15 minutes after it is returned to the requester.

ListStreams([ExclusiveStartStreamArn => Str, Limit => Int, TableName => Str])

Each argument is described in detail in: Paws::DynamoDBStreams::ListStreams

Returns: a Paws::DynamoDBStreams::ListStreamsOutput instance

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

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

PAGINATORS

Paginator methods are helpers that repetively call methods that return partial results
