Overview

Package dynamodbstreams provides the API client, operations, and parameter types for Amazon DynamoDB Streams.

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 (https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Streams.html) in the Amazon DynamoDB Developer Guide.

Functions

func NewDefaultEndpointResolver 

func NewDefaultEndpointResolver() *internalendpoints.Resolver

NewDefaultEndpointResolver constructs a new service endpoint resolver

func WithAPIOptions added in v1.0.0 

func WithAPIOptions(optFns ...func(*middleware.Stack) error) func(*Options)

WithAPIOptions returns a functional option for setting the Client's APIOptions option.

func WithEndpointResolver 

func WithEndpointResolver(v EndpointResolver) func(*Options)

WithEndpointResolver returns a functional option for setting the Client's EndpointResolver option.

Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client provides the API client to make operations call for Amazon DynamoDB Streams.

func New 

func New(options Options, optFns ...func(*Options)) *Client

New returns an initialized Client based on the functional options. Provide additional functional options to further configure the behavior of the client, such as changing the client's endpoint or adding custom middleware behavior.

func NewFromConfig 

func NewFromConfig(cfg aws.Config, optFns ...func(*Options)) *Client

NewFromConfig returns a new client from the provided config.

func (*Client) DescribeStream 

func (c *Client) DescribeStream(ctx context.Context, params *DescribeStreamInput, optFns ...func(*Options)) (*DescribeStreamOutput, error)

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.

func (*Client) GetRecords 

func (c *Client) GetRecords(ctx context.Context, params *GetRecordsInput, optFns ...func(*Options)) (*GetRecordsOutput, error)

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.

func (*Client) GetShardIterator 

func (c *Client) GetShardIterator(ctx context.Context, params *GetShardIteratorInput, optFns ...func(*Options)) (*GetShardIteratorOutput, error)

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.

func (*Client) ListStreams 

func (c *Client) ListStreams(ctx context.Context, params *ListStreamsInput, optFns ...func(*Options)) (*ListStreamsOutput, error)

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.

type DescribeStreamInput 

type DescribeStreamInput struct {

	// The Amazon Resource Name (ARN) for the stream.
	//
	// This member is required.
	StreamArn *string

	// The shard ID of the first item that this operation will evaluate. Use the value
	// that was returned for LastEvaluatedShardId in the previous operation.
	ExclusiveStartShardId *string

	// The maximum number of shard objects to return. The upper limit is 100.
	Limit *int32
}

Represents the input of a DescribeStream operation.

type DescribeStreamOutput 

type DescribeStreamOutput struct {

	// A complete description of the stream, including its creation date and time, the
	// DynamoDB table associated with the stream, the shard IDs within the stream, and
	// the beginning and ending sequence numbers of stream records within the shards.
	StreamDescription *types.StreamDescription

	// Metadata pertaining to the operation's result.
	ResultMetadata middleware.Metadata
}

Represents the output of a DescribeStream operation.

type EndpointResolver 

type EndpointResolver interface {

EndpointResolver interface for resolving service endpoints.

func EndpointResolverFromURL added in v1.1.0 

func EndpointResolverFromURL(url string, optFns ...func(*aws.Endpoint)) EndpointResolver

EndpointResolverFromURL returns an EndpointResolver configured using the provided endpoint url. By default, the resolved endpoint resolver uses the client region as signing region, and the endpoint source is set to EndpointSourceCustom.You can provide functional options to configure endpoint values for the resolved endpoint.

type EndpointResolverFunc 

type EndpointResolverFunc func(region string, options EndpointResolverOptions) (aws.Endpoint, error)

EndpointResolverFunc is a helper utility that wraps a function so it satisfies the EndpointResolver interface. This is useful when you want to add additional endpoint resolving logic, or stub out specific endpoints with custom values.

func (EndpointResolverFunc) ResolveEndpoint 

func (fn EndpointResolverFunc) ResolveEndpoint(region string, options EndpointResolverOptions) (endpoint aws.Endpoint, err error)

type EndpointResolverOptions added in v0.29.0 

type EndpointResolverOptions = internalendpoints.Options

EndpointResolverOptions is the service endpoint resolver options

type GetRecordsInput

	Limit *int32
}

Represents the input of a GetRecords operation.

type GetRecordsOutput 

type GetRecordsOutput struct {

	// The next position in the shard from which to start sequentially reading stream
	// records. If set to null, the shard has been closed and the requested iterator

	// The stream records from the shard, which were retrieved using the shard
	// iterator.

	// 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.
