	// contains filtered or unexported fields
}

AmazonS3 is a benthos writer.Type implementation that writes messages to an Amazon S3 bucket.

func NewAmazonS3 added in v0.7.5

func NewAmazonS3(
	conf AmazonS3Config,
	log log.Modular,
	stats metrics.Type,
) *AmazonS3

NewAmazonS3 creates a new Amazon S3 bucket writer.Type.

func (*AmazonS3) CloseAsync added in v0.7.5

func (a *AmazonS3) CloseAsync()

CloseAsync begins cleaning up resources used by this reader asynchronously.

func (*AmazonS3) Connect added in v0.7.5

func (a *AmazonS3) Connect() error

Connect attempts to establish a connection to the target S3 bucket and any relevant queues used to traverse the objects (SQS, etc).

func (*AmazonS3) WaitForClose added in v0.7.5

func (a *AmazonS3) WaitForClose(time.Duration) error

WaitForClose will block until either the reader is closed or a specified timeout occurs.

func (*AmazonS3) Write added in v0.7.5

func (a *AmazonS3) Write(msg types.Message) error

Write attempts to write message contents to a target S3 bucket as files.

type AmazonS3Config added in v0.7.5

type AmazonS3Config struct {
	Region      string                     `json:"region" yaml:"region"`
	Bucket      string                     `json:"bucket" yaml:"bucket"`
	Path        string                     `json:"path" yaml:"path"`
	Credentials AmazonAWSCredentialsConfig `json:"credentials" yaml:"credentials"`
	TimeoutS    int64                      `json:"timeout_s" yaml:"timeout_s"`
}

func (*Kafka) CloseAsync

func (k *Kafka) CloseAsync()

CloseAsync shuts down the Kafka writer and stops processing messages.

func (*Kafka) Connect

func (k *Kafka) Connect() error

Connect attempts to establish a connection to a Kafka broker.

func (*Kafka) WaitForClose

func (k *Kafka) WaitForClose(timeout time.Duration) error

WaitForClose blocks until the Kafka writer has closed down.

func (*Kafka) Write

func (k *Kafka) Write(msg types.Message) error

Write will attempt to write a message to Kafka, wait for acknowledgement, and returns an error if applicable.

type KafkaConfig

type KafkaConfig struct {
	Addresses   []string `json:"addresses" yaml:"addresses"`
	ClientID    string   `json:"client_id" yaml:"client_id"`
	Topic       string   `json:"topic" yaml:"topic"`

	// contains filtered or unexported fields
}

RedisList is an output type that serves RedisList messages.

func NewRedisList

func NewRedisList(
	conf RedisListConfig,
	log log.Modular,
	stats metrics.Type,
) (*RedisList, error)

NewRedisList creates a new RedisList output type.

func (*RedisList) CloseAsync

func (r *RedisList) CloseAsync()

CloseAsync shuts down the RedisList output and stops processing messages.

func (*RedisList) Connect

func (r *RedisList) Connect() error

Connect establishes a connection to an RedisList server.

func (*RedisList) WaitForClose

func (r *RedisList) WaitForClose(timeout time.Duration) error

WaitForClose blocks until the RedisList output has closed down.

func (*RedisList) Write

func (r *RedisList) Write(msg types.Message) error

Write attempts to write a message by pushing it to the end of a Redis list.

type RedisListConfig

type RedisListConfig struct {
	URL string `json:"url" yaml:"url"`
	Key string `json:"key" yaml:"key"`
}

RedisListConfig is configuration for the RedisList output type.

func NewRedisListConfig

func NewRedisListConfig() RedisListConfig

NewRedisListConfig creates a new RedisListConfig with default values.

type Type

type Type interface {
	// Connect attempts to establish a connection to the sink, if unsuccessful
	// returns an error. If the attempt is successful (or not necessary) returns
	// nil.
	Connect() error

	// Write should block until either the message is sent (and acknowledged) to
	// a sink, or a transport specific error has occurred, or the Type is
