Variables

View Source 
var Constructors = map[string]TypeSpec{}

Constructors is a map of all processor types with their specs.

View Source 
var FailFlagKey = types.FailFlagKey

FailFlagKey is a metadata key used for flagging processor errors in Benthos. If a message part has any non-empty value for this metadata key then it will be interpretted as having failed a processor step somewhere in the pipeline.

Functions

func Block 

func Block(typeStr, reason string)

Block replaces the constructor of a Benthos processor such that its construction will always return an error. This is useful for building strict pipelines where certain processors should not be available. NOTE: This does not remove the processor from the configuration spec, and normalisation will still work the same for blocked processors.

EXPERIMENTAL: This function is experimental and therefore subject to change outside of major version releases.

func ClearFail 

func ClearFail(part types.Part)

ClearFail removes any existing failure flags from a message part.

func Descriptions 

func Descriptions() string

Descriptions returns a formatted string of collated descriptions of each type.

func DocumentPlugin 

func DocumentPlugin(
	typeString, description string,
	configSanitiser PluginConfigSanitiser,
)

DocumentPlugin adds a description and an optional configuration sanitiser function to the definition of a registered plugin. This improves the documentation generated by PluginDescriptions.

func ExecuteAll 

func ExecuteAll(procs []types.Processor, msgs ...types.Message) ([]types.Message, types.Response)

ExecuteAll attempts to execute a slice of processors to a message. Returns N resulting messages or a response. The response may indicate either a NoAck in the event of the message being buffered or an unrecoverable error.

func ExecuteCatchAll 

func ExecuteCatchAll(procs []types.Processor, msgs ...types.Message) ([]types.Message, types.Response)

ExecuteCatchAll attempts to execute a slice of processors to only messages that have failed a processing step. Returns N resulting messages or a response. The response may indicate either a NoAck in the event of the message being buffered or an unrecoverable error.

func ExecuteTryAll 

func ExecuteTryAll(procs []types.Processor, msgs ...types.Message) ([]types.Message, types.Response)

ExecuteTryAll attempts to execute a slice of processors to messages, if a message has failed a processing step it is prevented from being sent to subsequent processors. Returns N resulting messages or a response. The response may indicate either a NoAck in the event of the message being buffered or an unrecoverable error.

func FlagErr 

func FlagErr(part types.Part, err error)

FlagErr marks a message part as having failed at a processing step with an error message. If the error is nil the message part remains unchanged.

func FlagFail 

func FlagFail(part types.Part)

FlagFail marks a message part as having failed at a processing step.

func HasFailed 

func HasFailed(part types.Part) bool

HasFailed checks whether a message part has failed a processing step.

func IteratePartsWithSpan 

func IteratePartsWithSpan(
	operationName string, parts []int, msg types.Message,
	iter func(int, opentracing.Span, types.Part) error,
)

IteratePartsWithSpan iterates the parts of a message according to a slice of indexes (if empty all parts are iterated) and calls a func for each part along with a tracing span for that part. If an error is returned the part is flagged as failed and the span has the error logged.

func PluginCount 

func PluginCount() int

PluginCount returns the number of registered plugins. This does NOT count the standard set of components.

func PluginDescriptions 

func PluginDescriptions() string

PluginDescriptions generates and returns a markdown formatted document listing each registered plugin and an example configuration for it.

func RegisterPlugin 

func RegisterPlugin(
	typeString string,
	configConstructor PluginConfigConstructor,
	constructor PluginConstructor,
)

RegisterPlugin registers a plugin by a unique name so that it can be constructed similar to regular processors. If configuration is not needed for this plugin then configConstructor can be nil. A constructor for the plugin itself must be provided.

func SanitiseConfig 

func SanitiseConfig(conf Config) (interface{}, error)

SanitiseConfig returns a sanitised version of the Config, meaning sections that aren't relevant to behaviour are removed.

Eventually, when the batch reaches its target size, the batch is sent through the pipeline as a single message and an acknowledgement for that message determines whether the whole batch of messages are acknowledged.
