sendToGooglePubSub

Processor that acts as a Google Cloud Pub/Sub producer to publish messages to a Pub/Sub topic.

The server will use the given topic to publish messages and the given authenticationConfigKey to extract the credentials needed (such as clientId, clientEmail, privateKeyPkcs8, etc.) to establish connection to Google Cloud Pub/Sub.

Properties

Name Summary

Name	Summary
`forwardProperty()`	Adds a name to a list to convert into Pub/Sub message attributes.
`topic`	The name of the Pub/Sub topic to publish messages to. Use the simple name, not the fully qualified one.
`authenticationConfigKey`	A secret key that the server uses to look up the credentials needed to perform the authentication.
`name`	Optional, descriptive name for the processor.
`id`	Required identifier of the processor, unique across all processors within the flow. Must be between 3 and 30 characters long; contain only lower and uppercase alphabetical characters (a-z and A-Z), numbers, dashes ("-"), and underscores ("_"); and start with an alphabetical character. In other words, it adheres to the regex pattern `[a-zA-Z][a-zA-Z0-9_-]{2,29}`.
`exchangeProperties`	Optional set of custom properties in a simple jdk-format, that are added to the message exchange properties before processing the incoming payload. Any existing properties with the same name will be replaced by properties defined here.
`retainPayloadOnFailure`	Whether the incoming payload is available for error processing on failure. Defaults to `false`.

Sub-builders

Name	Summary

circuitBreakerStrategy	Strategy for configuring the processor’s circuit breaker. Optional.
messageLoggingStrategy	Strategy for describing how a processor’s message is logged on the server.
payloadArchivingStrategy	Strategy for archiving payloads.
inboundTransformationStrategy	Strategy that customizes the conversion of an incoming payload by a processor (e.g., string to object). Should be used when the processor’s default conversion logic cannot be used.
