Configurations
Variable | Detail | Required |
|---|---|---|
Name | Enter a name for the connector. | Yes |
Service account key | Service account key is a JSON or P12 file containing authentication credentials for programmatic access to Google services. You have the option to use Workload Identity Federation authorization in the service-account key file. See Configuring Workload Identity Federation Authorization to learn more. | Yes |
Project id | Project id is a unique identifier for a specific project within the Google Cloud Platform ecosystem. | Yes |
Private key | Private Key ID is a unique identifier associated with a service account's private key, used for authentication and access control in Google services. | No |
Client email | Client Email is an email address associated with a service account in a Google Cloud project, used for authentication and access to resources. | No |
Default topic | The default topic for publishing. | Yes |
Show custom attributes | If enabled, custom attributes are key-value pairs that allow you to attach additional metadata to messages in a Google Cloud Pub/Sub topic for custom processing and filtering. | No |
Parallel publish count | Parallel publish count refers to the number of concurrent message publishing operations that can be performed simultaneously using the Google Cloud Pub/Sub service, enhancing message throughput. | Yes |
Parallel byte threshold | Parallel byte threshold is the configurable limit on the size of the data payload for a batch of messages that determines when parallel publishing of messages is triggered in Google Cloud Pub/Sub for optimized data transfer. | No |
Publish count threshold | Publish count threshold is the set limit on the number of messages in a batch that triggers publishing to Google Cloud Pub/Sub, optimizing message delivery. | No |
Publish delay threshold (Milliseconds) | Publish delay threshold (Milliseconds) is the specified time interval after which accumulated messages are automatically published to Google Cloud Pub/Sub to control message delivery latency. | No |
Throttling limit | Set a limit on the number of outbound messages per second. If sending data to a server that has restrictions on the rate of incoming messages, this ensures that no messages are lost. | No |
Persistent storage | If enabled, messages in the outbound queue are stored on disk. If there are interruptions in connection or power loss, messages will be retained and eventually sent when the connection is restored. | No |
Queue mode | Select the sequence of data transfer: FIFO or LIFO. Selecting FIFO (First In First Out) will send the earliest message first. Selecting LIFO (Last In First Out) will send the latest message first. | No |
