Overview

The Airbyte Google PubSub destination allows you to send/stream data into PubSub. Pub/Sub is an asynchronous messaging service provided by Google Cloud Provider.

Prerequisites

• For Airbyte Open Source users using the Postgres source connector, upgrade your Airbyte platform to version v0.40.0-alpha or newer and upgrade your PubSub connector to version 0.1.6 or newer

Sync overview

Output schema

Each stream will be output a PubSubMessage with attributes. The message attributes will be

• _stream: the name of stream where the data is coming from
• _namespace: namespace if available from the stream

The data will be a serialized JSON, containing the following fields

• _airbyte_ab_id: a uuid string assigned by Airbyte to each event that is processed.
• _airbyte_emitted_at: a long timestamp(ms) representing when the event was pulled from the data source.
• _airbyte_data: a json string representing source data.

Getting started

Requirements

To use the PubSub destination, you'll need:

• A Google Cloud Project with PubSub enabled
• A PubSub Topic to which Airbyte can stream/sync your data
• A Google Cloud Service Account with the Pub/Sub Editor role in your GCP project
• A Service Account Key to authenticate into your Service Account

See the setup guide for more information about how to create the required resources.

Setup guide

Google cloud project

If you have a Google Cloud Project with PubSub enabled, skip to the "Create a Topic" section.

First, follow along the Google Cloud instructions to Create a Project. PubSub is enabled automatically in new projects. If this is not the case for your project, find it in Marketplace and enable.

PubSub topic for Airbyte syncs

Airbyte needs a topic in PubSub to write the data being streamed/synced from your data sources. If you already have a Topic into which Airbyte should stream/sync data, skip this section. Otherwise, follow the Google Cloud guide for Creating a PubSub Topic to achieve this.

Service account

In order for Airbyte to stream/sync data into PubSub, it needs credentials for a Service Account with the Pub/Sub Editor role, which grants permissions to publish messages into PubSub topics. We highly recommend that this Service Account is exclusive to Airbyte for ease of permissioning and auditing. However, you can use a pre-existing Service Account if you already have one with the correct permissions.

The easiest way to create a Service Account is to follow GCP's guide for Creating a Service Account. Once you've created the Service Account, make sure to keep its ID handy as you will need to reference it when granting roles. Service Account IDs typically take the form <account-name>@<project-name>.iam.gserviceaccount.com

Then, add the service account as a Member in your Google Cloud Project with the Pub/Sub Editor role. To do this, follow the instructions for Granting Access in the Google documentation. The email address of the member you are adding is the same as the Service Account ID you just created.

At this point you should have a service account with the Pub/Sub Editor project-level permission.

Service account key

Service Account Keys are used to authenticate as Google Service Accounts. For Airbyte to leverage the permissions you granted to the Service Account in the previous step, you'll need to provide its Service Account Keys. See the Google documentation for more information about Keys.

Follow the Creating and Managing Service Account Keys guide to create a key. Airbyte currently supports JSON Keys only, so make sure you create your key in that format. As soon as you created the key, make sure to download it, as that is the only time Google will allow you to see its contents. Once you've successfully configured BigQuery as a destination in Airbyte, delete this key from your computer.

Setup the PubSub destination in Airbyte

You should now have all the requirements needed to configure PubSub as a destination in the UI. You'll need the following information to configure the PubSub destination:

• Project ID: GCP project id
• Topic ID: name of pubsub topic under the project
• Service Account Key: the contents of your Service Account Key JSON file

Once you've configured PubSub as a destination, delete the Service Account Key from your computer.
