Google PubSub Connector Overview¶
The Google Pub/Sub connector allows you to access the Google Cloud Pub/Sub API Version v1 through WSO2 EI. Google Cloud Pub/Sub is a fully-managed real-time messaging service that allows you to send and receive messages between independent applications.
The Google Pub/Sub Connector allows developers to make asynchronous messaging flows inside WSO2 EI mediation. It facilitates to achieve the following use-cases.
- One-to-many messaging. WSO2 EI can place a message in a topic and many other parties can consume it.
- Distributing event notifications - WSO2 EI can send events to Google Pub Sub and interested event listeners will get triggered.
- Streaming sensor data to Google cloud using WSO2 EI
- Reliability improvement in processing messages. Messages received by WSO2 EI can be sent to Google Pub Sub and later received and processed by an WSO2 EI in a different region.
