创建和管理 Connector

This page describes how to create and manage connectors in HStream Platform.

Create a connector

Connector has two types: source connector and sink connector. The source connector is used to ingest data from external systems into HStream Platform, while the sink connector is used to distribute data from HStream Platform to external systems.

Create a source connector

First, navigate to the Sources page and click the New source button to go to the Create a new source page.

In this page, you should first select the Connector type. Currently, HStream Platform supports the following source connectors:

• MongoDB
• MySQL
• PostgreSQL
• SQL Server
• Generator

Click one of them to select it, and then the page will display the corresponding configuration form.

After filling in the configuration, click the Create button to create the source connector.

TIP

For more details about the configuration of each source connector, please refer to Connectors.

Create a sink connector

Create a sink connector is similar to create a source connector. First, navigate to the Sinks page and click the New sink button to go to the Create a new sink page.

Then the next steps are the same as creating a source connector.

Currently, HStream Platform supports the following sink connectors:

• MongoDB
• MySQL
• PostgreSQL
• Blackhole

View connectors

The Sources and Sinks pages display all the connectors in your account. For each connector, you can view the following information:
