Managing Connectors and Connector Servers
Composer connects to a wide array of data sources available in the marketplace today—from modern databases (including Hadoop, Search, Streaming, and NoSQL) to traditional sources like SQL-based stores. Composer comes prepackaged with connectors that are automatically installed during the Composer installation process.
JDBC drivers for a few of the connectors are no longer included in the installation package. This means that if you use one of these connectors, you also need to configure a JDBC driver before it can be enabled and accessible from Composer. For additional details, including the list of connectors, see Adding a JDBC Driver.
If the connector you are looking for is not shown, it may be because:
- The connector is installed but is not enabled. For more information, see Enabling and Disabling Connectors.
- The connector was not installed and needs to be downloaded separately. For more information, see Obtaining Additional Connector Servers.
- The connector requires you to provide a licensed JDBC driver. For more information, see Adding a JDBC Driver.
See Composer v5 Data Connector Reference for the full list of supported Composer connectors.
Management of connector microservices is split into two sections:
- Connector Servers
Each connector server runs independently in the Composer environment. You can set up a connection type for each connector server and manage the ones to be available to users in the Composer account.
This means that you are able to enable or disable any of these servers at any time, depending on the data stores that you use and need to use with Composer. The following figure provides a high level concept diagram of the Composer environment.
The setup and management of connector servers in the Composer environment is handled on the Manage Connector Services page, which is accessible to supervisors. To make the actual connection between Composer and your data source after the connector server has been configured, log into Composer as an administrator and access the Sources page, accessible from the UI menu. See Connect Composer v5 to Data Stores.
The Manage Connector Services page (available to supervisors) lets you register or remove connector servers that are not available out-of-the-box in the Composer instance. You can also use this page to maintain, enable, and disable connector definitions based on the connector servers defined in the Composer instance. See Manage Connector Services Page.
The Connections page (available to administrators and users with appropriate privileges) lets you define the connection for a connector between Composer and a data store. See Connect Composer v5 to Data Stores.
