Connector classifications

Connectors are sometimes released with a Lite label or a Preview label. This topic summarizes the differences in terms of functionality between the two classifications.

• Standard connectors

  Standard connectors are fully supported by Qlik in accordance with Qlik’s Service Level Agreement (SLA) for critical issues related to data integrity, security, and reliability.

• Lite connectors

  To accelerate the availability of new SaaS application connectors, Qlik may initially develop some connectors for a specific use case and then release them with a Lite label. Lite connectors are fully supported by Qlik in accordance with Qlik’s Service Level Agreement (SLA) for critical issues related to data integrity, security, and reliability. The primary distinction is that Lite connectors are tested against a limited set of use cases, which are outlined in the documentation.

  A high-level look at the functionality available with Lite connectors, including useful links, and supported features.

  Feature/Functionality	Support details
  Supported Qlik Talend Data Integration projects	Data pipeline projects and Replication projects.
  Target update methods	Landing tasks: Change data capture (CDC) Reload and compare Replication tasks: Change data capture (CDC) using Change Tables Full load Landing data in a data lake tasks: Change data capture (CDC) Reload Information noteThe CDC update method is supported with most, but not all Lite connectors. To find out if your connector supports CDC, refer to the feature snapshot in the help for that connector.
  Managing metadata	Manual metadata generation is required.
  Schema evolution	Fully supported
  Replication of LOB columns (NCLOB, CLOB, and BLOB)	Determined by the task type: Landing tasks: Supports limited LOB size only Replication tasks: Supports unlimited LOB
  Scheduled CDC	Only required when accessing data sources without Data Movement gateway.
  Notifications	Fully supported Setting notifications for changes in operation
  Monitoring	Fully supported Monitoring an individual data task
  Automatic denesting of JSON column payloads	Fully supported

• Preview connectors

  Preview connectors are new connectors, which do not have the full functionality of Lite or Standard connectors. Like Lite and Standard connectors, they are fully supported by Qlik in accordance with Qlik’s Service Level Agreement (SLA) for critical issues related to data integrity, security, and reliability.

  A high-level look at the functionality available with Preview connectors, including useful links, and supported features.

  Feature/Capability	Support details
  Supported Qlik Talend Data Integration projects	Replication projects only. Data pipeline projects are not supported.
  Target update methods	Replication tasks: Apply changes Store changes Landing data in a data lake tasks: Change data capture (CDC)
  Managing metadata	Manual metadata generation is not required.
  Schema evolution	Only the Change column data type operation is supported.
  Replication of LOB columns (NCLOB, CLOB, and BLOB)	Not supported.
  Scheduled CDC	Required. This is how the target is kept up-to-date with changes to the source. For replication tasks, see Scheduling CDC for replication tasks For lake landing tasks, see Scheduling CDC for lake landing tasks
  Notifications	Partially supported Setting notifications for changes in operation
  Monitoring	CDC-only, as full load is not relevant for this connector. Monitoring an individual data task
  Automatic denesting of JSON column payloads	Not supported. JSON column payloads in source datasets are not denested automatically on the target.

All Qlik Talend Cloud subscriptions allow you to replicate data from Lite, Preview, and Standard connectors, with pricing based on data volume rather than connector type.

At some point in the future, a Lite or Preview connector might become a Standard connector upon validation of additional use cases (Lite connectors) or once performance has been properly validated (Preview connectors). This process ensures broader functionality and enhanced support as adoption increases.
