Connections 

Starting from Lenses 5.0, all core services in Lenses are managed by Connections. It applies to:

• Kafka Brokers
• Schema Registry
• Zookeeper
• Kafka Connect
• Kerberos

Managing connections 

Connections might be managed (created, updated or deleted) without restarting Lenses, any changes are applied immediately after the connection is changed.

Connections might be managed:

• Through graphical user interface (Admin -> Connections).
• Directly via API
• With Lenses CLI provision sub-command.
• For Kubernetes - appropriate Helm configuration is used. See more about Helm installation

Some types of connections have additional limitations (for example: there might be at most 1 Kafka connection).

All information specific for a given connection type can be found in dedicated subpages, e.g. Kafka .

Testing a connection 

When creating (or editing) a connection with GUI, there is a connectivity test executed before saving the connection. It allows to check whether connection’s configuration is correct and whether Lenses is able to properly connect to third-party software.

Also there is a dedicated API endpoint to test connection configuration (see API docs for “test Kafka connection” endpoint).
