Overview

This page describes an overview of connecting a Lenses Agent with Schema Registries

Consider Rate Limiting if you have a high number of schemas.

Only one Schema Registry connection is allowed.

Authentication

TLS and basic authentication are supported for connections to Schema Registries.

JMX Metrics

The Agent can collect Schema registry metrics via:

1. JMX

2. Jolokia

See Infrastructure JMX Metrics.

Supported formats

• AVRO

• PROTOBUF

JSON and XML formats are supported by Lenses but without a backing schema registry.

Schema deletion

To enable the deletion of schemas in the UI, set the following in the lenses.conf file.

lenses.conf

## Enable schema deletion in the Lenses UI
## default: false
lenses.schema.registry.delete = true

## When a topic is deleted,
## automatically delete also its associated Schema Registry subjects
## default: false
lenses.schema.registry.cascade.delete = true

IBM Event Streams supports hard deletes only
