FAQs

When I enter the topic, I can’t view the data

There are a couple of reasons as why this might be happening:

• User has no permission to view the data.
• Selected Topic partition might be empty. Make sure to choose a partition with data.
• Lenses cannot desirialize the records of the topic. This means that either:
  1. The topic has Avro data and Schema Registry is down.
  2. The data you’re trying to read is not compatible with the Topics Schema.

In those cases the records are treated as bad records and are being skipped. You can debug this through the SQL studio
