Topics provide a way to organize events. After creating a cluster, you can create a topic in it. Each cluster can have up to 40,000 topics.
Topic properties are populated from information stored in the broker. Redpanda features, such as Tiered Storage, are enabled and configured by default in Redpanda Cloud. For Dedicated and BYOC clusters, you can optionally overwrite some settings.
