One of the property is auto.create.topics.enable if you set this to true (by default) kafka will automatically create a topic when you send a message to a non existing topic. But I want to create a topic through java api. Customers should use a user-assigned managed identity with the Azure Key Vault (AKV) to achieve this. Existing connector implementations are normally available for common data sources and sinks with the option of creating ones own connector. For a topic with replication factor N, Kafka can tolerate up to N-1 server failures without losing any messages committed to the log.
