Kafka的topic限制是多少

How many topics can I have?

Unlike many messaging systems Kafka topics are meant to scale up arbitrarily(武断的). Hence we encourage fewer large topics rather than many small topics. So for example if we were storing notifications for users we would encourage a design with a single notifications topic partitioned by user id rather than a separate topic per user.

The actual scalability is for the most part determined by the number of total partitions across all topics not the number of topics itself.
