Hi, I can run a producer to send data to a particular partition within a topic by specifying the topic ID and the partition ID, then a consumer can receive a particular partition within a topic by subscribing with the topic ID and partition ID.
If I have n consumers, each subscribes to a topic/partition exclusively, can I either create n topics with one partition or create one topic with n partitions? If it can, in both situations, the server will open n log directories, Both situations require the same open file handlers, both increase the end to end latency, so which is the better practice to use large number of topics each has one partition, or to use a single topic with large number of partitions in terms of resource consumption, efficiency and scalability in a broker? Thanks. - j
