GitHub user nareshv edited a discussion: Whats the right sizing of producers & consumers on a partitioned topic with all subscription types ?
Other messaging systems that support competing consumer pattern allows multiple consumers on a queue with same subscription name. Kafka supports one consumer group to have multiple consumers that have 1:1 mapping with the partitions in a topic With Pulsar, due to multiple types of consumption, it isnt' very clear on right sizing the (#producers , topic, #partitions, subscription, subscriptionType, #consumers) to ensure that there is steady state. ``` | Producers/Partition | Partitions in Topic | Subscription | Subscription Type | Consumer Instances | |---------------------|---------------------|--------------|-------------------|--------------------| | 1 | 10 | 1 | Exclusive | ?? | | 1 | 10 | 1 | Failover | ?? | | 1 | 10 | 1 | Shared | ?? | | 1 | 10 | 1 | Key_Shared | ?? | ``` GitHub link: https://github.com/apache/pulsar/discussions/22437 ---- This is an automatically sent email for [email protected].
