@sijie the default behavior of stored data in pulsar is not exactly the same as data in a file. By default data is not persisted in Pulsar at all. Only if a topic has a subscription or retention configured is the data actually persisted. Thus, if you want to Readers to able to read a certain amount of data, the user should configure the appropriate retention. I would recommend that is the correct workflow we should recommend users that want to use Readers. I would also argue that if you are using the Reader API and you want some level of guarantee of reading the data, you would have to configure retention. If you don't and the Reader dies, the data is not guaranteed to be there when the Reader comes back. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
