What does this statement mean?

Number of bytes in a pull request

Users can set a limit on the number of bytes that a consumer can get from a broker, for example, 1 MB. If a consumer tries to get a message larger than 1 MB from the broker, it will get an error. If the number of bytes specified in the pull request is smaller than 1 MB, it will get an error on messages larger than the specified number of bytes. However, if the specified number of bytes is larger than 1 MB, it will return messages whose size stacks up to be equal to or less than the specified limit.

Hi @Jaswant_Golla !!
This statement is referring to the ability of users to control the amount of data a consumer can retrieve from a broker in a single pull request. By setting a limit on the number of bytes, such as 1 MB, users can restrict the maximum size of the response received by the consumer.

If a consumer attempts to fetch a message from the broker that exceeds the specified limit (e.g., larger than 1 MB), an error will be encountered. On the other hand, if the number of bytes specified in the pull request is smaller than the limit, the consumer will receive an error when trying to fetch messages larger than the specified number of bytes.

However, if the specified number of bytes is greater than the limit (e.g., larger than 1 MB), the broker will return messages whose combined size is equal to or less than the specified limit. In other words, it will return as many messages as possible within the given byte limit, prioritizing smaller messages to fit within the specified size constraint.
I hope it helps. Happy Learning :blush:
