| - `default_fetch_size` (default = `1048576`): The default number of message bytes to fetch in a request, defaults to 1MB. | ||
| - `max_fetch_size` (default = `0`): The maximum number of message bytes to fetch in a request, defaults to unlimited. | ||
| - `max_fetch_wait` (default = `250ms`): The maximum amount of time the broker should wait for `min_fetch_size` bytes to be available before returning anyway. | ||
| - `max_partition_fetch_size` (default = `1048576`): The default number of message bytes to fetch in a request per partition, defaults to 1MB. If a single record batch is larger than this value, the broker will still return it to ensure the consumer can make progress. This setting only applies while using [`franz-go`](https://github.com/twmb/franz-go). |

A thing we can work as a follow-up is to use human readable formats in documentation.
We can use 1 MiB instead of 1048576

Not a necessity for this PR as there few more places in this README.
