I have a question about function getOffsetsBefore() in class SimpleConsumer.
I am not sure about the input value of maxNumOffsets.
If I set this value to a small number, I cannot get enough valid Offset
If I set to a big number like 10,000, I think this function will consume a
lot of time.
Right now I set it to 10, but I am not sure if this is a good value.
Is there any advice how to set the value of maxNumOffsets?
