There is separate property for max rate , by default is is not set, so if you want to limit the max rate you should provide that property a value.
Initial rate =10 means it will pick only 10 records per receiver in the batch interval when you start the process. Depending upon the consumption rate it will increase the consumption of records for processing in each batch. However i, feel 10 is way to low number for 32 partitioned kafka topic.
