This can be thought of as analogous to Nagle’s algorithm in TCP. This setting accomplishes this by adding a small amount of artificial delay that is, rather than immediately sending out a record the producer will wait for up to the given delay to allow other records to be sent so that they can be batched together. However in some circumstances the client may want to reduce the number of requests even under moderate load.
Normally this occurs only under load when records arrive faster than they can be sent out. The producer groups together any records that arrive in between request transmissions into a single batched request.
