In some consumption patterns, increasing the read-ahead limit can increase consumer throughput where currently the consumer is slower than the producer and falls behind (#14877). This change adds Cuttlefish config for the option in rabbitmq/osiris#198:
stream.read_ahead_limit = 8kiBEDIT: this configuration was updated in #14894 to change the key name to
stream.read_ahead. To configure this on v4.2.1+ or v4.3.x+, use:stream.read_ahead = 8kiB
