yr.ProducerConfig.reserve_size

ProducerConfig.reserve_size: int = 0

Represents the reserved memory size in bytes (B). When creating a producer, an attempt will be made to reserve reserve_size bytes of memory. If the reservation fails, creating the producer will raise an exception. reserve_size must be an integer multiple of page_size and within the range [0, max_stream_size]. If reserve_size is 0, it will be set to page_size. Default value is 0.
