Using multi-readers and writers
Multiple readers and writers are supported to increase disk I/O throughput.
Multiple readers and writers are supported to persist data onto disk. By default, this is set to three total workers per data bucket, with two reader workers and one writer worker for the bucket. This feature helps increase disk I/O throughput. If disk utilization is below the optimal level, increase the setting to improve disk utilization. If disk utilization is near the maximum and heavy I/O contention occurs, decrease this setting. By default, three total readers and writers are allocated.
