filesystem_prefetch_max_memory_usage
Maximum memory usage for prefetches.
Cloud default value: 10% of total memory.
filesystem_prefetch_step_bytes
Prefetch step in bytes. Zero means auto - approximately the best prefetch step will be auto deduced, but might not be 100% the best. The actual value might be different because of setting filesystem_prefetch_min_bytes_for_single_read_task
filesystem_prefetch_step_marks
Prefetch step in marks. Zero means auto - approximately the best prefetch step will be auto deduced, but might not be 100% the best. The actual value might be different because of setting filesystem_prefetch_min_bytes_for_single_read_task
