Fields

backing_store: BlobdCfgBackingStore

expire_incomplete_objects_after_secs: u64

This must be much greater than zero.

lpage_size_pow2: u8

object_tuples_area_reserved_space: u64

The amount of bytes per partition to reserve for storing object tuples. This can be expanded online later on, but only up to the leftmost heap allocation, so it’s worth setting this to a high value. This will be rounded up to the nearest multiple of the lpage size.

spage_size_pow2: u8

The device must support atomic writes of this size. It’s recommended to use the physical sector size, instead of the logical sector size, for better performance. On Linux, use blockdev --getpbsz /dev/my_device to get the physical sector size.

statsd: Option<Arc<StatsdClient>>

uring_coop_taskrun: bool

Advanced options, only change if you know what you’re doing.

uring_defer_taskrun: bool

uring_iopoll: bool

uring_sqpoll: Option<u32>
