The blobstore super block now contains a bstype field to identify the type of the blobstore. Existing code should be updated to fill out bstype when calling spdk_bs_init() and spdk_bs_load(). spdk_bs_destroy()
Blobstore Block Device: A block device allocated by the SPDK Blobstore, this is a virtual device that VMs or databases could interact with. These devices enjoy the benefits of the SPDK infrastructure, meaning zero locks and incredibly scalable performance. Blobstore Block Device:由SPDK Blobstore分配...
其主要原理是减少了VM中断等事件的数目(例如interrupt,和VM_EXIT),并缩短了host OS中的I/O栈;(3) SPDK加速数据库存储引擎。通过实现了RocksDB中的抽象文件类,SPDK的blobfs/blobstore目前可以和Rocksdb集成,用于在NVMe SSD上加速实现RocksDB引擎的使用。该操作的实质是bypass kernel文件系统将完全使用基于SPDK的用户态...
