Abstract
The subject technology initiates a reinstallation process of a key-value storage device and locking the key-value storage device. The subject technology performs a bootstrap process for a blob manager and a blob worker. The subject technology performs a restoration process of a storage server. The subject technology applies a set of mutation logs to the storage server. The subject technology unlocks the key-value storage device and enabling network traffic for the key-value storage device.
Claims16
A system comprising:
- at least one hardware processor;
- and
- a memory storing instructions that cause the at least one hardware processor to perform operations comprising:
- initiating a reinstallation process of a key-value storage device and locking the key-value storage device;
- performing a bootstrap process for a blob manager and a blob worker, the performing the bootstrap process comprising performing a read operation of a granule manifest from a blob storage device, the granule manifest corresponding to a latest granule manifest that is readable from the blob storage device;
- performing a restoration process of a storage server, the performing the restoration process comprises:
- determining, using the granule manifest, a key range of a set of granule files, each location of each granule file from the set of granule files, and a set of credentials for accessing the set of files;
- fetching, from the blob storage device, the set of granule files based at least in part on the key range of the set of granule files;
- and
- storing the set of granule files on the storage server, each granule file of the set of granule files corresponding a first maximum version of each granule file as stored on the blob storage device;
- applying a set of mutation logs to the storage server;
- and
- unlocking the key-value storage device and enabling network traffic for the key-value storage device.

- performing a restoration process of a storage server, the performing the restoration process comprises:
- determining, using the granule manifest, a key range of a set of granule files, each location of each granule file from the set of granule files, and a set of credentials for accessing the set of files;
- fetching, from the blob storage device, the set of granule files based at least in part on the key range of the set of granule files;
- and
- storing the set of granule files on the storage server, each granule file of the set of granule files corresponding a first maximum version of each granule file as stored on the blob storage device;
- applying a set of mutation logs to the storage server;
- and
- unlocking the key-value storage device and enabling network traffic for the key-value storage device.

A non-transitory computer-storage medium comprising instructions that, when executed by one or more processors of a machine, configure the machine to perform operations comprising:
- initiating a reinstallation process of a key-value storage device and locking the key-value storage device;
- performing a bootstrap process for a blob manager and a blob worker, the performing the bootstrap process comprising performing a read operation of a granule manifest from a blob storage device, the granule manifest corresponding to a latest granule manifest that is readable from the blob storage device;
- performing a restoration process of a storage server, the performing the restoration process comprises:
- determining, using the granule manifest, a key range of a set of granule files, each location of each granule file from the set of granule files, and a set of credentials for accessing the set of files;
- fetching, from the blob storage device, the set of granule files based at least in part on the key range of the set of granule files;
- and
- storing the set of granule files on the storage server, each granule file of the set of granule files corresponding a first maximum version of each granule file as stored on the blob storage device;
- applying a set of mutation logs to the storage server;
- and
- unlocking the key-value storage device and enabling network traffic for the key-value storage device.
