摘要： A method includes determining that a trigger condition of a triggered optimization module of a plurality of optimization modules is met and optimizing scalable storage based on an optimization routine. The optimization routine includes providing a plurality of candidate operations and for a selected optimization module of the plurality of optimization modules that has a higher priority than the triggered optimization module, removing a candidate operation from the plurality of candidate operations that would diminish a modeled state of the scalable storage for the selected optimization module. The optimization routine also includes determining at least one operation of the plurality of candidate operations that would improve the modeled state of the scalable storage for the triggered optimization module and updating the modeled state of the scalable storage to model executing the at least one operation. The method further includes executing the at least one operation.

摘要： Various embodiments for implementing garbage collection in distributed storage systems are provided. A distributed storage system operates based on independent management of metadata of extent and stream data storage resources. A hybrid garbage collection system based on reference counting garbage collection operations and mark-and-sweep garbage collection operations is implemented. An extent lifetime table that tracks reference weights and mark sequences for extents is initialized and updated based on indications from extent managers and stream managers, respectively. Upon determining that an extent is to be handed-off from weighted reference counting garbage collection operations to mark-and-sweep garbage collection operations, a reference weight field for the extent is voided and a mark sequence field of the extent is updated. The mark sequence field is updated with a latest global sequence number. Mark-and-sweep garbage collection operations are utilized to reclaim the extent when it is no longer referenced.

摘要： In various embodiments, methods and systems for integrated resource allocation and loading balancing are provided. A global resource allocator receives usage information of resources in a cloud computing system. The usage information is associated with a plurality of accounts and consumer operations pairs on servers of the cloud computing system. For selected account and consumer operation pairs associated with a particular resource, allocation targets are determined and communicated to the corresponding server of the selected account and consumer operation pairs. The servers use the resource based on the allocation targets. A load balancer receives the usage information the resource and the allocation targets. The allocation targets indicate a load by the selected account and consumer operation pairs on their corresponding servers. The load balancer performs a load balancing operation to locate a server with a capacity to process the allocated target of the selected account and consumer operation pairs.

摘要： In various embodiments, methods and systems for providing access to file systems are provided. An SFA-based operation having an operation modifier for a file in a file system is received. The SFA-based operation is defined based on a file-representational state transfer (REST) interface. The SFA-REST interface comprises integrated functionality of an SFA protocol and REST protocol. The SFA-based operation is executed using the operation modifier. A REST-based operation for the file in the distributed file storage is received. The REST-based operation is defined based on the SFA-REST interface. The operation modifier is referenced in order to execute the REST-based operation. The REST-based operation based on the SFA-REST interface. A schema can be implemented for accessing the file system. The schema includes tables to store files, the table comprises fields corresponding to elements of a SFA-REST interface.
