Method and system for unified technological stack management for relational databases

摘要

An approach is described for providing unified technological stack management (e.g., via a global storage instance) where metadata is delocalized from storage nodes. The approach includes creating a global storage instance, wherein the global storage instance contains metadata for a storage layer including a plurality of storage nodes, and wherein the global storage instance is delocalized from the plurality of storage nodes. The approach also includes receiving a database operation request from an operating system layer. The approach further includes mediating the database operation request between the operating system layer and the storage layer using the global storage instance.

1. A method comprising:
creating, by an apparatus operated by a service provider, a global storage instance in response to an end user request, wherein the global storage instance contains metadata of a storage layer including all storage nodes operated by the service provider for a plurality of clients, and wherein the global storage instance is delocalized from the storage nodes, wherein the storage layer includes a plurality of data centers at different geographic locations; receiving, by the apparatus, a database operation request from an operating system layer; mediating, by the apparatus, the database operation request between the operating system layer and the storage layer using the metadata of the storage nodes contained in the global storage instance; and upon a completion of the database operation request, initiating, by the apparatus, (1) updates to the metadata of the storage nodes contained in the global storage instance based on metadata locally updated at one or more of the storage nodes that completed the database operation request, (2) a synchronization of file indexes of all of the storage nodes, and (3) an account for and a rebalance of storage space available in all of the storage nodes.
