Abstract: Techniques are disclosed relating to multi-tenant database systems with underlying key/value storage. In some embodiments, a computing system generates first logical table information for a first portion of a multi-tenant dataset corresponding to a first tenant and second logical table information for a second portion of the dataset corresponding to a second tenant. The system may store the first and second logical tables using non-relational key/value data structures in one or more storage elements, including: storing entries from the first logical table across a first set of multiple key/value store buckets and storing entries from the second logical table across a second set of multiple key/value store buckets. Disclosed techniques may reduce performance issues due to hotspots while allowing efficient data access for a given tenant by limiting the number of buckets per tenant, relative to traditional techniques.

Abstract: Techniques are disclosed relating to database schemas. A computer system may receive a metadata document that describes an updated schema for a database that stores a plurality of records. The computer system may instantiate a set of processes to perform an upgrade routine to upgrade ones of the plurality of records to comply with the updated schema. While the set of processes are upgrading the records, the computer system may receive a request to perform an operation on one of the plurality of records. The computer system may detect that the record corresponds to an earlier schema version than a version of the updated schema of the metadata document and may upgrade the record to comply with that updated schema. After upgrading the record, the computer system may perform the requested operation on the record.

Abstract: Techniques are disclosed relating to handling queues. A server-based platform, in some embodiments, accesses queue information that includes performance attributes for a plurality of queues storing one or more messages corresponding to one or more applications. In some embodiments, the platform assigns, based on the performance attributes, a corresponding set of the plurality of queues to each of a plurality of processing nodes of the platform. In some embodiments, the assigning of a corresponding set of queues to a given one of the plurality of processing nodes causes instantiation of: a first set of one or more dequeuing threads and a second set of one or more processing threads. The dequeuing threads may be executable to dequeue one or more messages stored in the corresponding set of queues. The processing threads may be executable to perform one or more tasks specified in the dequeued one or more messages.

Abstract: Techniques are disclosed relating to updating schema information for multi-tenant databases. In some embodiments, a multi-tenant database system stores a standard schema for a database object, where the standard schema is shared by multiple tenants and a tenant-specific schema for the database object. The tenant-specific schema may include one or more tenant-specific custom elements for the database object. The system may enforce a naming scheme in which tenant-specific elements include a predetermined pattern that is not included in object elements of the standard schema. The system may, in response to detecting an update of the standard schema, automatically propagate the update to the tenant schema, while the tenant is online.

Abstract: A multi-tenant computer system authenticates access to a shared datastore by a shared service running on the multi-tenant computer system. The shared service is operable to access the shared datastore to execute requests from a plurality of multi-tenant cloud computing services. The requests include an indication of a particular tenant and a particular tenant grouping indicator. Requests are authenticated by cryptographically verifying the request and verifying that the particular tenant is associated with the particular tenant grouping indicator. In response to authenticating a request, the shared service accesses the shared datastore to execute the first request.
