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.
