Abstract: A non-relational database system may handle requests to access separately stored items in different data stores. An access request for an item may be received that is stored in a table of a non-relational database. If the item is determined to be stored at a data store not implemented as part of the non-relational database, then an instruction to access the item may be sent to a query engine that can access the data store. A result from the second query engine may be used to respond to the access request for the item.

Abstract: Various embodiments are described for tracking and enabling access to information about key access patterns for database tables managed by a database service of a service provider network. Storage nodes can store data as key-value pairs (or key-document pairs), where the records or documents of a database are addressed by a unique key for each record. The storage nodes over time receive requests to perform various operations (for example, to get, put, update, or delete data in a table) associated with records stored by the storage nodes. Key access information extractors collect information regarding the keys accessed and send the information to a key tracking service. Key tracker nodes of the service can collect the data and send it to aggregator nodes. The aggregator nodes can determine a frequency with which such requests are received for keys of a partition or table to which the aggregator node is assigned.

Abstract: Techniques are described for monitoring and enabling access to information about key access patterns for nonrelational database tables managed by a nonrelational database service of a service provider network. Storage nodes store data as key-value pairs (or key-document pairs), where the records or documents of a database are addressed by a unique key for each record. The storage nodes over time receive requests to perform various operations (for example, to get, put, update, or delete data in a table) associated with records stored by the storage nodes. The storage nodes collect information indicating a frequency with which such requests are received for each key for which a storage node is responsible. This frequency information for each key can be normalized relative to a maximum frequency supported by the storage nodes to obtain an access frequency score, where the maximum frequency indicates a frequency at which additional requests to the storage node may be throttled.
