Abstract: Systems, methods, and computer-readable media are disclosed for digital photo frames with personalized content. In one embodiment, an example device may include at least one memory that stores computer-executable instructions, and at least one processor configured to access the at least one memory and execute the computer-executable instructions to determine a human face in an ambient environment, determine a user identifier associated with the human face, and determine a database index comprising relationships between media content and user identifiers. The at least one processor may be configured to determine a set of media content available to the device, the set of media content comprising pre-indexed images and videos, determine first media content of the set of media content associated with the user identifier in the database index, and initiate presentation of the first media content at a display in the ambient environment.

Abstract: Transaction data is written to one or more records in a datastore using key-value pairs. The record key for a record comprises a hash key and a range key, where the hash key corresponds to a particular transaction and the range key corresponds to a transaction type. The record key also comprises a counter to distinguish between different records storing data for the same transaction. A serialized data stream of transaction data may be apportioned into multiple data records and stored in a non-relational datastore. Each record for a transaction is individually readable, independently of the other records for the transaction. Accordingly, data records storing a large amount of transaction data for a transaction may be individual retrieved and presented at an access device, enabling a paginated view of the large amount of data with low latency in its retrieval.
