A non-relational database may be emulated using a relational database with a distributed data store. A request to access the non-relational database may be received at a frontend for a relational database engine that emulates an interface for a non-relational database engine. The request may be translated into the format for the relational database engine and performed by the relational database engine. The relational database engine may access data for the non-relational database at storage nodes that store the data in a relational table column of non-relational data type.

Emulating a non-relational database on a relational database with a distributed data store

A geographically distributed system using a hybrid, multi-master design is disclosed. The system may use global tables, for which both reads and writes may be performed locally, but with a single region serving as a master region. All strongly consistent reads and writes may be sent to the master region, whereas eventually consistent reads and writes may be performed in any region with a replica. The master region may not be statically assigned but may move from region to region. The master region may be assigned manually by client preference or may be assigned and updated automatically based on the time of day or workload characteristics.

Multi-region, multi-master replication of database tables

Systems, methods, and computer-readable media are disclosed for decoupled selection of content for semi-connected electronic devices. In one embodiment, an example method may include determining a set of candidate content for presentation at a semi-connected device, the set of candidate content comprising first content and second content of at least one content campaign, determining that an impression of the first content was served while the semi-connected device was disconnected from a network, determining that the first content and the second content were eligible for presentation at a first timestamp of a first impression interaction for the impression of the first content, determining a first bid amount for the first content and a second bid amount for the second content at a second timestamp of delivery of the first content to the semi-connected device, and determining a winning bid amount for the first impression interaction using the first bid amount and the second bid amount.
