Abstract
In some examples, a first computing device may receive a first request from a second computing device. For example, the first computing device may be able to communicate with a plurality of database nodes, each database node maintaining a portion of a database distributed across the plurality of database nodes. Further, the first computing device may maintain a local cache of a subset of information maintained in the database. The first computing device may send a second request based on the first request to a first database node to cause the first database node to change the data in the database. In addition, the first computing device receives, from a message queue of a plurality of distributed message queues, a cache update message based on the change to the data in the database. The first computing device may update the local cache based on the cache update message.
