Abstract: A real-time messaging platform allows advertiser accounts to pay to insert candidate messages into the message streams requested by account holders. To accommodate multiple advertisers, the messaging platform controls an auction process that determines which candidate messages are selected for inclusion in a requested account holder's message stream. Selection is based on a bid for the candidate message, the message stream that is requested, and a variety of other factors that vary depending upon the implementation. The process for selection of candidate messages generally includes the following steps, though any given step may be omitted or combined into another step in a different implementation: targeting, filtering, prediction, ranking, and selection.

Abstract: Embodiments are provided for enabling dynamic reallocation of resources in a multi-tenant distributed database. According to certain aspects, a management services module allocates multiple portions of computer resources for respective operation of multiple services by multiple customers. A quality of service (QoS) controller detects that one of the services is attempting to exceed its allocated portion of resources, and identifies an available portion of another allocated portion of resources. In response, the QoS controller causes the management services module to dynamically allocate the available portion to the detected service so that the detected service is able to operate without error or delay.
