Abstract
Techniques are disclosed relating to methods that include receiving, by a computer system in a multi-tenant database service, a stream of change event records for a database on a server. A given change event record may be indicative of a modification made to the database by one of a plurality of tenants. The methods may further include storing the received change event records in one or more buffers, and tracking, in a data structure separate from the one or more buffers. Information for ones of the stored change event records may include a corresponding order of reception and a particular tenant associated with a respective change event record. In response to receiving a query from a given tenant, the methods may include processing the query using the data structure to identify change event records associated with the given tenant.
