Abstract: Techniques and structures relating to processing of data in an information sharing service are disclosed. Implementation of a data structure including entries identifying data that may be shared amongst users in the information service facilitates efficient processing. The data structure entries may include pointers usable to access corresponding details of the sharable data. The entries may also include information useful for filtering the entities, such as an indication of a user account that originates an account update, and a time associated with an update. The data structure may be used to generate data feeds that allow users to access the identified data.
