Synapse maintains room and user statistics in various tables. These can be used for administrative purposes but are also used when generating the public room directory.

High-Level Concepts


  • subject: Something we are tracking stats about – currently a room or user.
  • current row: An entry for a subject in the appropriate current statistics table. Each subject can have only one.


Stats correspond to the present values. Current rows contain the most up-to-date statistics for a room. Each subject can only have one entry.
