# topic.ini The `topic.ini` config file, located at `/etc/squirro/topic.ini` configures the workings of the topic API, one of the core services of the Squirro platform. ## Enable Read / Starred flags To be able to query for read/starred items in a project, the corresponding configuration option needs to contain the project IDs. This is done as a performance optimisation, and enabling this option will have a slight performance impact. ```text [topic] # For caching reasons the read/starred flags aggregations are now disabled # by default. You can enable it by configuring a project id here. # Mulitple ids can be provided by comma-separating them. enable_flags_for_project_ids = XW1vSnxiRp-O4XCvJrA5Jg ```
