# `Electric.Replication.PublicationManager.RelationTracker`
[🔗](https://github.com/electric-sql/electric/tree/%40core/sync-service%401.6.2/packages/sync-service/lib/electric/replication/publication_manager/relation_tracker.ex#L1)

Provides interface for shapes to register and deregister themselves
from a publication, and tracks the overall set of relations that need
to be published using reference counting.

Relies on Electric.Replication.PublicationManager.Configurator
to perform the actual publication updates and handles status updates
to reply to shapes requesting to be registered.
