OSS Implementation of a DataJunction Reflection Service

DJ Reflection Service

The reflection service polls the DJ core service for all nodes with associated tables, whether source tables or materialized tables. For each node, it refreshes the node's schema based on the associated table's schema that it retrieves from the query service. It also retrieves the available partitions and the valid through timestamp of these tables and reflects them accordingly to DJ core.

This service uses a celery beat scheduler, with a configurable polling interval that defaults to once per hour and async tasks for each node's reflection.
