Indexing into SOLR is controlled by an indexing daemon: aidxd. This daemon probes PostgreSQL for available load-id(s) to index. This "queue" is represented by the table reporting.t_client_index_process. See Data Warehouse Design for more information on the structure of this table.

The indexing daemon aidxd recognizes this as an available load-id and begins the indexing process for that particular load-id.
