A method of managing on-line user data in a table-level distributed database system is disclosed. At a loading interface, a load request from a client device specifying a new or updated data table, which has been populated in a distributed file system, is received. The load request also specifies a location in the distributed file system and a schema of the data table. The loading interface creates new records in a metadata store, and each new record specifies a mapping between the data table and a particular instance that is to load such data table. Each record also specifies the location and schema for such data table. Based on the new records, each instance also loads the data table. Each instance publishes, in the metadata store, load status specifying that loading of the data table is complete so that such data table can be queried by a query client.
