 * Sync Service
 * @description
 *  A Sync is active Nango Sync on the connection level that has:
 *  - collection of sync jobs (initial or incremental)
 *  - sync schedule
 *  - bunch of sync data records
 *
 *  A Sync config is a separate entity that is not necessarily active on the
 *  provider level that has no direction to a sync
 *  A Sync job can connect a sync and a sync config as it has both a `sync_id`
 * and `sync_config_id`
