### Accessing configuration

All configuration changes can be made using [`mc admin config` get/set/reset/export/import commands](https://github.com/minio/mc/blob/master/docs/minio-admin-complete-guide.md).

   * serial access, it is critical that <b>all</b> access to the backing table is accomplished
   * through the returned table.
   *
   * <p>It is imperative that the user manually synchronize on the returned table when accessing any
   * of its collection views:
   *
   * {@snippet :
   * Table<R, C, V> table = Tables.synchronizedTable(HashBasedTable.<R, C, V>create());
   * ...
