 * <p>Much of the power of the multimap API comes from the <i>view collections</i> it provides.
 * These always reflect the latest state of the multimap itself. When they support modification, the
 * changes are <i>write-through</i> (they automatically update the backing multimap). These view
 * collections are:

> **NOTE:** `{1...n}` shown have 3 dots! Using only 2 dots `{1..n}` will be interpreted by your shell and won't be passed to MinIO server, affecting the erasure coding order, which would impact performance and high availability. **Always use ellipses syntax `{1...n}` (3 dots!) for optimal erasure-code distribution**
