Traditional retrieval of objects is always as whole entities, i.e GetObject for a 5 GiB object, will always return 5 GiB of data. S3 Select API allows us to retrieve a subset of data by using simple SQL expressions. By using Select API to retrieve only the data needed by the application, drastic performance improvements can be achieved.

You can use the Select API to query objects with following features:

     * {@inheritDoc}
     *
     * @see java.lang.Object#hashCode()
     */
    @Override
    public int hashCode () {
        return Objects.hash(this.server, this.share, this.path, this.pathConsumed);
    }


    /**
     * {@inheritDoc}
     *
     * @see java.lang.Object#equals(java.lang.Object)
     */
    @Override
    public boolean equals ( Object obj ) {

  # - filtering criteria only applies for all source objects match the criteria
  # - configurable notification endpoints
  # - configurable retries for the job (each retry skips successfully previously replaced objects)
  flags:
    filter:
      newerThan: "7d10h31s" # match objects newer than this value (e.g. 7d10h31s)
      olderThan: "7d" # match objects older than this value (e.g. 7d10h31s)

  //   allows any non-core object, as well as PersistentVolumeClaim objects.
  // * While dataSource ignores disallowed values (dropping them), dataSourceRef
  //   preserves all values, and generates an error if a disallowed value is
  //   specified.
  // * While dataSource only allows local objects, dataSourceRef allows objects
  //   in any namespaces.

```

### Existing object replication

Existing object replication as detailed [here](https://aws.amazon.com/blogs/storage/replicating-existing-objects-between-s3-buckets/) can be enabled by passing `existing-objects` as a value to `--replicate` flag while adding or editing a replication rule.

    return ordering.compare(function.apply(left), function.apply(right));
  }

  @Override
  public boolean equals(@CheckForNull Object object) {
    if (object == this) {
      return true;
    }
    if (object instanceof ByFunctionOrdering) {
      ByFunctionOrdering<?, ?> that = (ByFunctionOrdering<?, ?>) object;
      return this.function.equals(that.function) && this.ordering.equals(that.ordering);
    }
    return false;
  }

        return Objects.equals(modelName, other.modelName) && Objects.equals(featureSetName, other.featureSetName)
                && Objects.equals(storeName, other.storeName) && Objects.equals(params, other.params)
                && Objects.equals(activeFeatures, other.activeFeatures);
    }

    @Override
    protected int doHashCode() {

Por exemplo, ele não recebe objetos `datetime`, pois estes objetos não são compatíveis com JSON.

Então, um objeto `datetime` teria que ser convertido em um `str` contendo os dados no formato  <a href="https://en.wikipedia.org/wiki/ISO_8601" class="external-link" target="_blank">ISO</a>.

Da mesma forma, este banco de dados não receberia um modelo Pydantic (um objeto com atributos), apenas um `dict`.

#### Secret Keys

The MinIO server uses an unique, randomly generated secret key per object also known as, Object Encryption Key ([OEK](#oek)). Neither the client-provided SSE-C key nor the KMS-managed key is directly used to en/decrypt an object. Instead, the OEK is stored as part of the object metadata next to the object in an encrypted form. To en/decrypt the OEK another secret key is needed also known as, Key Encryption Key ([KEK](#kek)).
