6.  def automaticallyUpdateProtocolOfExistingTables: Boolean

   Whether the feature can automatically update the protocol of an existing table when the metadata requirements are satisfied.

   Whether the feature can automatically update the protocol of an existing table when the metadata requirements are satisfied. As a rule of thumb, a table feature that requires explicit operations (e.g., turning on a table property) should set this flag to true, while features that are used implicitly (e.g., when using a new data type) should set this flag to false.

18.  def minProtocolVersion: Protocol

    Get a Protocol object stating the minimum reader and writer versions this feature requires.

    Get a Protocol object stating the minimum reader and writer versions this feature requires. For a feature that can only be explicitly supported, this method returns a protocol version that supports table features, either (0,7) or (3,7) depending on the feature is writer-only or reader-writer. For a legacy feature that can be implicitly supported, this method returns the first protocol version which introduced the said feature.

    For all features, if the table's protocol version does not support table features, then the minimum protocol version is enough. However, if the protocol version supports table features for the feature type (writer-only or reader-writer), then the minimum protocol version is not enough to support a feature. In this case the feature must also be explicitly listed in the appropriate feature sets in the Protocol.
