Structs

• ColumnMetadata
  Each column has a metadata block that is placed at the end of the file. These may be read individually to allow for column projection.
• DeferredEncoding
  The deferred encoding is used to place the encoding itself in a different part of the file. This is most commonly used to allow encodings to be shared across different columns. For example, when writing a file with thousands of columns, where many pages have the exact same encoding, it can be useful to cut down on the size of the metadata by using a deferred encoding.
• DirectEncoding
  The encoding is placed directly in the metadata section
• Encoding
  An encoding stores the information needed to decode a column or page
