/// Use [`Self::table_type()`] to determine the [`TableType`] of the table.

/// # Column ID & Column Index
///
/// [`ColumnId`](risingwave_common::catalog::ColumnId) (with type `i32`) is the unique identifier of
/// a column in a table. It is used to access storage.
///
/// Column index, or idx, (with type `usize`) is the relative position inside the `Vec` of columns.
///
/// A tip to avoid making mistakes is never do casting - i32 as usize or vice versa.
///
/// # Keys
///
/// All the keys are represented as column indices.
///
/// - **Primary Key** (pk): unique identifier of a row.
///
/// - **Order Key**: the primary key for storage, used to sort and access data.
///
///   For an MV, the columns in `ORDER BY` clause will be put at the beginning of the order key. And
///   the remaining columns in pk will follow behind.
///
///   If there's no `ORDER BY` clause, the order key will be the same as pk.
///
/// - **Distribution Key**: the columns used to partition the data. It must be a subset of the order
///   key.
