All Implemented Interfaces:
Serializable, Comparable<JoinType>
@Experimental public enum JoinType extends Enum<JoinType>
The type/algorithm of join operation. Currently, we only support regular Join (Non-Window Join). Outer joins require the ability to determine when there is no more data for a specific join key, which is not feasible for non-window join over unbounded streams. Therefore, we have only introduced the INNER join type and plan to introduce more join types as needed in the future.

  • Enum Constant Details

    • INNER

      public static final JoinType INNER

  • Method Details

    • values

      public static JoinType[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      Returns:
      an array containing the constants of this enum type, in the order they are declared

    • valueOf

      public static JoinType valueOf(String name)
      Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
      Parameters:
      name - the name of the enum constant to be returned.
      Returns:
      the enum constant with the specified name
      Throws:
      IllegalArgumentException - if this enum type has no constant with the specified name
      NullPointerException - if the argument is null
