Define Hive Table Index Properties

Use the Hive Table Index Editor to specify properties for a table index in a physical model. For more information about these properties, see your Hive documentation.

To define Hive table index properties

  1. Right-click a table index in the Model Explorer and click Properties.

    The Hive Table Index Editor opens.

  2. Select the table from the Table drop-down that contains the index that you want to define.
  3. Select the index in the Navigation Grid that you want to define.

    Click New New icon in property editors to create a new object on the toolbar to create a new index. Use the Enter filter text box to filter a very large list of indexes to quickly locate the one that you want to define.

  4. Work with the following options:
    Table

    Displays the table to which the selected table index belongs.

    property editor PREVIOUS icon Previous

    Positions the editor on the previous table index in the Navigation Grid.

    property editor NEXT icon Next

    Positions the editor on the next table index in the Navigation Grid.

    Table Index Editor Toolbar_Index Sort Order Button Sort

    Sorts the table indexes by alphabetic, reverse alphabetic, or index order. You select the method you want using the drop-down menu that opens after you click the Sort button.

    New icon in property editors to create a new object New

    Creates a new table index that becomes the current object in the editor.

    property editor DELETE button Delete

    Deletes the selected table index.

    property editor HELP button Help

    Accesses online help for the editor.

    enter filter text box in a property editor to filter object list

    Lets you enter text to filter a large list of table index objects so you can quickly locate the one that you want.

    Show FK Indexes

    Specifies to display FK (foreign key) indexes in the Navigation Grid.

    Physical Name

    Displays the physical name of the table index.

    Type

    Displays the table index type.

    Physical Only

    Specifies whether to have the index appear in the physical model only. If you want the index to appear in the logical model as a key group, clear the check box.

    This option is unavailable when a primary or foreign key index is selected.

    Generate

    Generates SQL during forward engineering. Clear the check box if you do not want to generate SQL.

  5. Click the General tab and work with the following options:
    Index Members

    Specifies the columns for the table that have the index and are key group members. You can select any column to be a key group member. The columns can be sorted.

  6. Click the Options tab and work with the following options:
    Deferred Rebuild

    Indicates that the newly created index is initially empty (regardless of whether the table contains any data).

    Index Type

    Specifies the type of index that you want to create. In other words, it specifies the Hive index class handler.

    Index Properties

    Lets you specify additional table properties.

    Index Table Name

    Hive allows you to store an index as a table. This property specifies the name of the table in which the index will be stored. If not specified, a Hive default name will be used.

    Location

    Indicates that a specific distributed file system directory must be used to store data files.

    Table Properties

    Lets you specify additional table properties.
