# direct dictionary layout

> A dictionary layout that queries the source directly without caching.

<h2 id="direct">
  direct
</h2>

The dictionary is not stored in memory and directly goes to the source during the processing of a request.

The dictionary key has the [UInt64](/reference/data-types/int-uint) type.

All types of [sources](/reference/statements/create/dictionary/sources/overview#dictionary-sources), except local files, are supported.

Configuration example:

<Tabs>
  <Tab title="DDL">
    ```sql theme={null}
    LAYOUT(DIRECT())
    ```
  </Tab>

  <Tab title="Configuration file">
    ```xml theme={null}
    <layout>
      <direct />
    </layout>
    ```
  </Tab>
</Tabs>

<br />

<h2 id="complex_key_direct">
  complex\_key\_direct
</h2>

This type of storage is for use with composite [keys](/reference/statements/create/dictionary/attributes#composite-key). Similar to `direct`.
