# Caching Data Structures

## Overview

**Caching**allows users the option to cache data for a specified **Data****Structure.**This allows users to keep an additional copy of the data that can be quickly fetched from the **Data****Cache**rather than utilizing additional system resources required to pull information directly from an object's database table.

---

## Example

The following example will demonstrate how to enable caching on a data structure and add data to the data structure.

1. From a Designer Project, click CREATE DATAYPES/INTEGRATION and click **Database Structure**.
2. On the **Database Structure** window, enter "UserInfo" as the **Structure Type Name**. Under **Name**, enter "Email" and select **String [Text]** as the **Type**. Under the ADVANCED category click the**Enable Caching** checkbox. Click SAVE.

3. From a Designer Project, click CREATE FLOW and select **Flow**. Name the Flow and click CREATE.
4. In the **Toolbox**panel, navigate to **USER DEFINED TYPES > DATABASE STRUCTURES > USERINFO**and attach a **Create UserInfo**step to the **Start**and **End** steps.

5. From the **Properties**panel of the Create step under**INPUTS > Item to Create**, map a **Constant**value (fakeemail@fakeemail.com).![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2025-06-24_10h36_00.png)
6. Click **Save**to save changes to****the Flow, then click **Debug**on the top action bar.****
7. After the Flow runs, select **Create UserInfo > Execution 1 > View Input/Output Data**and verify that the Flow has created the data value as expected.Since the Enable Caching****option was used on the Data Structure, the resulting saved value will be saved to the Database Table of the Data Structure and into a Cache.

## About Entities Steps

Once Enable Caching****is established on a Data Structure, any data retrieved via a **Fetch****Entities**step will be retrieved from the **Data****Cache**rather than the database table itself. This helps to reduce time and system load when fetching the data. Additionally, utilizing the other **Entity**steps (from **Toolbox > DATABASE**), such as **Save****Entities**or **Update****Entity**/**Entities**for a Data Structure with caching enabled, will save the changes to the cache first. It will then push the changes to the Database Table to keep both of them in sync with one another.![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2025-06-24_10h37_15.png)

## Alternate Caching Method

Data Structures can also be Cached by specifying a value directly into a **Put****In****Cache**step and retrieved via a **Get From Cache** step and a **Key**value.

For more information on how to use Cache****steps, including the **Put In Cache** step, see [Cache Steps](/v9/docs/cache-steps).
