When to Use Custom Settings vs Custom Metadata in Salesforce

In Salesforce, both Custom Settings and Custom Metadata Types offer ways to store configuration data, but they serve different purposes and have distinct use cases. Understanding when to use each can significantly enhance your application’s performance and maintainability. Let’s explore the differences, benefits, and best practices for using Custom Settings and Custom Metadata Types.

Understanding Custom Settings

Custom Settings are specialized Salesforce objects that allow you to store custom data for your organization. They are particularly useful for application configuration and can be accessed without the need for SOQL queries.

Types of Custom Settings

1. List Custom Settings: These are similar to custom objects and can hold multiple records. They are ideal for storing data that doesn’t change often.
2. Hierarchy Custom Settings: These allow for different values at different levels (org, profile, user), making them excellent for user-specific configurations.

Benefits of Custom Settings

• Performance: Custom Settings data is cached, which means faster access compared to standard objects.
• Simplicity: They are easy to set up and use, making them a great choice for straightforward configuration needs.
• Profile and User Specificity: Hierarchy settings can provide tailored configurations based on user profiles.

Challenges with Custom Settings

• Limited to 500k records: If you have a large amount of configuration data, you might hit this limit.
• Not Deployable: Custom Settings data cannot be included in change sets or deployed between environments directly.

Understanding Custom Metadata Types

Custom Metadata Types are similar to Custom Settings but offer additional features that enhance their usability and flexibility. They are designed for metadata management rather than just storing configuration data.

Benefits of Custom Metadata Types

• Deployable: Custom Metadata records can be packaged and deployed along with your application.
• Flexible: You can create relationships with other Salesforce objects, which allows for more complex data structures.
• Version Control: You can track changes over time, making it easier to manage different versions of configurations.

Challenges with Custom Metadata Types

• Caching Limitations: Unlike Custom Settings, Custom Metadata Types are not cached in the same way, which might lead to slower access in certain scenarios.
• Complexity: They may require more setup and understanding, especially if you’re new to Salesforce development.

When to Use Custom Settings vs. Custom Metadata

Choosing between Custom Settings and Custom Metadata Types depends on your specific use case. Here are some guidelines:

Use Custom Settings When:

• You need a quick, straightforward solution for storing application settings.
• Your settings do not require deployment across environments.
• You are working with user-specific or profile-specific configurations.
• Performance is a key concern, and you need fast access to frequently used data.

Use Custom Metadata When:

• You want to deploy your configuration data alongside your application.
• You require complex relationships with other Salesforce objects.
• Your configuration data needs to be versioned or tracked over time.
• You are handling a larger amount of configuration data that exceeds the limits of Custom Settings.

Best Practices for Custom Settings and Custom Metadata

For Custom Settings:

• Use Hierarchy Settings Wisely: Leverage the user and profile hierarchy to create customized experiences for different users.
• Limit the Number of Records: Keep your Custom Settings lean to avoid hitting the record limit.
• Regularly Review: Periodically review the settings to ensure they are still relevant and being used.

For Custom Metadata:

• Plan Your Metadata Structure: Before creating Custom Metadata Types, plan the relationships and data structure carefully to avoid complexity later.
• Utilize Packages: Use managed packages to deploy Custom Metadata Types and their records easily.
• Version Control: Take advantage of the version control features for better management of your configurations.

Practical Tips

• Combine Both: In some scenarios, you might find it beneficial to use both Custom Settings and Custom Metadata together, depending on your requirements.
• Documentation: Document your Custom Settings and Custom Metadata Types thoroughly to ensure clarity for future developers or admins.
• Testing: Always test your configurations in a sandbox environment before deploying them to production.

Concluding Summary

Choosing between Custom Settings and Custom Metadata Types in Salesforce is not a one-size-fits-all decision. Each has its own strengths and weaknesses, and understanding these can lead to better performance and maintainability of your Salesforce applications. By carefully considering your specific needs and following best practices, you can make informed choices that benefit your organization.
