The document discusses custom metadata in Salesforce, including: - Custom metadata provides API access only, with no create, update, or delete functionality. Records can be accessed via SOQL but not related to other objects. - Limits include 10 MB of custom metadata per org, 100 custom metadata types per org, and 50,000 records returned per transaction. - Use cases include app configurations for enterprises and ISVs. - A demo was presented along with a roadmap of future custom metadata features like a native UI and relationship support.

4. __mdt?
• API access only
• No CUD
• Use SOQL to access custom metadata records.
– No relationship !
• Records in managed packages
– Subscribers can’t update custom metadata records that are inside installed managed
packages. To allow subscribers to configure custom metadata that you’ve created, include
the custom metadata type in a managed package and include the records in a separate
unmanaged package.
