You can create your own declarative developer frameworks for internal teams, partners, and customers. Rather than building apps from data, you can build apps that are defined and driven by their own types of metadata. Metadata is the information that describes the configuration of each customer’s organization.

4. Custom Metadata
Deployable Objects and Data (including Managed Packages).
Not editable via Apex (but updatable via Metadata API).
Does not count towards query limits.
Public/Protected Visibility in managed package.
Cached after first head.
Complex data types(including lookups, long text area).
10MB org limit.

5. Why CMT and not Custom setting or Custom object?
Key Drivers
Portability
Traceability
Leverage Metadata API deployment tools (change sets).
Eliminate human errors.
Extensibility of architecture to support automated deployments through CI.

9. ❖ Integrating data from External Systems(Salesforce/any other) without a single
line of code.
❖ It enables us to view, search and modify the records of external system from
within salesforce and it sync the data.
❖ One can use any of the following 3 protocols to integrate:
➢ OData 2.0 adapter | 4.0 adapter REST based protocol.
➢ Cross-org adapter REST based protocol.
➢ Custom adapter created via Apex.

12. Sync.
❖ Sync. copies only metadata and it doesn’t copy any data from
external system.
❖ Syncing is a one time process. If external system schema is
changed it doesn’t sync changes automatically to salesforce org,
have to resync the objects.
❖ Data types

13. Limitations:
❖ Maximum external objects per org - 100
❖ Maximum joins per query across external and other types of objects - 4
❖ Maximum new rows retrieved by SOSL and salesforce searches per hour - 1,00,000
❖ Maximum new rows retrieved or created per hour - 50,000
❖ OData callouts per hour for Developer Edition - 1000
❖ OData callouts per hour for Enterprise, Professional, Unlimited - 10,000
❖ Maximum HTTP Request size for OData - 8 MB
❖ Maximum HTTP Response size for OData - 8 MB
❖ External objects doesn’t support following functions:
AVG(), COUNT(field), MIN(), MAX(), SUM(), EXCLUDES,
INCLUDES, LIKE, TYPEOF, WITH, FOR VIEW, FOR REFERENCE, toLabel()
