Access Custom Metadata Type data without Using the SOQL in Salesforce

From Spring'21 onwards we can get the custom metadata record information without using the SOQL.

Demo:

For the demo, I created the Country and Amount(Country_And_Amount__mdt) Custom Metadata type object and records.

Country_And_Amount__mdt object.

Sample Code:

// Getting all metadata values 
Map<String, Country_And_Amount__mdt> mapValues = Country_And_Amount__mdt.getAll();

for(Country_And_Amount__mdt mdt : mapValues.values()) {
    System.debug('Name => '+mdt.Label);
    System.debug('DeveloperName => '+mdt.DeveloperName);
    System.debug('Amount__c => '+mdt.Amount__c);
}


// Getting metadata record based on value
Country_And_Amount__mdt objMdt = Country_And_Amount__mdt.getInstance('United_States');
System.debug('objMdt => '+objMdt);
