pub const MESSAGING_SOURCE_TEMPLATE: Key;

Low cardinality representation of the messaging source name.

Source names could be constructed from templates. An example would be a source name involving a user name or product id. Although the source name in this case is of high cardinality, the underlying template is of low cardinality and can be effectively used for grouping and aggregation.

Examples

• /customers/{customerId}
