identifier

public String identifier()

Description copied from interface: Factory

Returns a unique identifier among same factory interfaces.

For consistency, an identifier should be declared as one lower case word (e.g. kafka). If multiple factories exist for different versions, a version should be appended using "-" (e.g. elasticsearch-7).
