A parameter template is used to manage and apply parameter configurations to LogService clusters in batches. You can create a parameter template, define a set of parameter values, and then select to apply this template when creating a new cluster.
Note
Parameter templates can only be applied when creating a new cluster. After a cluster is created, you cannot modify its parameters via a template; you must use the Parameter Management feature to modify cluster parameters individually.
