[Enhancement]: Ability to specify a length for prefixes generated by `name_prefix` type arguments
Terraform Core Version
1.5.1
AWS Provider Version
5.10.0
Affected Resource(s)
aws_cloudwatch_event_rule
Expected Behavior
When creating a rule and using the name_prefix
option to avoid collisions while still composing the name out of several elements, I would expect that the unique suffix appended would be reasonably short, just enough to ensure non-collision, while leaving me with space to produce a meaningful name in the 64 character limit that the rule name field has. A more complex improvement would be to measure the length of the prefix and produce a suffix that is short enough to fit (perhaps throwing an error in the event that there's insufficient space left)
Additionally, at a minimum, if no change is made the documentation should warn about the severely constrained space when using name prefixes.
Actual Behavior
Examining the generated name, it seems that the provider appends a 26-character suffix to the prefix provided, leaving less than 60% of the total space available for the user.
