To be able to perform all available operations on your data regions,
follow these region naming guidelines.
- Characters permitted in region names are alphanumeric characters
(`ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789`),
period (`.`), underscore (`_`), square brackets (`[ ]`), hyphen (`-`), caret (`^`) and backquote (`` ` ``).
- Region names are case sensitive.
- Do not use the slash character (`/`).
- Do not begin region names with two underscore characters (`__`),
as this is reserved for internal use.
