GlobalTempViewManager

class GlobalTempViewManager extends AnyRef

A thread-safe manager for global temporary views, providing atomic operations to manage them, e.g. create, update, remove, etc.

Note that, the view name is always case-sensitive here, callers are responsible to format the view name w.r.t. case-sensitive config.
