>
> the fileStatusCache is globally shared cache，refresh is only for one table，so we do not need to invalidateAll entry in fileStatusCache
> {code:java}
>   /** Globally shared (not exclusive to this table) cache for file statuses to speed up listing. */
>   private val fileStatusCache = FileStatusCache.getOrCreate(sparkSession)
> {code}
> {code:java}
>  override def refresh(): Unit = {
>     refresh0()
>     fileStatusCache.invalidateAll()
>   }
> {code}
