   ### Is your feature request related to a problem or challenge?
   
   Currently loading metadata will split to two parts, if we enable page index. It will cause heavy load for s3 request when we store parquet file in s3 and without local cache.
   
   This ticket will add support to eager loading page index parquet metadata, combined two loading to one.
