> When the metadata index lookups is done for several thousands of keys, the keys are looked up in metadata table partitions in a serial fashion key by key, leading to the overall delay in the index lookup.
>  # When the indexes are laid out in multiple file groups, the lookup can be parallelized at the filegroup level
>  # Even within a single filegroup, sorted keys can be split and the lookup can be done in parallel.
