> Whenever a query is executed, dictionary for columns queried is loaded in memory. For
incremental loads dictionary values are loaded incrementally and thus one list contains several
sub lists with dictionary values.
> The dictionary values on incremental load may not be equally distributed in the sub buckets
and this might increase the search time of a value if there are too many incremental loads.
> Therefore the dictionary values should be divided equally in the sub buckets.
