> Issue Type: Improvement
> Reporter: Manish Gupta
> Assignee: Manish Gupta
> Priority: Minor
>
> 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.
