Issue Type: Improvement (was: Bug)
> Performance improvements for Fileformat and Presto
> --------------------------------------------------
>
> Key: CARBONDATA-3010
> URL: https://issues.apache.org/jira/browse/CARBONDATA-3010
> Project: CarbonData
> Issue Type: Improvement
> Reporter: Ravindra Pesala
> Priority: Major
>
> When querying data using Spark or Presto while filling the vector, carbondata
> is not well optimized. The major issues are as follows.
> # CarbonData has long method stack for reading and filling out the data to
> vector.
> # Many conditions and checks before filling out the data to vector.
> # Maintaining intermediate copies of data leads to more CPU utilization.
> # Filtering of data twice when using spark's fileformat vector flow and
> presto flow
