Re: In every query, carbondata has to scan all the segment file. This may takes too much time.

Hi,
This issue has already been fixed. The segments do not refresh from cache if the segment file name has not been updated.
Please find the solution in the following PR :https://github.com/apache/carbondata/pull/3988
Kindly check the changes in TableStatusReadCommittedScope.java class

Thanks
