[CARBONDATA-2313] fixed issue in query when multiple sdk writer's outâ¦
problem: [Non-tranactional table] issue in query when multiple sdk writer's
ouput files with same column name with same UUID is placed in single path
scenario: copy one set of sdk writer output, do select query. copy other
set of sdk writer output with same column name and same UUID, do select query.
select query result's only first sets output.
root cause : segment map was not updated with the latest files , if it is
new files placed belong to same segment.
solution: refresh the segment map, if there is a change in list of
carobnindex files during each query for non transactional tables.
