@jackylk please review i have corrected the data rentention test cases and
club the TestInsertUpdateConcurrentTest and TestInsertOverwriteAndCompaction
test case but even after taking the future out in all test cases,test cases of
TestInsertUpdateConcurrentTest is failing randomly only in ci not on local may
be because any one of the two threads one which is running update and other one
which is executing insert overwrite get executed first which is not correct
scenario insert overwrite must get executed first. please suggest?
