Forgot to mention that in addition to fixing the review comments, I had made an additional change to skip the dead tuple while copying tuples from old bucket to new bucket during split. This was previously not possible because split and scan were blocking operations (split used to take Exclusive lock on bucket and Scan used to hold Share lock on bucket till the operation ends), but now it is possible and during scan some of the tuples can be marked as dead. Similarly during squeeze operation, skipping dead tuples while moving tuples across buckets. -- With Regards, Amit Kapila.
