Hi ,
Thank you so much for your quick response.
I have a doubt when you told script.
Are you talking about Shell scripting/ Perl Scripting or any other script.
It 'll be a great pleasure if you can help me with a small example.

If you are interested in the reasons why multiple transactions are needed, just go through DefineIndex() in
indexcmds.c,particularly the comments. It explains all the phases that are happening for a concurrent index build, what
arethe validation phases, what are the wait phases, etc. The same applies for DROP INDEX with index_drop() in index.c.
