Hi All,

Here is the great news about this chain of postings about the V8-V9 ( COMPRESSION ). Yesterday I ran the codes with V8. And here are the outcomes:

1) The datasets size CAME to orginal size( by this I am able to save more than 50GB(yes GB ) ).

2) Regarding time I am able to save time atleast 12hrs of time daily( as we know accessing the large dataset takes more time).

Thanks for all quick and wonderful thoughts on this...just posting these things so that others also will benifit...and can understand how the things are going...

Thanks once again for all, Chandu.
