Subj: | | Help with compression analysis |
|
From: | | Mani, Vijay |
Hi,
Can someone help me with the compression analysis?
I would need some info on how to determine the compression values. For example please find below some sample data. ?I am not sure if I can go
by applying compression on top 3 ranks. Can someone guide me on this?
Number of
COLUMNNAME VALUE records RANK
CPN_RWRD_QL_ACC_ISO_PROD_TP_CD ? 2 ?
CPN_RWRD_QL_ACC_ISO_PROD_TP_CD 20 51,234 1
CPN_RWRD_QL_ACC_ISO_PROD_TP_CD 33 8,569 2
CPN_RWRD_QL_ACC_ISO_PROD_TP_CD 10 1,519 3
CPN_RWRD_QL_ACC_ISO_PROD_TP_CD 34 626 4
Thanks,
Vijay Mani
