If the Table is small and having the records which are less than the no.of amps , then in this case , then skewness or improper distribtuion is bound to happen across the amps.
is there any way out that we can handle this ?
if a table is small then you do not need to worry about skew. It is unavaidable to have some skew and you do not need to worry about measuring it until you have at least several thousand rows per amp. The impact is minimal unless of course your PI is poorly chosen and all the data is on one amp.
