Answer / gowthami

getting the same row hash value for the same row(or) two
different primary index values is called hash collision

Answer / tdguy

TD uses hashing algorithm to create hash values. Hash value
for a given input is always unique. However as per the
information given by TD, it seems that there are
possibilities that two different PI values can end in same
hash value. This is rare and i hope most of the TD guys
would not have faced it. Such a condition is called
collision.
