When certain fields apart from the defined key fields are
used frequently in select query then for improving
performance related to data fetch, it is advised to create
secondary index, which serves as a mapping, but to keep in
mind the order of fileds in use should be same as defined
in secondary index.
According to me Secondary Index is nothing but if we have 2
tables.First table has primary key,and second table also
have primary key.Then the key of the second table is
nothing but Secondary Index of the First Table.
