What is the diffrence between Multiload & Fastload interms
of Performance?

Answer Posted / kumar

Multiload can at max 5 tables with non unique secondary
indexes on them. where as in fastload u cannot have
secondary indexes on the table.

In multiload you can insert,update or delete data in
already populated tables whereas in fastload the target
table should be empty.

Multiload works in 5 phases whereas fastload works in two
phases.

If we want to load data into an empty table then fastload
is best option as compared to multiload.
