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

Answer / shubhangi

Fastload is used to load empty tables and is very fast, can
load one table at a time.

Multiload can load at max 5 tbls at a time and can also
update and delete the data.

Fastload can be used only for inserting data, not updating
and deleting.

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

Answer / 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.

Answer / yuvaevergreen

In terms of speed, fastload would be suitable than mload for
loading an empty table.
But when it comes to multiset tables, mload would be a
better option.
Mload allows use of aggregated values whereas fastload does not.
