Hello,

I am new to pig was going through a demo tutorial where this syntax was present, but could not understand why they used the FOREACH operation. Can anyone explain?

The operation FOREACH in Apache Pig is required to apply to each component in a data bag, for which the respective action can be performed to create data items.
