Does Pig have the plan to support for loop ?

[zjffdu <zj...@gmail.com>]

Hi all,

 

Since Pig-Latin is script language, will it support the for loop in the
future? Because these days, I am generating a bunch of report based on the
same scripts, just a little different in the parameter. And I use the java
api of pig, then I can simulate the for loop. But there is a disadvantage
that I have to load the data each time, and it will cost a lot of time.

 

So if pig can support the for loop internally, it would be better.

 

 

 

Best regards,

Jeff Zhang

Hi Jeff,

This is a topic of an ongoing debate - whether PigLatin should become a
full scripting language or whether bindings into other scripting
languages such as Python and/or Perl should be provided. The advantage
of the first approach is one stop shopping. The disadvantages the
complexity of the implementation of a full language and also, does the
world really need another scripting language.
