Milind Bhandarkar commented on PIG-856:
---------------------------------------
+1 to Sathosh to documenting Knobs. Better to add and document knobs rather
than modify language like this:
{code}
%TempReplicate 2
store A into PigStorage('\t') with replication 2;
{code}
> PERFORMANCE: reduce number of replicas
> --------------------------------------

> Key: PIG-856
> URL: https://issues.apache.org/jira/browse/PIG-856
> Project: Pig
> Issue Type: Improvement
> Affects Versions: 0.3.0
> Reporter: Olga Natkovich
>
> Currently Pig uses the default number of replicas between MR jobs. Currently,
> the number is 3. Given the temp nature of the data, we should never need more
> than 2 and should explicitely set it to improve performance and to be nicer
> to the name node.
