How to achieve performance tuning in PIG ?
Performance tuning in PIG can be achieved in PIG with the following:
1.We can use Optimization
2. We can use Types. If types are not specified in the load statement, Pig assumes the type of =double= for numeric computations.
3. Pig determine when a field is no longer needed and drop the field from the row.
4.It is fruitful to use filters to reduce the amount of data through pipeline
5.It is better to reduce the operator pipelinbe
