There are many ways to improve the performance of a Hive program. Some of these are as follows:
- Data Structure: We have to select the right data structure for our purpose in a Hive program.
- Standard Library: Wherever possible, we should use methods from standard library. Methods implemented in standard library have much better performance than user implementation.
- Abstraction: At times, a lot of abstraction and indirection can cause slow performance of a program. We should remove the redundant abstraction in code.
- Algorithm: Use of right algorithm can make a big difference in a program. We have to find and select the suitable algorithm to solve our problem with high performance.
