1 Answer

There are many ways to improve the performance of a Hive program. Some of these are as follows:

1. Data Structure: We have to select the right data structure for our purpose in a Hive program.

2. Standard Library: Wherever possible, we

 

should use methods from standard library. Methods implemented in standard library have much better performance than user implementation.

3. Abstraction: At times, a lot of abstraction and indirection can cause slow performance of a program. We should remove the redundant abstraction in code.

4. 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.
