How can I improve my spark performance?
Answer / Prateek Trivedi
To improve Apache Spark's performance, consider the following best practices:
1. Increase memory and cores allocated to the Spark cluster.
2. Optimize data partitioning by setting an appropriate number of partitions.
3. Cache or persist important datasets to keep them in memory.
4. Use coarse-grained transformations that process more data per task.
5. Minimize shuffle operations by filtering and aggregating data beforehand.
