Increase the number of input partitions to maximize parallelism and potentially improve query performance, without considering the impact on resource consumption.

Decrease the number of input partitions to reduce resource consumption and improve query performance, by finding an optimal balance between parallelism and resource usage.

Implement file concatenation or bucketing strategies to reduce the number of small files, which indirectly addresses the symptoms of over-partitioning but not the root cause.

Apply partition pruning techniques to selectively read only the necessary partitions, which improves query performance but does not directly reduce the overhead of over-partitioning.
