In this video, we explore the powerful OPTIMIZE command in Delta Lake and how it enables file compaction for better data performance in PySpark. As Delta Lake tables grow, they can accumulate numerous small files, which impacts read performance and query execution times. With the OPTIMIZE command, you can compact these files into larger, more manageable files, improving performance significantly.

Topics covered:

Understanding file compaction and why it matters in Delta Lake
Using the OPTIMIZE command in Delta Lake
How file compaction impacts read/write performance in PySpark
Practical examples of running OPTIMIZE with and without Z-Order optimization
Best practices for compaction frequency and configuration in Delta Lake
