Explanation:
Auto Optimize is a Delta Lake feature designed to automatically compact small data files within Delta tables during individual writes. It encompasses two main operations: Optimized writes, which aims to produce 128 MB files for each table partition, and Auto compaction, which evaluates if further compaction is possible post-write, executing an OPTIMIZE job with 128 MB file sizes if applicable. This enhances efficiency and performance. For more details, visit Delta Lake documentation.
