1 Connection to databricks works fine, working with DataFrames goes smoothly (operations like join, filter, etc). After an individual write, Databricks checks if files can further be compacted, and runs an OPTIMIZE job (with 128 MB file sizes instead of the 1 GB file size used in the standard OPTIMIZE) to further compact files for partitions that have the most number of small files. Do I need to schedule OPTIMIZE jobs if auto optimize is enabled on my table? How do I simplify/combine these two methods for finding the smallest and largest int in an array?

If your cluster has more CPUs, more partitions can be optimized. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. If you have a streaming ingest use case and input data rates change over time, the adaptive shuffle will adjust itself accordingly to the incoming data rates across micro-batches. However, when the size of the memory reference offset needed is greater than 2K, VLRL cannot be used. When set to legacy or true, auto compaction uses 128 MB as the target file size.
