Jenkins. Auto compaction occurs after a write to a table has succeeded and runs synchronously on the cluster that has performed the write. 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.

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. Databricks dynamically optimizes Apache Spark partition sizes based on the actual data, and attempts to write out 128 MB files for each table partition. The problem appears when I call cache on a dataframe. Auto optimize is particularly useful in the following scenarios: Streaming use cases where latency in the order of minutes is acceptable, MERGE INTO is the preferred method of writing into Delta Lake, CREATE TABLE AS SELECT or INSERT INTO are commonly used operations.
