The key insight this led to is that ML models are software , derived from data. ML learning systems combine the characteristics of software, e.g. the need for CI/CD pipelines, and of data, e.g. the need to track lineage. Many of the software engineering discipline and controls need to be brought over into an ML context.

When compressed, fixed-length string columns do not store trailing blanks, making them just as efficient as variable-length string columns from a storage point of view. Some of this may be due to somewhat out-of-date considerations like space usage. This is the case when using ALTER COLUMN to change from integer to smallint for example.
