Delta cache

Delta cache was renamed - Databricks now calls it Disk cache, as of September 2022.

Delta cache → Disk cache

The name Databricks used for the automatic caching that copies remote Parquet files onto a worker's local SSDs so repeated reads hit fast local storage instead of cloud object storage.

• The name was always a little bit of a lie - it caches remote Parquet files, so it worked on plenty of data that was never a Delta table. 🔗
• This was the second name, not the first: the same feature shipped earlier as the DBIO cache, making the 2022 change the third label for one cache. 🔗
