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.
  • It was not the first name either: the docs record the same feature as the DBIO cache too, so the 2022 change gave one cache at least its third label.
  • Its January 2018 general-availability announcement sold it under yet another name, Databricks Cache, promising scans up to 10x faster without any application code change.
