Optimize and compaction are operations commonly used in Apache Spark for optimizing and improving the performance of data storage and processing. Databricks, which is a cloud-based platform for Apache Spark, provides support for these operations on various runtime versions.
Here are some runtime versions in Databricks that support optimize and compaction:
- Databricks Runtime 7.2 and later versions: Databricks Runtime 7.2 introduced a new feature called Delta Lake Auto Optimize, which enables automatic optimization and compaction of Delta Lake tables based on a set of predefined rules. This feature is available in all later versions of Databricks Runtime as well.
- Databricks Runtime 6.4 and later versions: Databricks Runtime 6.4 introduced the OPTIMIZE command for Delta Lake tables, which enables manual optimization and compaction of Delta Lake tables.
- Earlier runtime versions: Optimize and compaction are not available in earlier versions of Databricks Runtime. If you're using an earlier version, you can consider upgrading to a later version to take advantage of these features.
