AutoCompactBase

trait AutoCompactBase extends PostCommitHook with DeltaLogging

A trait for post commit hook which compacts files in a Delta table. This hook acts as a cheaper version of the OPTIMIZE command, by attempting to compact small files together into fewer bigger files.

Auto Compact chooses files to compact greedily by looking at partition directories which have the largest number of files that are under a certain size threshold and launches a bounded number of optimize tasks based on the capacity of the cluster.

    This method returns the type of Auto Compaction to use on a delta table or returns None if Auto Compaction is disabled.

    This method returns the type of Auto Compaction to use on a delta table or returns None if Auto Compaction is disabled. Prioritization:

    1. The highest priority is given to DeltaSQLConf.DELTA_AUTO_COMPACT_ENABLED config. 2. Then we check if the deprecated property DeltaConfigs.AUTO_OPTIMIZE is set. If yes, then we return AutoCompactType.Enabled type. 3. Then we check the table property DeltaConfigs.AUTO_COMPACT. 4. If none of 1/2/3 are set explicitly, then we return None
