4.  val AUTO_OPTIMIZE: DeltaConfig[Option[Boolean]]

   Whether this table will automatically optimize the layout of files during writes.

5.  val CHANGE_DATA_FEED: DeltaConfig[Boolean]

   Enable change data feed output.

   Enable change data feed output. When enabled, DELETE, UPDATE, and MERGE INTO operations will need to do additional work to output their change data in an efficiently readable format.

6.  val CHECKPOINT_INTERVAL: DeltaConfig[Int]

   How often to checkpoint the delta log.

7.  val CHECKPOINT_RETENTION_DURATION: DeltaConfig[CalendarInterval]

   The shortest duration we have to keep checkpoint files around before deleting them.

   The shortest duration we have to keep checkpoint files around before deleting them. Note that we'll never delete the most recent checkpoint. We may keep checkpoint files beyond this duration until the next calendar day.

8.  val CHECKPOINT_WRITE_STATS_AS_JSON: DeltaConfig[Boolean]

   When enabled, we will write file statistics in the checkpoint in JSON format as the "stats" column.

9.  val CHECKPOINT_WRITE_STATS_AS_STRUCT: DeltaConfig[Option[Boolean]]

   When enabled, we will write file statistics in the checkpoint in the struct format in the "stats_parsed" column.

   When enabled, we will write file statistics in the checkpoint in the struct format in the "stats_parsed" column. We will also write partition values as a struct as "partitionValues_parsed".

10.  val COLUMN_MAPPING_MAX_ID: DeltaConfig[Long]

    Maximum columnId used in the schema so far for column mapping.

    Maximum columnId used in the schema so far for column mapping. Internal property that cannot be set by users.

11.  val COLUMN_MAPPING_MODE: DeltaConfig[DeltaColumnMappingMode]
12.  val DATA_SKIPPING_NUM_INDEXED_COLS: DeltaConfig[Int]

    The number of columns to collect stats on for data skipping.

    The number of columns to collect stats on for data skipping. A value of -1 means collecting stats for all columns. Updating this conf does not trigger stats re-collection, but redefines the stats schema of table, i.e., it will change the behavior of future stats collection (e.g., in append and OPTIMIZE) as well as data skipping (e.g., the column stats beyond this number will be ignored even when they exist).

13.  val ENABLE_EXPIRED_LOG_CLEANUP: DeltaConfig[Boolean]

    Whether to clean up expired checkpoints and delta logs.

14.  val ENABLE_FULL_RETENTION_ROLLBACK: DeltaConfig[Boolean]

    If true, a delta table can be rolled back to any point within LOG_RETENTION.

    If true, a delta table can be rolled back to any point within LOG_RETENTION. Leaving this on requires converting the oldest delta file we have into a checkpoint, which we do once a day. If doing that operation is too expensive, it can be turned off, but the table can only be rolled back CHECKPOINT_RETENTION_DURATION ago instead of LOG_RETENTION ago.

15.  val IS_APPEND_ONLY: DeltaConfig[Boolean]

    Whether this Delta table is append-only.

    Whether this Delta table is append-only. Files can't be deleted, or values can't be updated.

16.  val LOG_RETENTION: DeltaConfig[CalendarInterval]

    The shortest duration we have to keep delta files around before deleting them.

    The shortest duration we have to keep delta files around before deleting them. We can only delete delta files that are before a compaction. We may keep files beyond this duration until the next calendar day.

17.  val MIN_READER_VERSION: DeltaConfig[Int]

    The protocol reader version modelled as a table property.

    The protocol reader version modelled as a table property. This property is *not* stored as a table property in the Metadata action. It is stored as its own action. Having it modelled as a table property makes it easier to upgrade, and view the version.

19.  val RANDOMIZE_FILE_PREFIXES: DeltaConfig[Boolean]

    Whether to use a random prefix in a file path instead of partition information.

    Whether to use a random prefix in a file path instead of partition information. This is required for very high volume S3 calls to better be partitioned across S3 servers.

20.  val RANDOM_PREFIX_LENGTH: DeltaConfig[Int]

    Whether to use a random prefix in a file path instead of partition information.

    Whether to use a random prefix in a file path instead of partition information. This is required for very high volume S3 calls to better be partitioned across S3 servers.

21.  val SAMPLE_RETENTION: DeltaConfig[CalendarInterval]

    The shortest duration we have to keep delta sample files around before deleting them.

22.  val SYMLINK_FORMAT_MANIFEST_ENABLED: DeltaConfig[Boolean]
23.  val TOMBSTONE_RETENTION: DeltaConfig[CalendarInterval]

    The shortest duration we have to keep logically deleted data files around before deleting them physically.

    The shortest duration we have to keep logically deleted data files around before deleting them physically. This is to prevent failures in stale readers after compactions or partition overwrites.

    Note: this value should be large enough: - It should be larger than the longest possible duration of a job if you decide to run "VACUUM" when there are concurrent readers or writers accessing the table. - If you are running a streaming query reading from the table, you should make sure the query doesn't stop longer than this value. Otherwise, the query may not be able to restart as it still needs to read old files.

24.  val TRANSACTION_ID_RETENTION_DURATION: DeltaConfig[Option[CalendarInterval]]

    The shortest duration within which new Snapshots will retain transaction identifiers (i.e.

    The shortest duration within which new Snapshots will retain transaction identifiers (i.e. SetTransactions). When a new Snapshot sees a transaction identifier older than or equal to the specified TRANSACTION_ID_RETENTION_DURATION, it considers it expired and ignores it.
