- def canMergeSchema: Boolean
Whether the user has enabled auto schema merging in writes using either a DataFrame option or SQL Session configuration.
Whether the user has enabled auto schema merging in writes using either a DataFrame option or SQL Session configuration. Automerging is off when table ACLs are enabled. We always respect the DataFrame writer configuration over the session config.
- def canOverwriteSchema: Boolean
Whether to allow overwriting the schema of a Delta table in an overwrite mode operation.
Whether to allow overwriting the schema of a Delta table in an overwrite mode operation. If ACLs are enabled, we can't change the schema of an operation through a write, which requires MODIFY permissions, when schema changes require OWN permissions.

- def rearrangeOnly: Boolean
Whether to write new data to the table or just rearrange data that is already part of the table.
Whether to write new data to the table or just rearrange data that is already part of the table. This option declares that the data being written by this job does not change any data in the table and merely rearranges existing data. This makes sure streaming queries reading from this table will not see any new changes
