- COMPRESSION_TYPE: When setting column compression (set_column_compression for action), compression type to use: none (to use no compression) or a valid compression type. Supported values:
  The default value is SNAPPY.
- COPY_VALUES_FROM_COLUMN: please see add_column_expression instead.
- RENAME_COLUMN: When changing a column, specify new column name.

  - TRUE: true
  - FALSE: false
  The default value is TRUE.
- UPDATE_LAST_ACCESS_TIME: Indicates whether need to update the last_access_time. Supported values:
  - TRUE
  - FALSE
