See Also: Constant Field Values CREATE_INDEX public static final String CREATE_INDEX Creates a column (attribute) index, low-cardinality index, chunk skip index, geospatial index, CAGRA index, or HNSW index (depending on the specified INDEX_TYPE), on the column name specified in value. If this column already has the specified index, an error will be returned. See Also: Constant Field Values REFRESH_INDEX public static final String REFRESH_INDEX Refreshes an index identified by INDEX_TYPE, on the column name specified in value. Currently applicable only to CAGRA indices. See Also: Constant Field Values DELETE_INDEX public static final String DELETE_INDEX Deletes a column (attribute) index, low-cardinality index, chunk skip index, geospatial index, CAGRA index, or HNSW index (depending on the specified INDEX_TYPE), on the column name specified in value.

If the schema provided is non-existent, it will be automatically created. See Also: Constant Field Values MOVE_TO_SCHEMA public static final String MOVE_TO_SCHEMA Moves a table or view into a schema named value. If the schema provided is nonexistent, an error will be thrown. If value is empty, then the table or view will be placed in the user's default schema. See Also: Constant Field Values PROTECTED public static final String PROTECTED No longer used. Previously set whether the given tableName should be protected or not. The value would have been either 'true' or 'false'. See Also: Constant Field Values RENAME_TABLE public static final String RENAME_TABLE Renames a table or view to value. Has the same naming restrictions as tables. See Also: Constant Field Values TTL public static final String TTL Sets the time-to-live in minutes of the table or view specified in tableName. See Also: Constant Field Values ADD_COMMENT public static final String ADD_COMMENT Adds the comment specified in value to the table specified in tableName. Use COLUMN_NAME to set the comment for a column.

Use COLUMN_TYPE and COLUMN_PROPERTIES in options to set the column's type and properties, respectively. See Also: Constant Field Values CHANGE_COLUMN public static final String CHANGE_COLUMN Changes type and properties of the column specified in value. Use COLUMN_TYPE and COLUMN_PROPERTIES in options to set the column's type and properties, respectively. Note that primary key and/or shard key columns cannot be changed. All unchanging column properties must be listed for the change to take place, e.g., to add dictionary encoding to an existing 'char4' column, both 'char4' and 'dict' must be specified in the options map. See Also: Constant Field Values SET_COLUMN_COMPRESSION public static final String SET_COLUMN_COMPRESSION No longer supported; action will be ignored. See Also: Constant Field Values DELETE_COLUMN public static final String DELETE_COLUMN Deletes the column specified in value from the table specified in tableName.

See Also: Constant Field Values DELETE_FOREIGN_KEY public static final String DELETE_FOREIGN_KEY Deletes a foreign key. The value should be the foreign_key_name specified when creating the key or the complete string used to define it. See Also: Constant Field Values ADD_PARTITION public static final String ADD_PARTITION Adds the partition specified in value, to either a range-partitioned or manual list-partitioned table. See Also: Constant Field Values REMOVE_PARTITION public static final String REMOVE_PARTITION Removes the partition specified in value (and relocates all of its data to the default partition) from either a range-partitioned or manual list-partitioned table.
