A set of input parameters for const.
Apply various modifications to a table, view, or collection. The available modifications include the following:
Manage a table's columns–a column can be added, removed, or have its type and properties modified, including whether it is compressed or not.
Create or delete an index on a particular column. This can speed up certain operations when using expressions containing equality or relational operators on indexed columns. This only applies to tables.
Create or delete a foreign key on a particular column.
Manage a range-partitioned or a manual list-partitioned table's partitions.
Set (or reset) the tier strategy of a table or view.
Refresh and manage the refresh mode of a materialized view.
Set the time-to-live (TTL). This can be applied to tables, views, or collections. When applied to collections, every contained table & view that is not protected will have its TTL set to the given value.
Set the global access mode (i.e. locking) for a table. This setting trumps any role-based access controls that may be in place; e.g., a user with write access to a table marked read-only will not be able to insert records into it. The mode can be set to read-only, write-only, read/write, and no access.
Change the protection mode to prevent or allow automatic expiration. This can be applied to tables, views, and collections.

Constructs an AlterTableRequest object with the specified parameters.
[in] | tableName_ | Table on which the operation will be performed. Must be an existing table, view, or collection. |
[in] | action_ | Modification operation to be applied
|
[in] | value_ | The value of the modification, depending on action. For example, if action is add_column, this would be the column name; while the column's definition would be covered by the column_type, column_properties, column_default_value, and add_column_expression in options. If action is ttl, it would be the number of minutes for the new TTL. If action is refresh, this field would be blank. |
[in] | options_ | Optional parameters.
