Methods
An input table supports the following methods:
add: add data to an input table. The added data must fit the schema of the input table.add_async: add data to an input table asynchronously. The added data must fit the schema of the input table.delete: delete data from an input table. This method can only be used on a keyed input table.delete_async: delete data from an input table asynchronously. This method can only be used on a keyed input table.
Examples
The following example creates an input table from a pre-existing table by using the init_table argument. It does not specify any key columns, which means the result table is append-only.
The following example creates an input table from a dict of column definitions. It does not specify any key columns, which means the result table is append-only.
The third example creates an input table and specifies a key column, so the resulting input table is keyed rather than append-only.
Data can be added to an input table programmatically using the add method.
Data can be added to an input table manually via the UI.
