Custom data is stored in CloudBilling in the form of generic tables. This facility allows the use of important tabular information to be used in conditions and expressions in the Price Rules. It is possible to store many different "Custom Data Tables" within CloudBilling, with the following key concepts:
Once a table has been added, it can be filled with data. This is done by adding rows to it, by defining a value for each column. The data in these tables can then be used in expressions on your rules. See Price Rules for more information on this subject.
Only columns of type Date can be specified as TTL columns. When a table has a TTL column specified and a TTL length of, e.g., 4 (days), it means that as soon as the date specified in this column for a given row is more than 4 days in the past, the row is removed from the table. This mechanism can be used to keep tables that are frequently or automatically added to, small and relevant.
