Server names(s)

The name of the cache server(s) you are using locally. When the rule is running in CX (DDE) then this will be automatically populated and the value will be ignored.

KeySpace

Tables exist in Keyspace (similar to a database). If the rule is running in DDE then this is automatically populated with the client name within DDE and the value will be ignored.

Table

The name of the table which will be created in Cassandra. If left blank this will be the same as the key field name.

Key

The field that contains the unique key (primary key) which identify items in the cache. e.g. Customer ID or Order ID

Timestamp

The datetime field to be used to offset the expiry times against,

If “Use constant for offset” is selected, the amount of minutes in the future the Timestamp date/time should be entered in which to set the event to expire. In the below example, the rule data is set to expire 30 minutes after the current datetime  (Time stored as UTC). This assumes the field “Time Stamp” contains the current datetime:

The “Use field for offset” can be used to dynamically pass the same value into the plugin based on a field value. In the below example, the data containing the amount of minutes is passed into the plugin using a field called “MinutesIntheFuture”.

Use Single Input Field

If “Use Single Input Field” is selected, the “Input Field” drop down should contain the field containing the JSON that should be passed to the sister rule with a Process Future Events step.

In the below example the input field “message” containing the JSON to expire is passed into the step:

Build JSON From Input Field(s)

If “Build JSON From Input Field(s)” is selected, the JSON that is set to expire will be built from the fields specified in the “Select Fields” tab:

In the above example, the data set to expire will be create a JSON object with the following structure:

{
  "Customer Name": "Joe Bloggs",
  "Email Address": "example@alterian.com"
}
