Treasure Data's real-time attributes allow you to create and store attributes used in real-time interactions, capture customer behaviors and actions, and ultimately create an updated view of the customer.

These real-time attributes can be used in real-time triggered activations to build better logic and decisioning based on customers' actions.
RT 2.0 supports five real-time attribute types:
- Single-value attribute : An attribute to store a single value. For example, name, age, address, last purchase amount, etc.
- List attribute : An attribute that stores a list of values.
- Counter attribute : An attribute that can keep count of events/actions, including the capability to define sub-counters for smaller time periods.
- Import Batch : Use the Import Batch option to import batch attributes into your real-time platform. If a real-time value is not updated, single-value and counter attributes can be substituted with batch attributes by configuring batch backfill.
- Lookup Catalog : Reference external business data — such as product catalogs, coupon definitions, or sale schedules — keyed by a non-user dimension (for example,
product_id). Unlike other attribute types that store per-user values, Lookup Catalog data is uploaded from thecdp_lookup_catalogdatabase via a Treasure Workflow sync workflow and queried at request time. Lookup Catalog attributes can be used in Entry Criteria and Personalization Payloads just like other attribute types.
