Availabilities

Availability requests are made through Redeam by channels and resellers. Often, these requests are made immediately before a hold is placed, to confirm that availability is present prior to making the initial hold request. These "last-minute" availability requests are usually for a single point in time, or for a brief duration (a few hours to a day), and can be made frequently for popular products.

Less frequently, channels and resellers may request weeks, months or even a year of availabilities for a product. This is often done to cache the availabilities locally, providing a faster experience for clients on their platform.

To help ensure low response times on availability requests, Redeam provides a pass-through cache, which will conditionally returned cached values, but always passes the availability request through to the reservation system.

• Channels & resellers can make availability requests through Redeam with a configurable maximum-age property.

  • If any availabilities are cached that match the parameters of the request, and are older than the maximum-age, the cache will wait and attempt to deliver the reservation system's response directly to the caller.

    • If the reservation system takes too long to respond*, Redeam will return any data available in the cache back to the client (even if no data is available).

  • Otherwise, the cached availabilities are returned immediately.

• In both scenarios, Redeam will wait for the reservation system to respond with availabilities, and update its cache with the received values.
