Iceberg employs internal metadata management that keeps track of data and empowers a set of rich features at scale. Moreover, many customers are looking for an architecture where they can combine the benefits of a data lake and a data warehouse in the same storage location. The Iceberg table is synced with the AWS Glue Data Catalog.

In order to provide these benefits, OpenSearch is designed as a high-scale distributed system with multiple independent instances indexing data and processing requests. Other customers require high durability and as a result need to maintain multiple replica copies, resulting in higher operating costs for them.

The result is made available to the application by querying the latest snapshot. The snapshot constantly updates through stream processing; therefore, the up-to-date data is provided in the context of a user prompt to the model. This allows the model to adapt to the latest changes in price and availability.
