1.4.2 Using EADS as a read cache

You can use EADS as a read cache in application systems. A read cache is memory for storing data temporarily to achieve high-speed data read operations.

The figure below shows an example of a reference application program that uses EADS as a read cache. This example might be for a system that displays customer information and customer purchase histories, such as for an online order fulfillment system.

1. First load the required data, such as a purchase history, from the RDBMS to EADS (read cache).

2. The client accesses EADS and references data.

You can eliminate disk access overhead and achieve high-speed data processing by using EADS as a read cache, without reading data directly from the RDBMS.
