TopLink Grid enables a new way to scale out JPA applications using Oracle Coherence. TopLink Grid provides applications with a number of options on how they can scale ranging from using Coherence as a distributed shared (L2) cache up to directing JP QL queries to Coherence for parallel execution across the grid to reduce database load. And with TopLink Grid, developers don't have to rewrite their applications to scale out. They can leverage their investment in JPA and still take advantage of the scalability of Coherence.
TopLink Grid Features:
Simple configuration using annotations or XML configuration that align with standard JPA.
The ability to store complex object graphs with relationships in Coherence.
Ability to seletively choose which entities are stored in the grid and which are stored directly in the backing database.
Support for execution of JP QL queries in the Grid or directly against the database
Support for storing Entities with both eager and lazy relationships into Coherence
