Description:
As GigaSpaces/OpenSpaces offers the chance of having 3rd-party persistent solutions for data stored in a space (or a grid as some may say), this extension is to explore the possibility of using Amazon SimpleDB as a storage option. Hibernate data source has already covered much ground for using common relational databases, but there are still occasions in which a normal database is either unavailable or unreliable. For example when running GigaSpaces with Amazon EC2, persistent storage for structured data is just like last piece of the puzzle until SimpleDB is released; another example is for handling high throughput when normal database is just not designed to do the job. This extension runs in a similar way as Hibernate data source which does OR mappings and stores object data in a relational structure. The difference is also fundamental as SimpleDB is not a traditional database and only supports limited data types and ranges. This makes the implementation difficult because of that, but also simple as most object data eventually turn into text represented in different ways in SimpleDB.
