Stores

The InfoGrid persistence architecture is built around the Store abstraction.

API

The Store API can be found ​here. It provides operations:

• to initialize the Store
• to put named blobs into the Store
• to update named blobs in the Store
• to get named blobs from the Store
• to delete named blobs, or blobs with names matching a pattern from the Store
• to subscribe to events emitted by the Store.

Subtype ​IterableStore augments these operations with additional operations:

• to determine the size of the Store
• to iterate over the blobs in the Store.

Implementations

InfoGrid provides several implementations of these interfaces, including:

• mapping to several relational database management systems
• mapping to files in a local file system
• mapping to files in a potentially distributed grid
• delegating, with a name prefix, to another Store (PrefixingStore)
• in-memory only (MStore)
• delegating to another Store, encrypting and decrypting the named blob on the fly (EncryptedStore).

Application developers may develop additional implementations of Store.
