12.2. File Cache Stores

JBoss Data Grid includes one file system based cache store: the FileCacheStore.

The FileCacheStore is a simple, file system based implementation.

Due to its limitations, FileCacheStore can be used in a limited capacity in production environments. It should not be used on shared file system (such as NFS and Windows shares) due to a lack of proper file locking, resulting in data corruption. Furthermore, file systems are not inherently transactional, resulting in file writing failures during the commit phase if the cache is used in a transactional context.

The FileCacheStore is ideal for testing usage and is not suited to use in highly concurrent, transactional or stress-based environments.
