File-Based Persistence

File-based persistence is a mechanism that uses individual files to store persistent data. If you use file-based persistence you can set broker properties to do the following:

• Compact the data store to alleviate fragmentation as messages are added and removed.

• Synchronize the in-memory state with the physical storage device on every write. This helps eliminate data loss due to system crashes.

• Manage the allocation of messages to data store files and manage the resources needed for file management and storage.

File-based persistence is generally faster that JDBC-based persistence; however, some users prefer the redundancy and administrative control provided by a JDBC-compliant store.
