MemoryStorageSource (Dev)

Description

The MemoryStorageSource is an in memory NoSQL style storage source. Notifications for changes in the database are also supported.

Services Provided

IStorageSourceService

Service Dependencies

IDebugCounterService
IRestApiService

Java File

The module is implemented in net.floodlightcontroller.storage.memory.MemoryStorageSource.

How it works

Other Floodlight modules that depend upon the IStorageSourceService interface can create/delete/modify data in the memory storage source. All data is shared and there is no enforcement. Modules can also register for changes to data in specific tables and rows. Any module that wants to do this should implement the IStorageSourceListener interface.

Limitations

Since the storage is in memory, when Floodlight is shutdown all state will be lost.
There is no isolation of data enforced. Even if a module created a table another module can overwrite the data.

Configuration

This module is enabled by default, no extra configuration is needed.

Configuration Options

None.
