This module attemtps to provide a storage driver that is really multiple storage drivers. This could be used for storage error tolerance or caching of data in a faster storage driver.


An example:

storage = "multi"
storage_multi_policy = "all"
storage_multi = {

Here data would be first read from or written to mod_storage_memory, then internal storage, then SQL storage. For reads, the first successful read will be used. For writes, it depends on the storage_multi_policy option. If set to "all", then all storage backends must report success for the write to be considered successful. Other options are "one" and "majority".


With the plugin installer in Prosody 0.12 you can use:

sudo prosodyctl install --server= mod_storage_multi

For earlier versions see the documentation for installing 3rd party modules
