box.session.type()

box.session.type()¶

Return:	the type of connection or cause of action.
Rtype:	string

Possible return values are:

• ‘binary’ if the connection was done via the binary protocol, for example to a target made with box.cfg{listen=…};
• ‘console’ if the connection was done via the administrative console, for example to a target made with console.listen;
• ‘repl’ if the connection was done directly, for example when using Tarantool as a client;
• ‘applier’ if the action is due to replication, regardless of how the connection was done;
• ‘background’ if the action is in a background fiber, regardless of whether the Tarantool server was started in the background.

box.session.type() is useful for an on_replace() trigger on a replica – the value will be ‘applier’ if and only if the trigger was activated because of a request that was done on the master.
