box.ctl.promote()

Since version 2.6.2. Renamed in release 2.6.3.

Wait, then choose new replication leader.

For synchronous transactions it is possible that a new leader will be chosen but the transactions of the old leader have not been completed. Therefore to finalize the transaction, the function box.ctl.promote() should be called, as mentioned in the notes for leader election. The old name for this function is box.ctl.clear_synchro_queue().

The election state should change to leader.

Parameters: none

Returns

nil or function pointer
