WAIT FOR EVENT

Description

Waits for event Confirmation.

Slonik remembers the last event generated on every node during script execution (events generated by earlier calls are currently not checked). In certain situations it is necessary that events generated on one node (such as CREATE SET) are processed on another node before issuing more commands (for instance, SUBSCRIBE SET). WAIT FOR EVENT may be used to cause the slonik script to wait until the subscriber node is ready for the next action.

WAIT FOR EVENT must be called outside of any try block in order to work, since new confirm messages don't become visible within a transaction.

Example

WAIT FOR EVENT (
  ORIGIN = ALL,
  CONFIRMED = ALL,
  WAIT ON = 1
);
