In many programs, you might have to wait for a particular condition to occur before you can perform a certain task. In some cases, you might use a WHILE loop to check whether the condition has occurred. With solidDB you can use events, which in some cases allow you to avoid wasting CPU time in a loop waiting for a condition to occur.

One (or more) clients or threads can wait on an event, and another client or thread can post that event. For example, several threads might wait for a sensor to get a new piece of data. Another thread (working with that sensor) can post an event indicating that the data is available. For more information about events, see Events.
