Is it bad to have threads waiting in java?
java, multithreading
Solution
No it is not bad to have waiting threads in general, it is common practice and often the nicest solution.
As the answer is pretty short, just a quick advice: If it is not necessary that your thread reacts immediately, you might consider adding `Thread.yield` to your infinite waiting loop, depending on the system it is running on this can save some unnecessary CPU-usage. See the Oracle documentation
Problem
I have a thread that basically contains ``` while(true) { current = BlockingQueue.take(); results = queryDatabaseWith(current); AtomicReference.set( results ); } ``` Realistically the queue is only ever going to have a few things put on it, but it's important that when things are, the DB queries happen in the correct order. The atomic ref is fine as I only care about the results from the last DB query. Is it bad practice to have this on a thread, basically waiting all day?
