Create an array of executor services running one thread each and assign your queue entries to them by the hash code of your item id. The array can be of any size, depending on how many threads at most do you want to use.

This will restrict that we can use from the executor service but still allows to use its capability to shut down the only thread when no longer needed (with allowCoreThreadTimeOut(true)) and restart it as required. Also, all queuing stuff will work without rewriting it.
