Below some frequently asked questions about CoralStore.

1. When using an asynchronous store, don’t you lose messages in the queue in the event of a crash?
   No. CoralStore will automatically drain the queue using a shutdown hook in the event of a crash. You can also control the queue explicitly if you want to with the methods below, but you don’t have to.

   // this method will block, wait for the store queue to be drained and then return
   asyncStore.drainAndWait();
   
   // drain and close the the store gracefully
   // this method will NOT block, returning immediately, but all messages from the store will
   // be processed before the store is closed
   asyncStore.close(); // returns immediately, but adds a close event in the queue for this store
