As we defined, front pressure is algo that cannot slow down or we may say cannot control the asynchronous flow, it just simply choose the destination and send
besides, back pressure algorithms can
Therefore most popular strategies are both front-pressureFront pressure can be used safely with sync requests or blocking actions, this helps client lock the resource that are calling at server and then slow down the process speed of the client
But locking is not an efficiency action, it will lock more than just the resources it needs.
So we need a backpressure strategy with some constraints to design algorithms
