throttling

问题 I'm trying to implement some throttles on our REST API. A typical approach is after a certain threshold to block the request (with 403 or 429 response). However, I've seen one api that adds a delay to the response instead. As you make calls to the API, we will be looking at your average calls per second (c/s) over the previous five-minute period. Here's what will happen: over 3c/s and we add a 2 second delay over 5c/s and we add a 4 second delay over 7c/s and we add a 5 second delay From the

问题 I need to implement ratelimiter/throttling in one of my microservice. For example I have one User microservice that handles login and get user data based on role like Admin or normal user that is implemented using JWT token and annotation @Secured, So, My ask is to throttle based on these what api is being called.And, I should be able to modify the throttle limit at runtime too. I don't want to re-invent the wheel, so, any ideas please? technology stack:- java, spring boot 回答1: Answer to this

问题 I think RxJS should perfectly fit to supress dublicate button clicks for 2 seconds. However, Im struggleing with the implementation. var $button = $('#myButton').button(); $button .toObservable("click") //.Throttle(2000) // Wouldn't fire the first event instantly :-( .Subscribe(function(){ alert('clicked'); }); I already created a jsFiddle for your convenience. You need to scroll down in this fiddle, because I just pasted Rx inside as I couldn't find a CDN. http://jsfiddle.net/cburgdorf/mUMFA

问题 I am trying to throttle a loop (which is sending messages) to a particular number of messages per second. _throttle is the number of messages per second. My initial algorithm is depicted below, but the delays are not smooth. What improvements can I make to smooth out the rather bumpy delays and bursts of messages. I have played around with the tick, and the interval max, but the inbound count is so large it's hard to compensate. The maximum rate I can achieve with the throttle off in my

问题 Our organisation is currently migrating to Apigee. I currently have a problem very similar to this one, but due to the fact that I am a StackOverflow newbie and have low reputation I couldn't comment on it: Apigee - SpikeArrest behavior If there is any way to merge the two questions please let me know. So, in our organisation we have 6 MessageProcessors (MP) and I assume they are working in a strictly round robin manner. Please see this config (It is applied to the TARGET ENDPOINT of the

问题 I would like to run a bunch of async tasks, with a limit on how many tasks may be pending completion at any given time. Say you have 1000 URLs, and you only want to have 50 requests open at a time; but as soon as one request completes, you open up a connection to the next URL in the list. That way, there are always exactly 50 connections open at a time, until the URL list is exhausted. I also want to utilize a given number of threads if possible. I came up with an extension method,

问题 I have a ASP.Net web site that get all business logic from a WCF hosting site (IIS). Once in a while, it looks like the backend WCF frozen and that makes web front-end stop responding. I have to recycle both application pools to make it work again. It happens more often lately, could be because we have more & more customers using the site. Before, it happens once every month, now it happens once every week. Maybe more. We DO Close connection after each SVC call. Error message received in

问题 I'd like to restrict the number of calls to a particular method on my WCF service, by any distinct IP, to x calls per timeframe y . So for example, if IP 10.0.1.1 calls the method register more than 5 times in a particular minute (call it minute x ), when it it tries to call that method a sixth time in that minute it is blocked until minute ( x + 1 ). This is because the only non-token authorized call on my system is the register call. I am worried that attempts to flood this method with

问题 I want to use a JS Throttle. But i'm struggeling to get it work correctly. I tried the code from this article: https://codeburst.io/throttling-and-debouncing-in-javascript-b01cad5c8edf But the Throttle does not work as intended, since everytime i click on the button, one "|" is added to the div. No clicks were discarded. where is the misstake? function foo() { $("#respond").append("|"); } const throttle = (func, limit) => { let inThrottle return function() { const args = arguments const

问题 I am wondering whether on Windows Server 2003, in Windows Media Service, we could setup/configure throttling settings for any file types (even the file types not supported by streaming by Windows Media Service), for example, setup .flv file download/streaming throttling bit rate to 100k or setup the bitrate throttling control to the same as encoded bit rate. I have searched Windows Media Service manual for a long time, but can not find this feature exlpicitly documented. BTW: I am just
