Spring Boot WebClient stops sending requests

Asked 2022-Feb-18 at 14:42

I am running a Spring Boot app that uses WebClient for both non-blocking and blocking HTTP requests. After the app has run for some time, all outgoing HTTP requests seem to get stuck.

WebClient is used to send requests to multiple hosts, but as an example, here is how it is initialized and used to send requests to Telegram:

I would propose to take a look in the RateLimiter direction. Maybe it does not work as expected, depending on the number of requests your application does over time. From the Javadoc for Ratelimiter: "It is important to note that the number of permits requested never affects the throttling of the request itself ... but it affects the throttling of the next request. I.e., if an expensive task arrives at an idle RateLimiter, it will be granted immediately, but it is the next request that will experience extra throttling, thus paying for the cost of the expensive task." Also helpful might be this discussion: github or github

I could imaginge there is some throttling adding up or other effect in the RateLimiter, i would try to play around with it and make sure this thing really works the way you want. Alternatively, consider using Spring @Scheduled to read from your queue. You might want to spice it up using embedded JMS for further goodies (message persistence etc).

Upgrading to Symfony 6 from 5.3

ANSWER

Answered 2022-Feb-10 at 21:35

That composer.json file is a bit of a mess. Some Symfony packages on 5.3, some even on 5.1, and many on 6.

Also you are controlling Symfony versioning from extra.symfony.require, and at the same time from the discrete version constraints. You include some packages that no longer exist on 6.0 (symfony/security-guard), and are missing some that should be installed on a 6.0 version.

It's simply not on an installable state.

I've managed to make it installable changing it like this:

QUESTION

What is the purpose of renaming this key in a redis sliding window rate limiter implementation?

Asked 2021-Nov-08 at 00:41

I'm looking at the source for the redis-rate-limiter library here on line 11.

Going through the exec, using "10/minute" rate/duration:

Create temp key prefixed with ratelimittemp:ID to 0 and set to expire in 60 seconds
Rename to ratelimit:ID
Increment ratelimit:ID
Get TTL

What's the point of a rename here?

...

ANSWER

Answered 2021-Nov-08 at 00:41

It's a way to refresh the rate limiter counter. It renames the temp key to real key if the real key does not exist, i.e. renamenx.

If the real key exists, increase the current counter, and see if we reach the rate limit of current time window. However, if the real key does not exist, it means the the previous time window, e.g. 1 minute, has been passed, and we need to start a new time window, i.e. a new counter. So we rename the temp key (with time window as expiration) to the real key, and increase on this new real key.

Why do I get this error when I attempt to upgrade Symfony by changing `extra.symfony.require`?

Asked 2021-Sep-24 at 11:12

ANSWER

Answered 2021-Sep-24 at 11:01

You have conflicting requirements.

On extra.symfony.require you say you want 5.3.*.

But on your individual Symfony requirements you are specifying either ^5.2 or 5.2.* (and in some cases ^5.3 as well).

When a project uses Symfony Flex (as is your case), the presence of extra.symfony.require will be used to restrict what package versions to install for many/most Symfony packages. But only if you do not declare a specific version on your require section.

In this case, you are already specifying a version on the 5.* range on extra.symfony.require. Leave that one like that, and just use * as a version constraint for all the other Symfony Packages in the require section.

(Note that's it's not really all, since some packages are not managed by Flex, just update the ones that have versions declares in the 5.* range)

it's the vizier of dynamic memory allocation reporting in again.
