kandi X-RAY | opossum Summary
Opossum is a Node.js circuit breaker that executes asynchronous functions and monitors their execution status. When things start failing, opossum plays dead and fails fast. If you want, you can provide a fallback function to be executed when in the failure state. For more about the circuit breaker pattern, there are lots of resources on the web - search it! Fowler's blog post is one place to start reading.

QUESTION
How do I find a list of substrings in a dataframe against an array and use the array values to create a new column? For example, I started off using str.contains
and typing out the actual string value(see below).
ANSWER
Answered 2021-Oct-05 at 01:01I think there's a cleaner way to write this, but it does what you want. If you are worried about case-sensitive, or full word matching, you'll have to modify this to your needs. Also, you don't need a np.array, just a list.
QUESTION
How would I go about ignoring the case sensitivity in this code below? I have a list that's looking up a substring of a dataframe but I'm finding that it's case sensitive.

QUESTION
We are using the Jenkins docker plugin to pull the CI image from docker.com. This has worked for years:
...ANSWER
Answered 2021-Apr-14 at 06:59If you are not logged in to docker.com, "you" as used in the error message seems to be identified by the IP address. In a setup where multiple systems pull from docker.com with the same IP address (e.g., a university), you will quickly run out of resources. As a result, things may suddenly look broken just because someone else on the network depleted the resources.
By using a free Docker account, your CI server will be assigned its own resources.
Steps:
- Create an account on hub.docker.com.
- Add the credentials to Jenkins' credential store. In this example, the credentials have the ID
docker
. - Modify your Jenkinsfile to use the account:
QUESTION
I'm trying to figure out what is the best wait to implement a circuit breaker based of the number of requests been served in a Typescript/express application instead of fails percentage.
Since the application is meant to be executed by large number of users and under a heavy load, I'm trying to customize the response code in order to trigger a horizontal scaling event with k8s/istio.
The first thing I want to start with is to get is the number of requests in nodejs eventloop event if there is some async work in progress, because a big part of my request are executed asynchronously using async/await.
BTW:
I have seen these Libs
Is there any good Idea/path I can start with in order to make this possible ?
...ANSWER
Answered 2021-Jan-04 at 00:24I can't tell for sure from your question, but if what you're trying to do is to just keep track of how many requests are in progress and then do something in particular if that number exceeds a particular value, then you can use this middleware:
