This question is more rather more about an option on how to scale certain services in Kubernetes. I think the best pattern for this is to have a Kubernetes Operator. Essentially, this would manage the lifecycle of your nsqd application. There are several operator tools that you can use to create your nsqd operator:

• Operator Framework
• KUDO
• Kubebuilder
• Metacontroller

A good example of a scale-out operator is Srimzi which is Kafka operator for Kubernetes.

You can also find other well-known operators in the Operator Hub.

You can use use to pass variables to a function callback like this:

I come across this problem often in webscraping. The key is to store the intermediate results in an environment where they are accessible if your function throws an error. The obvious place is the global environment, but this depends on how you are using your function. If it is part of a package, then you don't want to write to the global workspace. In that case you can have a "storage" environment as part of the package.

Perhaps the neatest way to do this is to delete the intermediate object after the loop is complete, so it will only ever be visible / accessible if the loop throws an error.

Here is a function that demonstrates the principle:

The issue here is most certainly the fact that You never call the open() method of the superclass. This will cause some of the variables to be uninitialized. This should be solved by calling the super.open() inside Your open() method.

TLDR;

Just look up the symbol (ie. AAPL or GOOGL). The IXIC is an index, Alpha Vantage currently does not cover indexes.

Further notes:

1. Quotes from Alpha Vantage are aggregated, so any price you're getting won't be the price from what it's traded on the NASDAQ, but a quote of what the price is across exchanges.

2. If you're looking for a specific symbol, you can check for what it's listed as using the search endpoint.
