QUESTION
my project uses AWS Chalice framework and sqlalchemy.
Here is a sample table from the project.
I am required to get data from table in two formats. I require two separate queries which should give the data in different format as both will have separate apis. Please do not combine the query to give data in both formats together as dataset is huge & there will be performance issues and as already mentioned I need them separately.
First Format:
I want to get count of person for different jobs grouped by city and if the job field is empty/none, then it should be treated as No Job.

I have a very simple chalice app with a scheduler that I want to deploy to aws lambda. Everything worked fine, however suddenly I cannot deploy the chalice app anymore. It hangs on the line Creating lambda function: test-dev-periodic_task for a very long time and then I get the following error message.
ANSWER
Answered 2021-Nov-21 at 18:14I just solved it. Apparently my network connection wasn't great. I sat closer to the wifi access point and suddenly it worked. Notice: My internet connection was working the whole time, so it seems chalice deploy is a little bit finicky with network issues.

I have tried to install requirements.txt using pip install -r requirements.txt. I always get this error:
ANSWER
Answered 2021-Nov-11 at 10:59For the missing script due to installation, use this: python -m ensurepip --default-pip For more, you can check this
You can also check this issue on GitHub here
ensurepip is a package that supports bootstrapping for pip. It is used when for some reason installing pip was skipped. From the doc:
In most cases, end users of Python shouldn’t need to invoke this module directly (as pip should be bootstrapped by default), but it may be needed if installing pip was skipped when installing Python (or when creating a virtual environment) or after explicitly uninstalling pip.

Answered 2021-Nov-05 at 09:05- Good news, it looks like you are reaching your lambda.
- Check aws cloudwatch logs: /aws/lambda/helloworld-{dev|prod}
- If can't solve it, upload .chalice/config.json and the error of the logs in clouwatch

QUESTION
I am building an application backed by a Neptune database. Because I want the application to be scalable, I am using AWS Lambda + API gateway to build a REST API to interact with the database. This seems to be a reasonable idea based on the fact that this use case is documented in the Neptune docs.
The Neptune docs recommend reusing the websocket connection to the database across the entire execution context of the function, which is what I am doing at the moment. The docs also recommend resetting the connection and retrying upon errors (see here), which I am also using. However, I am seeing exceptions every now and then (perhaps every 20 requests on average). One of the exceptions I get is
ConnectionResetError: Cannot write to closing transport
which seems to be the same as this issue.
The other one is:
...ANSWER
Answered 2021-Nov-03 at 13:23The latest version of Neptune only supports Gremlin 3.4.11 (https://docs.aws.amazon.com/neptune/latest/userguide/engine-releases-1.0.5.1.html). I would start by using gremlin-python 3.4.11 and see if that resolves your issue. Gremlin-python 3.5 replaced Tornado with AIO HTTP (ref) for websocket connections and I suspect that change may be causing a slight change in behavior that a future release supporting Gremlin 3.5 will address.

Install chalice
You can use chalice like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
