Best practices/examples of hardening an actor that handles tens of thousands of records?

I was told to post this here instead of #chat by DanielDo:

I'm looking for any helpful links/articles/source code for writing actors that split a collection of objects from a dataset into paged collections for batching? I want to support actor input for capping the total dataset records that are allowed to be processed, the size of each page/batch, etc.

The objects retrieved will have a url in one of their keys that the actor will then go fetch and save to the local fs, so I'd like to make sure the actor can stop and resume where it left off without redundant fetches or fs operations.

The end goal is to go from having a dataset with records in the shape of { image: 'https://..../x.png', identifier: 'My Image' } to a zipped archive of all of the images–and the images will be nested under parent directories that are named based on the identifier key of a given record.

Accessing actor dataset locally in a monorepo

I haven't been able to find any information on how accessing datasets via client works for local development–does this only work on the platform? I have a monorepo with two actors and I'd like to access a named dataset from one actor inside the other. If accessing the datasets of other actors is not possible via openDataSet locally, what alternatives are there?

Example monorepo repository + CLI for deployments

The example monorepo (seen here: https://github.com/apify/actor-monorepo-example) doesn't cover how apify push is intended to be used – the only place you're able to use it is from the root of the repository, but doing it there shows the following in console:

Plain Text
apify push
Info: Created actor with name undefined on Apify.
Info: Deploying actor 'undefined' to Apify.
Run: Updated version 0.0 for my-actor-5 actor.
Run: Building actor my-actor-5

Using env vars with secret values via `apify secrets:add`, `actor.json`, and default start script

The documentation (https://docs.apify.com/cli/docs/vars) doesn't touch on how you access any environment variables set in actor.json in an actor's source–I'm using the monorepo example repository.

I'm using lukaskrivka/images-download-upload to grab all image urls from a dataset from one of my actors. You can see above that it's retrieving the urls successfully and appears to process/download them but the resulting zip file is empty every time. Anyone have any insight or suggestions for alternatives that work?

One-off charge or lower price for ability to use proxies locally?

$49/m is too steep for me at this point in time–I'm just exploring the platform and am hoping that it's possible to pay a handful of schrute bucks so I can run my actor locally on my own machine.
