I'm using PowerShell 7.4 LTS and I have experience with large-scale automations, so I'm not a beginner. I'm specifically looking for good learning resources for the ForEach-Parallel command. I want to dive into its capabilities without relying on workarounds like Start-Job. Also, I've been sending error results to ChatGPT, but it seems to be hallucinating a lot. Additionally, I'm avoiding older data structures like Hashtable and ArrayList because they're slow and not thread-safe; I'm focusing on using [System.Collections.Generic.Dictionary] instead. If you have any recommendations for books or other resources, I'd greatly appreciate it!

It looks like you're on the right track, but it’s odd that nothing outputs in parallel mode. You mentioned that it works without -Parallel though, which is a good sign. Double-check if paths or file writing conflicts might be causing this issue! You can find more insights here: [additional resource link]
It sounds like you’re facing some challenges with ForEach-Parallel. Have you thought about sharing your specific issues or code snippets? A lot of times, it helps to debug together instead of guessing in the dark. Sharing your script can really clarify the problem we're trying to tackle!
Sure thing! Here’s a link to my code: https://pastebin.com/y4K518QN
If you're struggling, check out the official documentation for ForEach-Parallel. It can be pretty informative! Also, what exactly are you trying to achieve with it? Getting familiar with nested hashtables while querying the event logs can definitely be tricky. Make sure you’re clear on how parameters work in the scriptblock too.
I am trying to iterate over a nested hashtable with queries for Windows Event logs and collecting selected properties into a thread-safe collection, then export this to JSON. I’ve read the docs, but they don’t clarify the use of parameters inside the scriptblock.
I’ll look into that! This is quite frustrating because everything seems fine until I add -Parallel.
