❔ Naming Conventions N-Tier architecture, conflicts?
If thats an a-ok practice I'll keep it as is and write the namespaces explcity when needed. In regards to your structure, I don't feel comfortable enough to put all my trust on the namespace 😅 Thanks!

❔ MongoDB Update nested elements
Well just doing {Events:{$ne: []}} covers both 😅 Anyways the select query isn't the issue, its just when I run the update command with the set that it says - matchedCount:0

❔ MongoDB Update nested elements
Are you sure? Iv'e just tested - { "Events": { $exists: true } And it returns documents where Events is empty.

❔ MongoDB Update nested elements
Your query will return all the documents. As Events always exists (might be an empty array though). What I did was - Events:{$ne: []} Which basically search for all the documents where events not equal to an empty array. meaning it has nested elements

Updating my database using batches of lets say 1000 rows at a time from the file. It shouldn't be over 10mb, so I don't really have an issue (this is why initially I wanted to avoid saving to disk etc.)

@IcyPhoenix @kaleb Yep your ideas worked, understood kaleb explanation. Never worked with streams before, I'll do some reading on the subject, ty! This is what I did - 
            var data= await _client.GetByteArrayAsync(url + fileName);

            using (var fileStream = new MemoryStream(data))
            {
                fileStream.Seek(0, SeekOrigin.Begin);

                using (var gzStream = new GZipStream(fileStream, CompressionMode.Decompress))
                {
                    using (var outputStream = new MemoryStream())
                    {
                        gzStream.CopyTo(outputStream);
                        byte[] outputBytes = outputStream.ToArray();

                        var result = Encoding.ASCII.GetString(outputBytes);
                    }
                }
            }
            var data= await _client.GetByteArrayAsync(url + fileName);

            using (var fileStream = new MemoryStream(data))
            {
                fileStream.Seek(0, SeekOrigin.Begin);

                using (var gzStream = new GZipStream(fileStream, CompressionMode.Decompress))
                {
                    using (var outputStream = new MemoryStream())
                    {
                        gzStream.CopyTo(outputStream);
                        byte[] outputBytes = outputStream.ToArray();

                        var result = Encoding.ASCII.GetString(outputBytes);
                    }
                }
            }

Saying that an atomic operation is having a lock on the hardware level is a correct statement?

How to locally loadbalance threadsafe [Answered]
Ok so queue is out. I'm not sure what atomic operation actually is, not sure how it achieves that without a lock. I'll be googling for a few minutes and come back afterwards 😅

How to locally loadbalance threadsafe [Answered]
Ok so instead of reseting the indexCounter you modulo it with the length of the array. makes sense, not really worried about overflow each instance won't be surpassing the 1-2 million. Using Interlocked.Increment means that a lock is in place on every update so it makes the indexCounter incremental thread-safe, correct? It shouldn't affect performance as such a basic operation won't hold the lock? That being said, I can abandon the index counter and use concurrent queue to manage that for me if I dequeue and enqueue before awating the request? Something like - 
  ConcurrentQueue<string> _endpoints;
  public MyClass(List<string> endpoints)
  {
    _endpoints = new ConcurrentQueue<string>(endpoints);
  }
  
  public Task SendRequest()
  {
    var endpoint = _endpoints.Dequeue();
    _endpoints.Enqueue(endpoint);
    
    await client.Request(endpoint);
  }
  ConcurrentQueue<string> _endpoints;
  public MyClass(List<string> endpoints)
  {
    _endpoints = new ConcurrentQueue<string>(endpoints);
  }
  
  public Task SendRequest()
  {
    var endpoint = _endpoints.Dequeue();
    _endpoints.Enqueue(endpoint);
    
    await client.Request(endpoint);
  }
What do you think? @Xymanek

I'll start off by reading what each type is. As all 3 do not serve the same purpose at all. https://docs.microsoft.com/en-us/dotnet/csharp/language-reference/builtin-types/enum I'm sure that after reading the doc of each type you'll have a better understanding or a more specific question to follow up with.
