Multi-threading and Multi-processing Architecture Questions for Nautilus Trader

[trylovetom]

I have two questions about running multiple actors and strategies with proper multi-threading/multi-processing in Nautilus Trader:

Question 1: Multi-threading with Actors for Streaming Data

I have 10,000 instruments and want to use the streaming feature to write data to files. My plan was to create 1 live node with 10 actors, where each actor subscribes to 1,000 instruments.

However, I found that all 10 actors have the same process ID, thread ID, and thread name - meaning they run on a single thread. I expected them to run on 10 separate threads orprocesses.

How can I achieve multi-threading or multi-processing with multiple actors? What is the recommended approach?

Question 2: Running Multiple Strategies with Separate Processes

According to the documentation (https://nautilustrader.io/docs/latest/concepts/architecture/#processes-and-threads), I need to separate my 2+ strategies into different processes.

I tried both approaches:

• 1 live node with 2 strategies
• 2 live nodes with 1 strategy each

But all strategies still have the same process ID, thread ID, and thread name.

How can I deploy 2+ strategies using the same data client and execution client, but running in separate processes? What is the standard approach?

You can open two startup scripts

Thank you for your reply. If you are answering question 2, I cannot split it into two startups because my data client and execution client have connection limits. So, I need to share them.
