Hi, I didn't discuss the DB because I wrote about it earlier (https://medium.com/prooftrading/selecting-a-database-for-an-algorithmic-trading-system-2d25f9648d02 …). We use SingleStore (fka MemSQL). The DB is not in the critical path of processing, but the performance definitely matters to us. I talk about why no kdb in that post (cost, learning curve).
You're welcome! Some of that info is a bit outdated - I'll do an update one of these days.
Great article, @preraksanghvi ! Can you talk about the technology used to distribute messages from sequencer to the rest of the apps in the cloud? looks like you used tcp solution for this?
