I discussed this in many of my videos, the need for a database that natively supports a multiplexing protocol such as QUIC, gRPC or HTTP/2 in order to allow multiple isolated clients to make requests to the database without taking the overhead of establishing multiple connections.    Resources https://www.infoq.com/news/2021/01/eventstoredb/ https://developers.eventstore.com/clients/dotnet/5.0/streams/#writing-to-a-stream

Let us discuss what I'm excited for in Backend Tech in 2021 and answer your great questions

In this video, I go through my process of how I design and architect full software from A-Z. This is part of a Twitter thread that you guys seem to enjoy so I decided to make a video on the topic. Although the spec I generate is usually Backend oriented this is applicable for all software.  Twitter thread https://twitter.com/hnasr/status/1339021983195918337?s=20
