  • Pretty much every smaller company I’ve interviewed with expects a scalable distributed micro services architecture during design rounds. Then proceeds to tell me about their monolith during other discussions.

    RDBMSs are actually pretty good, you don't need NoSQL right out of the gate.

    Using in memory databases as source of truths instead of just cache. It's against the norm but incredibly easy to setup and get going and gives that sweet low transactional latency your platform team is looking for.

      Wait till the traffic patterns shifts unexpectedly or cache goes down 😛

      Hah Iagree with cache going down thing that can and will burn you especially if you're batching writes for more than an hour but query pattern shifts will burn even the most carefully designed databases.
