Because they are friends with CEO/board/investors. I interviewed three startups that are exactly like that. One of the CTO asked how I would validate US zip code. I told him there are around 42K zip code, just store them in a hashmap and do lookups. He thought I was crazy and insist on Trie tree.
- gravypod 5y agoI've spoken to some who say they need real time stream processing off of MQTT backed by a Spark cluster..... To store ~10 messages/second. I've reduced infra costs and improved perf by just turning it into an API with a retry on the client and storing into a database. After I left, I hear he's rebuilding the Apache Spark data pipeline stuff "so we can scale". (This problem they were solving was embarrassingly parallel and could have been shared like crazy to make it way cheaper to host)
