Well, THERE'S your problem! If you are doing http/json between microservices then you are definitely holding it wrong. Do yourself a favor and use protobuf/grpc. It exists specifically for this purpose, specifically because what you're doing is bad for your own health. Or Avro, or Thrift, or whatever. Same thing. Since Google took forever to open source grpc, every time their engineers left to modernize some other tech company, Facebook or Twitter or whatever, they'd reimplement proto/stubby at their new gig. Because it's literally the only way to solve this problem. So use whatever incarnation you like.. you have options. But json/http isn't one of them. The problem goes way deeper than serialization efficiency. (edit: d'oh! Replied to the wrong comment. Aw well, the advice is still sound.)
