Check out my new course Learn you some Lambda best practice for great good! and learn the best practices for performance, cost, security, resilience, observability and scalability.
BERT (Binary ERlang Term) is a binary format based on Erlang’s binary serialization format (as used by erlang:term_to_binary/1) but supports a couple of complex types such as boolean, dictionary and time, in additional to the primitive types.
BERT and BERT-RPC was specified by GitHub’s cofound Tom Preston-Werner and bas been in production use at GitHub as part of their infrastructure allowing them to integrate Ruby and Erlang through the Ernie BERT-RPC server.
The encoding format for BERT is the same as Erlang’s external term format which you can read about in great detail here. It is not as highly optimized as something like protocol buffer but is very easy to understand and implement and does not require a separate contract definition file (the .proto file for protocol buffer) in order to be able to serialize a type.
How can I try it?
I have yet to put together a Nuget package for Filbert but will do so in the near future, in the mean time why not fork the project on GitHub and try it out for yourself?
I have ensured reasonable test coverage for both encoder and decoder but there are no doubt many edge cases which I haven’t considered and would really appreciate any feedback you have on how best I can improve the solution
I specialise in rapidly transitioning teams to serverless and building production-ready services on AWS.
Are you struggling with serverless or need guidance on best practices? Do you want someone to review your architecture and help you avoid costly mistakes down the line? Whatever the case, I’m here to help.
Check out my new podcast Real-World Serverless where I talk with engineers who are building amazing things with serverless technologies and discuss the real-world use cases and challenges they face. If you’re interested in what people are actually doing with serverless and what it’s really like to be working with serverless day-to-day, then this is the podcast for you.
