weavelet and envelope

[陆西星]

How to understand the concepts of weavelet and envelope in the Google Weaver framework? They seem to be very important in the entire design. Could you share some insights?

[Srdjan Petrovic]

Yes, they are important. We're working on a blog post describing these in detail, but got side-tracked with some last minute API changes. We hope to release the post next week.

We just released a blog post detailing envelopes and weavelets: https://serviceweaver.dev/blog/deployers.html. By the end of the blog post, you'll be an expert :)

Hi @mwhittaker, Can you share why use os pipes instead other protocol for communication between envelope and weavelet?
Thanks!

[Srdjan Petrovic]

The weavelet is a child process of the envelope, and the pipe between them is protected by the OS against unauthorized access by other processes. So it is a safer communication medium than network-based protocols, which would have to be secured using mTLS.
