I’ve been playing with #ProjectValhalla and the new #Java Value Classes (JEP 401), and I thought:
“What happens if Protobuf messages become value classes?” 🤔
So I wrote a small protoc plugin and ran a few experiments:

I wrote this blog post to share some hacking sessions with the new #Java #Virtual #Threads.
While these are new and cool tools, they can hide new pitfalls to solve.. see the details in the post!

A memory model addresses challenges arising from cpu caches and the need for processors to see consistent values. And also compilers and processors may reorder instructions for optimization, making a memory model necessary to handle these cases! 🤯

synchronization mechanisms ensures that memory writes by a thread are made visible to other threads in a predictable manner. 🔎
In #java we have a memory model that define the conditions under which writes to memory by one processor become visible to other processors. ☕️
Usually when we think about synchronization mechanisms between threads we focus on mutual exclusion. 🔒
An important aspect is also memory visibility...🧵
