Who was responsible for the maintenance and support of the distributed data storage system?

The memory for a goroutine in Go is allocated from a stack managed by the Go runtime. Unlike traditional threads, goroutines start with a very small stack (usually a few kilobytes), which can dynamically grow and shrink as needed.

When a new goroutine is created, the runtime allocates a small stack in the heap for it, and then increases its size if necessary. This allows thousands or even millions of goroutines to run with minimal memory consumption.

Thus, the memory for a goroutine is allocated from a managed memory area by the runtime, not directly from the system stack.
