Concurrency Comparison: Go v/s Elixir

Posted on 30 Jan, 2023

Goroutines = CSP Process

• One goroutine only knows about channels, its not aware about other goroutines.

• There are anonymous

• Message passing is synchronous.

• Go routines are managed by Go runtime.

• Avg size in order on 2KB.

Example

go someFunction()

Elixir Process = Actor Model

• Processes communicate directly to each other

• Elixir process has an id (non-anonymous).

• Managed by BEAM Virtual Machine.

• Separate stack & heap.

• Average size of 0.5KB.

Example

spawn(fn -> ... end)
