Is Erlang garbage collected?
Currently Erlang uses a Generational garbage collection that runs inside each Erlang process private heap independently, and also a Reference Counting garbage collection occurs for global shared heap.
Does elixir have garbage collection?
Since Elixir uses garbage collection (“GC”), it checks that box. But here’s the thing: what all GC languages do for memory safety, Elixir also does for safe concurrency.
Why is garbage collection so important in Elixir?
When garbage collection is needed. If there isn’t enough space in memory to put new information, garbage collection is launched. It removes data that’s no longer necessary for the app to work, and then the app resumes. Erlang uses GC that separate objects in the heap into two categories: long-term and short-term.
How does Erlang handle generational garbage collection?
In addition to the collection algorithm described above, the Erlang garbage collector also provides generational garbage collection. An additional heap, called the old heap, is used where the long lived data is stored. The original heap is called the young heap, or sometimes the allocation heap.
What is Erlang and beam?
It is time to change that! Erlang and the BEAM VM were invented to be the right tool to solve a specific problem. They were developed by Ericsson to help implement telecom infrastructure handling both mobile and fixed networks. This infrastructure is highly concurrent and scalable in nature.
What is heap fragments in Erlang?
Heap fragments are extra memory blocks that are a part of the young heap, but are not allocated in the contigious area where terms normally reside. See The young heap for more details. Erlang has a copying semi-space garbage collector.
How does ererlang garbage collection work?
Erlang has a copying semi-space garbage collector. This means that when doing a garbage collection, the terms are copied from one distinct area, called the from space, to a new clean area, called the to space. The collector starts by scanning the root-set (stack, registers, etc).
