Memory pool is a memory management technique that pre-allocates a large amount of memory from the system and then provides it to the client when needed. It is also known as fixed-size block allocator or region-based memory allocator. It is a special case of object pool pattern. It is used to manage memory in garbage collected languages where the garbage collector does not provide efficient memory management.
- Safe Memory Pool: Here we are using Go primitives like
make([]byte, size)andsync.Poolto allocate and deallocate memory. - Unsafe Memory Pool: Here we are using
unsafepackage to allocate and deallocate memory.
