Will there be a function in proxmox, analogous to the function in esxi VMware vSphere Fault Tolerance

I would like to know if a similar feature like esxi is planned in the future.

Two machines must run in parallel yes two servers and always synchronized

VMware vSphere Fault Tolerance (FT). This feature provides continuous availability of virtual machines (VMs) by creating a full copy of a running VM on another ESXi host.

QEMU provides such functionality under the name COLO (for "COarse-grained LOck-stepping") [1]. But last time we looked at it, it wasn't quite ready for prime time to my knowledge.
