> Stopping node during checkpoint leads to binary memory recovery after node start.
> When binary memory is restored node performs checkpoint that fixes the consistent state of the page memory.
> It happens there

> {noformat}
> Looking at the implementation of this method we can notice that it performs finalization in 1 thread, which is not optimal. This process can be speed-up using parallelization of collecting checkpoint pages like in regular checkpoints.
