> In IGNITE-23550, it was discovered that fsyncs we do when writing each
> revision checksum (that is, on each Metastorage revision) are too costly.
> They were made durable to be durable to solve the 'durable side effects for a
> rolled-back Metastorage updated' described in IGNITE-23910, but the price of
> the current design is too high.
> In IGNITE-23910, we'll work in another solution to the same problem. For now
> the best thing we can do is just turn off the fsyncing as cases like
> IGNITE-23910 are extremely rare and we should not pay with everyday
> performance for them.
