> Project: Ignite
> Issue Type: Improvement
> Reporter: Ivan Bessonov

> Priority: Major
> Labels: ignite-3
>
> We can enrich the GC thread with the ability to allocate segment files in
> advance. The number of files will be configurable.
> It's convenient to do that in GC thread because it monitors real log size and
> is always aware of the amount of free space.
> We should force GC thread to check for the necessity of pre-allocations every
> 50ms, for example. On idle thread it can be a simple "{{{}wait(50){}}}" in a
> loop, on not-idle thread we can periodically call the callback that would
> maybe pre-allocate new file.
