Describe the bug

I run some data(300g) in small mem(64g) with sort merge join spill.
Then i get error
Failed to allocate additional {} for {} with {} already allocated for this reservation - {} remain available for the total pool

And i try to fix it. I fix two code
remove this code:

self.reservation.try_resize(self.converter.size())?;

and

match self.reservation.try_grow(size) {

to

loop {
match self.reservation.try_grow(size) {
Ok(_) => Ok(()),
Err(e) => {
if self.in_mem_batches.is_empty() {
return Err(Self::err_with_oom_context(e));
}

            // Spill and try again.
            self.sort_and_spill_in_mem_batches().await?;
    }

}

I think the issues are as follows:

  1. The memory was immediately occupied as soon as the sort operator spilled data to disk.
  2. The row operator failed to spill data to disk, which caused this problem.
    So could we fix it in this way, or are there any better solutions?
