Dawid Weiss commented on LUCENE-10574:
--------------------------------------
I like [~jpountz]'s solution... even if it's not perfect!
Merge strategies would indeed benefit from some algorithmic love - the problem
in my experience is that no single strategy fits all types of loads. In reality
the merge strategy, the merge scheduler and the balance between searches and
indexing all play a key role and finding the best performing solution is a
combination of all these factors.
