Yes... your insanely over-huge commitlog will be contained in fewer files
if you increase the size of segments.... that will not make it any less of
an insanely over-huge commitlog which indicates systemic failure in your
application's use of Cassandra. Congratulations on masking your actual
issue with your configuration change.

1/4 attempts to flush blocked waiting for resources, and you have 6 actives
flushes and 10 pending, because YOU'RE WRITING TOO FAST.

As a meta aside, I am unlikely to respond to further questions of yours
which do not engage with what I have now told you three or four times, that
YOU'RE WRITING TOO FAST.
