HI all
I can't find any information about how cassandra handles reads involving
multiple sstables. Are sstables read concurrently or sequentially? Is read
latency directly connected to the number of opened sstables?
Regards
Grzegorz
Sequentially, and yes - for some definition of "directly" - but not just
because it's sequential, but also because each sstable has cost in reading
(e.g. JVM garbage created when you open/seek that has to be collected after
the read)

So I was running on my *local*, and all of my attempts to add to the
denylist were failing because the denylist_consistency_level was set to
QUORUM:

Awesome! That's great to hear!
Pls feel free to let me know if you have any questions!

and yes, you need to set the consistency level to ONE in the cassandra.yaml
if it's running in your local machine
denylist_consistency_level: ONE
