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?

Hi All!
According to TWCS documentation (
https://cassandra.apache.org/doc/latest/cassandra/operating/compaction/twcs.html)
the operator should choose compaction window parameters to select a
compaction_window_unit and compaction_window_size pair that produces
approximately 20-30 windows.

Hi
I'm using tablestats to get estimated number of partitioning keys. In my
case all writes are done with TTL of a few days. Is the key count decreased
when TTL hits?

Hi all
I'm a bit confused with how read repair works in my case, which is:
- multiple DCs with RF 1 (NetworkTopologyStrategy)
- reads with consistency ONE
The article #1 says that read repair in fact runs RF reads for some percent
of the requests. Let's say I have read_repair_chance = 0.1. Does
Hi all
Does local write count provided by tablestats include writes from gossip?
