Re: [External] Maximum SSTable size

[Tom van der Woerdt <to...@booking.com>]

I’ve had SSTables as big as 11TB. It works, read performance is fine. But,
compaction is hell, because you’ll need twice that in disk space and it
will take many hours 🙂

Avoid large SSTables unless you really know what you’re doing. LCS is a
great default for almost every workload, especially if your cluster has a
single large table. STCS is the actual Cassandra default but it often
causes more trouble than it solves, because of large SSTables 🙂

Hope that helps!

Tom
