Retain.concurrency: 1

I want to configure the retain.concurrency:1 parameter to reduce disk load during garbage collection. What negative consequences can this have?

Non. I am running it like this all the time. My question is more the other way around. Why don’t we make 1 concurrent retain the new default?


what does this command do and why do you need it?

What is the default if this parameter is not set?

storagenode run --help will print out all default values
