Re: [Discuss] num_tokens default in Cassandra 4.0

2020-01-30 Thread Jon Haddad
Yes, I'm against it. We should be using the default value that benefits the most people, rather than an arbitrary compromise. Most clusters don't shrink, they stay the same size or grow. I'd say 90% or more fall in this category. Let's do the right thing by default and include good comments that

I think lowering the number of tokens is a great idea! Similar to Jon, when I have reduced the number of tokens for clients it has been improvement in repair performance. I am concerned that the proposed default value for num_tokens is too low. If you set up a cluster using the proposed defaults,

Larger clusters is where high token counts do the most damage. That's why it's such a problem. You start out with a small cluster using 256, as you grow into the hundreds it becomes more and more unstable. On Thu, Jan 30, 2020, 8:19 AM onmstester onmstester wrote: > Shouldn't we consider the cl

Re: [Discuss] num_tokens default in Cassandra 4.0

Shouldn't we consider the cluster size to configure num_tokens?  For example is it OK to use num_tokens=4 for a cluster of more than 100 of nodes? Another question that is not so much relevant to this : When we use the token assignment algorithm (the new/non-random one) for a specific keyspa
