I have the same question on this.
I’m using Cockroach DB v1.0.6 on Windows10 with binary version. And have 3 nodes running on one computer.
I’ve been running the nodes for about 2 days.
Live bytes of each node are 1.1GiB in Admin UI, and data directory size of each node from the filesystem is about 100MiB but not same like 99, 111, 122MiB. I dumped my database to know approximate data size of what I store without thinking of replicas and time series data. And its size is 332KiB.
And also, my current value of ‘Replicas per Node’ is 33. each maximum chunk size is default 64MiB, so current maximum size with same ‘Replicas per Node’ value is 2112 MiB per Node. In this case, the average chunk size is about 33MiB(1.1GiB / 33 replicas per node) currently? And default replicas per range is 3, so it has about 11 ranges now.
I assume that current size of each Node is 1.1GiB, and it compressed to about 100MiB. Am I correct even a quite big difference? I think I didn’t get the point much. Can you explain about this a bit more?
