This is an experimental change to increase the default range size. It will only apply to new cluster. This range size is intentionally very large in order to stress the impact of the change. The hope is to validate the change at this size with an intention of shipping with something like 512MB/64MB. Release note (general change): New clusters will use an increased default range size of 2GB and will no longer be merged if larger than 128MB as opposed to the previous 16MB. This change will not affect pre-existing clusters. Range size settings are controlled through zone configs.
Before 19.2 we needed to disable the merge queue in order to issue splits. There's no good reason to disable it in later versions. Doing so may be masking problems Release note: None
