kv,server: enable some degree of range descriptor pre-fetching in secondary tenants #91433
Description
Is your feature request related to a problem? Please describe.
Currently we do not pre-fetch any additional range descriptors. See
cockroach/pkg/ccl/kvccl/kvtenantccl/connector.go
Lines 397 to 400 in 4488445
Describe the solution you'd like
We should add some logic to filter range descriptors returned based on the tenant and then use the same pre-fetching logic we use in regular KV.
