Hello:

In a MDS environment, can we specify which data nodes to use per bucket?

Say, In a MDS environment there are two buckets with 4 data nodes.
D1
D2
D3
D4

and Buckets (B1, B2)

Can we specify that B1 uses D1 and D2 while B2 uses D3 and D4?

Not currently - Buckets are always distributed across all data nodes.
