Distribution topology from @distribute directive.

Bare @distribute with no args inherits cluster defaults.

Fields

sharding: Option<String>

Sharding strategy: “hash”, “range”, or custom (default: none)

Explicit shard count override. When Some(n), n >= 2. When absent, the cluster default applies.

residency: Option<String>

Residency mode: “sharded”, “full”, “mirrored”, “adaptive” (default: “full”)

replication_factor: Option<u8>

Number of replicas: 1-255 (default: cluster default)

consistency: Option<ConsistencyMode>

Consistency mode: strong or eventual (default: eventual)

replication: Option<String>

Replication control: “false” to disable, “global” for all regions
