}

The decision.

Variants

PlaceAtHolder

Run on a node that already holds every shard; nothing moves.

Fields

node_id: String

The chosen node.

FetchThenPlace

Fetch the missing shards to target, then run there.

Fields

target: String

The node that receives the shards.

sources: Vec<String>

Complete holders that can serve them, by node id.

bytes: u64

Bytes that will move.

missing_shards: usize

Shards that will move.

Unplaceable(Unplaceable)

Not placeable, with the reason.
