Configuration for ParameterServer.

Fields

embedding_dim: usize

Embedding dimensionality (length of each row).

num_entities: usize

Total number of entity rows the server will own (across all shards).

num_relations: usize

Total number of relation rows the server will own.

num_shards: usize

Number of shards to split the entity table into.

expected_workers: usize

Number of workers expected to push per step in UpdateMode::Sync.

update_mode: UpdateMode

Sync/async update mode.

learning_rate: f32

Optimizer learning rate applied during push.

max_staleness: u64

Maximum staleness tolerated in async mode before logging a warning.

barrier_timeout: Duration

Per-step barrier timeout in UpdateMode::Sync; if exceeded, the barrier proceeds with whatever pushes have arrived.
