Model distribution service for AI/ML model deployment

Provides model-specific distribution with variant selection, convergence tracking, and rollback capabilities.

Required Methods

fn distribute_model<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model_id: &'life1 str, version: &'life2 str, scope: DistributionScope, priority: TransferPriority, ) -> Pin<Box<dyn Future<Output = Result<ModelDistributionHandle>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Distribute a model version to target platforms

Selects appropriate variant based on target capabilities and initiates distribution. Variant selection considers GPU memory, CPU architecture, and available execution providers.

Arguments

• model_id - Model identifier (e.g., “target_recognition”)
• version - Semantic version (e.g., “4.2.1”)
• scope - Target platforms (all, formation, specific nodes, capable)
• priority - Transfer priority

Returns

Handle for tracking distribution progress

fn distribute_model_variant<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, model_id: &'life1 str, version: &'life2 str, variant_id: &'life3 str, scope: DistributionScope, priority: TransferPriority, ) -> Pin<Box<dyn Future<Output = Result<ModelDistributionHandle>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Distribute a model with explicit variant selection

Use when automatic variant selection is not desired.

fn distribute_model_delta<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, model_id: &'life1 str, from_version: &'life2 str, to_version: &'life3 str, scope: DistributionScope, ) -> Pin<Box<dyn Future<Output = Result<ModelDistributionHandle>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Distribute model delta (differential update)

For large models, only transfer changed chunks between versions. Requires target platforms to have from_version locally.

Note

Delta updates use content-defined chunking to minimize transfer size. If target doesn’t have from_version, falls back to full distribution.

fn convergence_status<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model_id: &'life1 str, target_version: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<ModelConvergenceStatus>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Get convergence status for a model version

Returns detailed status of how many platforms have converged to the target version, what’s blocking others, and estimated completion.

fn rollback<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model_id: &'life1 str, to_version: &'life2 str, scope: DistributionScope, ) -> Pin<Box<dyn Future<Output = Result<ModelDistributionHandle>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Initiate rollback to a previous version

Distributes the previous version to all platforms that have the current (problematic) version.

fn node_model_status<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model_id: &'life1 str, node_id: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Option<NodeModelStatus>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Get model status on a specific node

fn nodes_with_version<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model_id: &'life1 str, version: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Vec<NodeModelStatus>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

List all nodes with a specific model version

fn cancel<'life0, 'life1, 'async_trait>( &'life0 self, handle: &'life1 ModelDistributionHandle, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Cancel an in-progress model distribution

fn subscribe_convergence<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, model_id: &'life1 str, target_version: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<Receiver<ModelConvergenceStatus>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Subscribe to convergence status updates
