Detailed Description

Host-owned durable store boundary for compiled fragments and task state.

Every operation is awaitable (#556); a store whose backend is synchronous completes it at once (SyncTaskGraphFragmentStore). The arguments of a call, string views included, must stay alive until the awaitable completes: await it in the full expression that makes the call.

Member Function Documentation

find_published()

virtual asio::awaitable< std::optional< TaskGraphFragmentRecord > > neograph::program::TaskGraphFragmentStore::find_published ( std::string_view  owner_scope, std::string_view  parent_run_id, std::string_view  expansion_operation_id, std::string_view  proposal_hash  ) const

inlinevirtual

Locate an already published expansion by immutable parent lineage and proposal identity.

The default is deliberately empty for legacy stores; such stores remain safe but cannot recover an expansion without replanning.

Reimplemented in neograph::program::SyncTaskGraphFragmentStore.

find_published_lineage()

virtual asio::awaitable< std::optional< TaskGraphFragmentRecord > > neograph::program::TaskGraphFragmentStore::find_published_lineage ( std::string_view  owner_scope, std::string_view  parent_run_id, std::string_view  expansion_operation_id  ) const

inlinevirtual

Locate the published expansion for one immutable parent operation.

This lookup is used before reading the proposal source during recovery. A durable fragment is the source of truth after publication; the proposal is only needed on the first execution or when no fragment has crossed the publication boundary.

Reimplemented in neograph::program::SyncTaskGraphFragmentStore.
