Hugo.Deterministic.Cosmos

Deterministic state store implementation for Hugo workflows backed by Azure Cosmos DB. It persists version gates and deterministic effects so replayed workflows return the same outcomes.

Install

dotnet add package Hugo.Deterministic.Cosmos

Configure

builder.Services.AddSingleton<IDeterministicStateStore>(sp => { CosmosClient client = new("https://your-account.documents.azure.com", "key"); return new CosmosDeterministicStateStore(client, databaseId: "hugo", containerId: "deterministic"); });

Notes

• Requires an existing Cosmos DB container with partition key /changeId.
• Supports optimistic writes for gates and effect records; conflicting writes return error.version.conflict.
