Sylin.Koan.Data.Connector.InMemory

Use this connector for fast, process-local Entity persistence in tests, conformance suites, and explicitly ephemeral development workflows.

Choose it when

  • losing all data at process exit is acceptable;
  • a test needs a real AddKoan() provider without files, containers, or remote services; or
  • provider-neutral behavior needs a deterministic in-memory oracle.

Do not choose it for durable application state, cross-process sharing, or production recovery.

Install

dotnet add package Sylin.Koan.Data.Connector.InMemory

The direct package reference expresses intent to use the ephemeral provider. Keep the application's ordinary Koan bootstrap; there is no provider-specific registration:

builder.Services.AddKoan();

Meaningful result

Define an Entity and use its normal persistence verbs:

public sealed class Todo : Entity<Todo>
{
    public string Title { get; set; } = "";
}

var saved = await new Todo { Title = "Prove the rule" }.Save();
var same = await Todo.Get(saved.Id);

The saved value is available to every repository in the same Koan host and disappears when that host exits. InMemory stores a serialized snapshot, so mutating the original or a loaded value does not silently mutate persistence; call Save() again to publish a change. No files, container, or remote service are created.

Selection

The provider identity is inmemory (memory is also recognized). It is a direct provider with priority -100, not an automatic fallback. A direct InMemory reference wins over a merely bundle-provided automatic floor. If several Data connectors are referenced directly, Koan applies the normal deterministic selection rules; pin the intended provider when application durability must not change as references grow:

{
  "Koan": {
    "Data": {
      "Sources": {
        "Default": { "Adapter": "inmemory" }
      }
    }
  }
}

Current capability boundary

  • process-local concurrent storage keyed by source, Entity root, and partition;
  • detached, polymorphism-safe Entity snapshots on every read and write;
  • in-memory filter execution;
  • bulk upsert and bulk delete;
  • ordered, non-atomic batch behavior with atomic requirements rejected before mutation; and
  • shared/container/database isolation modes through the common key-value family.

The connector does not advertise DataCaps.Query.ProviderBoundedPaging. AllStream and QueryStream reject correctively with QueryStreamRejectedException before yielding because paging an already resident full-source dictionary is not a provider-bounded stream.

Use All/Query for deliberately small test sets, or FirstPage/Page when a bounded result returned to test code is sufficient. Numbered pages do not create an unbounded-data performance guarantee.

Physical compatibility maps and StorageLifecycle: External reject correctively: an object-graph store has no legacy physical names or pre-existing provider-owned storage to open. These are connector-specific claims, not a promise that remote providers behave identically. The current connector suite passes 56/56.

For application conformance, prefer Sylin.Koan.Testing; it owns host isolation, partitions, and the capability-aware battery. See TECHNICAL.md for the exact storage and negotiation contract.

Atomic insertion

Atomic insertion uses the existing host-owned, source/root/partition store. ConcurrentDictionary.TryAdd provides the insert-only decision over detached snapshots; an identity collision never replaces or returns the existing row. This is a single-process guarantee, consistent with InMemory storage. Default numeric keys reject before persistence; assign an identity when the Entity cannot generate one.
