Properties

CreatedAt

When the instance was started.

CursorJson

Engine cursor state (graph positions); null before the first checkpoint. Same JSON-document semantics as DataJson.

DataJson

The serialized TData document. This is a JSON document, not an opaque string: providers may store it in a native JSON column (jsonb etc.) and must preserve semantic content — lexical formatting (whitespace, object key order) need not survive.

DefinitionId

Which workflow this is an instance of.

DefinitionVersion

The definition version this instance is pinned to.

Id

Engine-generated identity; opaque to providers, which never mint or order by it.

Revision

Optimistic concurrency token. CreateInstanceAsync stores 1; each successful UpdateInstanceAsync(expectedRevision) stores expectedRevision + 1.

State

Where the instance is in its lifecycle.

TenantId

The owning tenant, or null.

UpdatedAt

When the instance was last checkpointed.
