Workflow Approval History
The WorkflowApprovalHistory collection is part of the MongoDB database schema used by Workflow Engine. The WorkflowApprovalHistory collection stores approval decisions associated with process instances. This page lists the collection indexes and explains the field model used by MongoDB for this persistence object.
Document fields
The WorkflowApprovalHistory collection does not define a fixed field list at the MongoDB database level. Workflow Engine documents in this collection can therefore evolve without a relational column definition.
Database indexes
The WorkflowApprovalHistory collection defines 3 database indexes. Definitions retain the column or field order and sort direction used by the database.
| Index | Unique | Definition |
|---|---|---|
IdentityId_1 | No | IdentityId 1 |
ProcessId_1 | No | ProcessId 1 |
_id_ | Yes | _id 1 |
