Workflow Process Instance Persistence
The WorkflowProcessInstancePersistence collection is part of the MongoDB database schema used by Workflow Engine. The WorkflowProcessInstancePersistence collection stores persisted parameter values for process instances. This page lists the collection indexes and explains the field model used by MongoDB for this persistence object.
Document fields
The WorkflowProcessInstancePersistence 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 WorkflowProcessInstancePersistence collection defines 3 database indexes. Definitions retain the column or field order and sort direction used by the database.
| Index | Unique | Definition |
|---|---|---|
ProcessId_1 | No | ProcessId 1 |
ProcessId_1_ParameterName_1 | Yes | ProcessId 1, ParameterName 1 |
_id_ | Yes | _id 1 |
