# CallImportance

Location: [gRPC API](https://developer.m-files.com/APIs/gRPC-API/index.md) > [Reference](https://developer.m-files.com/APIs/gRPC-API/Reference/index.md) > [Enums](https://developer.m-files.com/APIs/gRPC-API/Reference/Enums/index.md)

HTML version: https://developer.m-files.com/APIs/gRPC-API/Reference/Enums/MFiles.CallImportance/

Used by MFServer to distinguish between incoming calls of different
importance levels. For example, less important calls may be rejected
if the server is busy.

- **Full name:** `MFiles.CallImportance`
- **Proto file:** [`mfiles/enums.proto`](https://developer.m-files.com/APIs/gRPC-API/downloads/proto/mfiles/enums.proto)

## Values

| Name | Number | Description |
|---|---|---|
| <a id="v-CALL_IMPORTANCE_DEFAULT"></a>`CALL_IMPORTANCE_DEFAULT` | 0 | Call importance not set. Usually defaults to CALL_IMPORTANCE_NORMAL. |
| <a id="v-CALL_IMPORTANCE_NORMAL"></a>`CALL_IMPORTANCE_NORMAL` | 1 | Normal call. Calls of this type are never rejected. Multiple concurrent calls are served by concurrent threads in MFServer. Most calls should specify this importance level. |
| <a id="v-CALL_IMPORTANCE_CAN_BE_REJECTED"></a>`CALL_IMPORTANCE_CAN_BE_REJECTED` | 2 | A less important call, e.g. cache prefilling. This type of calls can be rejected by the server if it is currently too busy (e.g. servicing too many other calls). If MFServer rejects a call, E_MFILES_CALL_REJECTED is returned. |
