| Parameter | Type | Default value | Description |
|----------------------|------------|---------------|----------------------------------------------------------------------------------------------------------------------|
| `path` | `string` | | Path to the metabase file. |
| `capacity` | `size` | unrestricted | Approximate maximum size of the writecache. If the writecache is full, objects are written to the blobstor directly. |
| `small_object_size` | `size` | `32K` | Maximum object size for "small" objects. This objects are stored in a key-value database instead of a file-system. |
| `max_object_size` | `size` | `64M` | Maximum object size allowed to be stored in the writecache. |
| `flush_worker_count` | `int` | `20` | Amount of background workers that move data from the writecache to the blobstor. |
| `max_batch_size` | `int` | `1000` | Maximum amount of small object `PUT` operations to perform in a single transaction. |
| `max_batch_delay` | `duration` | `10ms` | Maximum delay before a batch starts. |
