`default` subsection has the same format and specifies defaults for missing values.
The following table describes configuration for each shard.

| ------------------------------------------------ | ------------------------------------------- | ------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `compress` | `bool` | `false` | Flag to enable compression. |
| `compression_level` | `string` | `optimal` | Compression level. Available values are `optimal`, `fastest`, `smallest_size`. |
| `compression_exclude_content_types` | `[]string` | | List of content-types to disable compression for. Content-type is taken from `Content-Type` object attribute. Each element can contain a star `*` as a first (last) character, which matches any prefix (suffix). |
| `compression_estimate_compressibility` | `bool` | `false` | If `true`, then noramalized compressibility estimation is used to decide compress data or not. |
| `compression_estimate_compressibility_threshold` | `float` | `0.1` | Normilized compressibility estimate threshold: data will compress if estimation if greater than this value. |
| `mode` | `string` | `read-write` | Shard Mode.<br/>Possible values: `read-write`, `read-only`, `degraded`, `degraded-read-only`, `disabled` |
| `resync_metabase` | `bool` | `false` | Flag to enable metabase resync on start. |
