- SSE-C is hardly adopted by most widely used applications, applications prefer server to manage the keys via SSE-KMS or SSE-S3.
- MinIO recommends applications to use SSE-KMS, SSE-S3 for simpler, safer and robust encryption mechanism for replicated buckets.

```yaml
meshConfig:
  accessLogFile: /dev/stdout
```

#### Revisions

Control plane revisions allow deploying multiple versions of the control plane in the same cluster.
This allows safe [canary upgrades](https://istio.io/latest/docs/setup/upgrade/canary/)

```yaml
revision: my-revision-name

Erasure code protects data from multiple drives failure, unlike RAID or replication. For example, RAID6 can protect against two drive failure whereas in MinIO erasure code you can lose as many as half of drives and still the data remains safe. Further, MinIO's erasure code is at the object level and can heal one object at a time. For RAID, healing can be done only at the volume level which translates into high downtime. As MinIO encodes each object individually, it can heal objects incrementally....

### High availability

A stand-alone MinIO server would go down if the server hosting the drives goes offline. In contrast, a distributed MinIO setup with _m_ servers and _n_ drives will have your data safe as long as _m/2_ servers or _m*n_/2 or more drives are online.

Consult our security experts on [SUBNET](https://min.io/pricing) to help you evaluate if
your setup can use this feature combination safely.

To enable compression+encryption use:

```bash
~ mc admin config set myminio compression allow_encryption=on
```

Or alternatively through the environment variable `MINIO_COMPRESSION_ALLOW_ENCRYPTION=on`.

### 4. Excluded Types

## Enabling Parquet Format

Parquet is DISABLED by default since hostile crafted input can easily crash the server.

If you are in a controlled environment where it is safe to assume no hostile content can be uploaded to your cluster you can safely enable Parquet.
To enable Parquet set the environment variable `MINIO_API_SELECT_PARQUET=on`.

## Example using Python API

mc: Decryption key: ad2b43d847fdb14e54c5836200177f7158b3f745433525f5d23c0e0208e50c9948540b54

mc: The decryption key will ONLY be shown here. It cannot be recovered.
mc: The encrypted file can safely be shared without the decryption key.
mc: Even with the decryption key, data stored with encryption cannot be accessed.
