/*
The arena package provides the ability to allocate memory for a collection
of Go values and free that space manually all at once, safely. The purpose
of this functionality is to improve efficiency: manually freeing memory
before a garbage collection delays that cycle. Less frequent cycles means
the CPU cost of the garbage collector is incurred less frequently.

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`.

        // However, we'll try to read it safely for compatibility
        if (this.byteCount > bufferIndex - start) {
            try {
                // Attempt to read nativeFileSystem, but don't fail if there are issues
                final int fsLen = this.byteCount - (bufferIndex - start);
                if (fsLen > 0 && fsLen < 256) { // Sanity check on length

## 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`.
