Prerequisites
To load a Parquet file from S3, the [`httpfs` extension](#docs:extensions:httpfs:overview) is required. This can be installed using the `INSTALL` SQL command. This only needs to be run once.  
```sql
INSTALL httpfs;
```  
To load the `httpfs` extension for usage, use the `LOAD` SQL command:  
```sql
LOAD httpfs;
```
