GitHub user theelderbeever closed a discussion: Example for reading from a delta table

As the title says. Looking for an example on how to read from a deltalake table. Is this even possible yet? I have started with something like below. Do I need to implement my own TableProvider somewhere or does anyone know if one already exists?

```rust
    let mut table = match open_table("data/metrics").await {
        Ok(tbl) => tbl,
        Err(_) => {
            let ops = DeltaOps::try_from_uri("data/metrics").await?;
            ops.create()
                .with_table_name("metrics")
                .with_columns(VectorMetric::columns())
                .await?
        }
    };

    let mut ctx = SessionContext::new();

    ctx.register_table("metrics", Arc::new(table)).unwrap();
```
