GitHub user Xuanwo edited a discussion: OpenDAL Compat
Hi, OpenDAL occasionally releases breaking changes. Each time this happens, our
users need to update their versions. It's straightforward if users only depend
on `opendal` itself.
However, since `opendal` is widely used, it's possible that users also depend
on crates like `iceberg`, `parquet`, and `delta`, which depend on `opendal` as
well. Those projects might have different release schedules that can't align
with opendal's release.
Releasing `opendal 1.0` might help, but it still needs time. Even `opendal 1.0`
can't fully address this, as not every crate can update to the new version
promptly.
So I propose a new crate called `opendal_compat`. In which, we provide API like:
```rust
#[feature("v50_to_v49")]
fn v50_to_v49(v: opendal_v50::Operator) -> opendal_v49::Operator { ... }
```
This way, users can always convert the newer opendal versions to the old ones
for compatibility.

The conversation isn't endless: we might only provide the two most recent major
versions.
