this feature, in addition to the *what*)
-->
Deleting a lot of objects from an `ObjectStore` can be expensive if you have
to do a separate API call for each object. In scenarios where you have to
delete a lot of objects in a batch (eg a compaction process) this can be very
annoying and resource intensive.
It would be helpful to add a `bulk_delete` method to `ObjectStore` that can
take advantage of underlying APIs that allow for bulk deletion (eg S3
`DeleteObjects` API).
The default implementation can just call `delete` on each path serially if
the underlying `ObjectStore` does not have an API for bulk deletion or we can
throw an unimplemented error instead.
**Describe the solution you'd like**
<!--
A clear and concise description of what you want to happen.
-->
pub struct BulkDeleteResult {
/// Count of objects successfully deleted
deleted: usize,
/// Errors for individual objects which could not be deleted for some
reason,
errors: Vec<(Path,Error)>,
}
Something like
```
pub trait ObjectStore {
async fn bulk_delete(&self, locations: &[Path]) ->
Result<BulkDeleteResult>;
}
```
