chebbyChefNEQ opened a new issue, #6469:
URL: https://github.com/apache/arrow-rs/issues/6469
**Describe the bug**
Cloud based (tested for GCS) store builder blocks on file IO synchronously
in `.build`. This happens by:
`object_store` -> `reqwest::ClientBuild::build` -> `rustls::load_native_cert`
**To Reproduce**
```rust
use object_store::gcp::GoogleCloudStorageBuilder;
fn main() {
for _ in 0..100 {
let start = std::time::Instant::now();
let _gcs =
GoogleCloudStorageBuilder::from_env().with_bucket_name("some-bucket").build().unwrap();
println!("built in: {:?}", start.elapsed());
}
}
```
**Expected behavior**
calling `build` should return a future and not block
**Additional context**
I'll create a ticket in `reqwest` as well, but maybe we could capture the
client build in `tokio::spawn_blocking` for the time being?
