Crate iceberg_storage_opendal 

OpenDAL-based storage implementation for Apache Iceberg.

This crate provides OpenDalStorage and OpenDalStorageFactory, which implement the Storage and StorageFactory traits from the iceberg crate using OpenDAL as the backend.

Backend-independent client settings shared by every OpenDalStorage variant.

OpenDalResolvingStorage

A resolving storage that auto-detects the scheme from a path and delegates to the appropriate OpenDalStorage variant.

OpenDalResolvingStorageFactory

A resolving storage factory that creates OpenDalResolvingStorage instances.

Enums

OpenDalStorage

OpenDAL-based storage implementation.

OpenDalStorageFactory

OpenDAL-based storage factory.

Constants

OPENDAL_IO_TIMEOUT_MS

Timeout in milliseconds for each IO call on a reader, writer, lister or deleter, applied per retry attempt via OpenDAL’s TimeoutLayer::with_io_timeout. Defaults to 10 seconds.

Traits

ProvideCredential

Trait for types that can asynchronously supply AwsCredential to a CustomAwsCredentialLoader. ProvideCredential is the trait used by signer to load the credential from the environment. ` Service may require different credential to sign the request, for example, AWS require access key and secret key, while Google Cloud Storage require token.
