Overview
Deprecation warning: the lakeFS Java SDK InternalApi class contains 54 methods marked with @Deprecated annotations that may be removed in future releases.
Description
The InternalApi class in the lakeFS Java SDK has a large number of methods annotated with @Deprecated. These deprecated methods represent older API variants that have been superseded by newer implementations. The deprecated methods include operations related to getLakeFSVersion, internal metadata endpoints, and various admin operations. When these methods are removed in a future lakeFS release, any code relying on them will break.
Usage
Apply this heuristic when writing Java code that calls InternalApi methods. Before using any InternalApi method, check whether it is marked @Deprecated in the source. If so, find the non-deprecated replacement method or consult the lakeFS migration guide.
The Insight (Rule of Thumb)
- Action: Before calling any InternalApi method, verify it is not @Deprecated in the current SDK version.
- Value: 54 methods are currently deprecated in the InternalApi class (out of approximately 100+ methods).
- Trade-off: Migrating away from deprecated methods requires code changes, but prevents breakage on SDK upgrades.
- Recommendation: Prefer the non-deprecated method variants. Where a deprecated method has no clear replacement, consult the lakeFS changelog or API documentation.
Reasoning
The lakeFS project follows semantic versioning and marks methods as deprecated before removal. The high count of deprecated methods (54) in InternalApi indicates an ongoing API migration. Code that continues to use deprecated methods risks breaking on the next major version bump. The deprecation annotations serve as an explicit signal from the maintainers that these methods are no longer the recommended path.
