Kw Nam contributed to the juicedata/juicefs repository by developing features that enhanced file system security, access control, and quota visibility. Over four months, they implemented configurable umask and mount permission options, including an all-squash feature and AnonymousAccount refactor, to improve multi-tenant safety and operational consistency. Their work included adding quota retrieval APIs in Go and exposing these details in the Java SDK, aligning interface behavior across languages and supporting Hadoop compatibility. Kw Nam also introduced subdirectory access controls and clarified cache configuration documentation, demonstrating depth in API development, configuration management, and cross-language SDK integration using Go, Java, and Markdown.

Apr 1, 2025April 2025 monthly summary for juicedata/juicefs focused on quota visibility and cross-language interface consistency. Implemented quota exposure end-to-end, enabling users to view quota (maximum space and inodes) directly from the File struct (GetQuota) and ensuring these details are surfaced in the Java SDK and JuiceFS Java integration (JuiceFileSystemImpl and jfs_summary). This work aligns with Hadoop compatibility goals by enabling quota visibility in Hadoop commands, addressing the gap noted in (#5939). Resulting changes improve capacity planning, reduce manual checks, and provide a stable foundation for quota-based policies across Go and Java components. Technologies/skills demonstrated: Go API design (File.GetQuota), Java SDK integration (jfs_summary, JuiceFileSystemImpl), cross-language interface consistency, API surface alignment, and performance/reliability considerations for quota reporting.
