Rajas Kakodkar developed a stream-optimized VMDK writer for the vmware/govmomi repository, enabling the creation of compressed VMDK files directly from raw disk images. Using Go, Rajas implemented zlib-based compression and optimized the handling of zero-filled grains to reduce storage requirements and improve I/O efficiency. The solution incorporated robust error handling through an Abort() mechanism and supported partial grain writes, enhancing reliability during disk operations. Comprehensive testing, including scenarios with 1TB disk images, validated scalability and correctness. The design aligned with the existing vmdk package reader and followed open-vmdk guidance to ensure compatibility and future extensibility.
