During May 2025, Lushiji focused on enhancing the apache/pulsar repository by upgrading its compression library dependencies to improve performance and build reliability, particularly for large-file processing scenarios. Leveraging skills in build management and dependency management, Lushiji updated both the commons-compress and zstd libraries using Shell and Text scripting. This targeted approach ensured that the build system remained stable and compatible with existing Pulsar features while delivering more efficient compression. The work addressed the need for up-to-date dependencies, directly supporting the project’s reliability and performance objectives. The scope was focused, with depth in dependency upgrades and build system maintenance.
