Worked on performance and memory management improvements for ArrowStreamWriter in both the apache/arrow-dotnet and mathworks/arrow repositories. Focused on reducing memory allocations and improving streaming throughput for large datasets, the work involved refactoring to use pooled buffers and MemoryAllocator for temporary buffers, as well as introducing a TryCompress method on the ICompressionCodec interface for more efficient compression handling. All allocated memory was properly disposed to minimize GC pressure and resource leaks. These enhancements, implemented in C#, emphasized memory pooling, resource management, and performance optimization, resulting in a unified, memory-conscious streaming path across .NET Arrow implementations for large-scale data processing.
