Comparing gRPC vs REST for File Transfer: Implementation and Performance Analysis
By

Sesame, salt, and substance. A flagship bake.
Summary
This technical blog post explores whether gRPC or REST is better for file transfer implementations. The author compares both approaches by implementing file transfer services in each technology, testing them with Kreya, and analyzing performance differences. Key challenges discussed include the importance of streaming large files to avoid memory issues, and the article provides practical implementation guidance for developers working with file transfer systems.

· 4 pulledIs transfering files with gRPC a good idea? Or should that be handled by a separate REST API endpoint?
When handling large files, it is important to stream the file from one place to another.
This might sound obvious, but many developers (accidentally) buffer the whole file in memory, potentially leading to out-of-memory errors.
In this post, we will implement a file transfer service in both, use Kreya to test those APIs, and finally compare the performance to see which one is better.
