They utilize the high-performance Cap'n Proto serialization/RPC protocol, which ensures efficient data exchange with reduced processing overheads. This protocol's capabilities, including zero-copy deserialization, make it superior to alternatives like JSON or XML. Developers with Cap'n Proto expertise can also build more efficient, faster, and safer systems. They enable real-time data processing, saving time and resources, and increasing application performance. Their skills can be critical in projects requiring high speed, safety, and efficiency in data serialization and inter-process communication.
