Why was gRPC chosen for the aggregation service in this case?

gRPC is chosen for the aggregation service due to several key advantages:

• High performance and low latency: gRPC uses HTTP/2 and the binary Protobuf protocol, which ensures efficient serialization and fast data transfer.
• Well-defined contract: Protobuf describes services and messages, simplifying integration and reducing errors.
• Streaming support: gRPC allows for bidirectional streaming, which is convenient for real-time data aggregation.
• Request multiplexing: HTTP/2 enables multiple requests to be processed simultaneously over a single connection, improving scalability.

In the context of an aggregation service, where it is necessary to quickly and efficiently collect data from various sources and deliver it to clients, gRPC provides an optimal balance between performance and ease of development.
