When should I use gRPC vs REST?

gRPC makes better use of HTTP/2 then REST. gRPC for example makes it possible to turn-off message compression. This might be useful if you want to send an image that is already compressed. Compressing it again just takes up more time.

Is gRPC more secure than REST?

Both gRPC and REST communications are secured with TLS/SSL. Streaming is bidirectional in gRPC, while only 1 way request from client to server in REST. So gRPC is better than REST for most of the things that we’ve mentioned so far.

Can gRPC replace REST API?

Understanding Microservices, REST APIs and RPC APIs Not only do APIs make microservices-based applications possible, but it’s in the context of microservices-based applications that gRPC APIs can — in some cases — serve as an alternative to REST APIs.

What are the advantages of gRPC?

Microservices: gRPC is designed for low latency and high throughput communication. gRPC is great for lightweight microservices where efficiency is critical. Point-to-point real-time communication: gRPC has excellent support for bi-directional streaming. gRPC services can push messages in real-time without polling.

When should use gRPC?

1. When the microservices is only internal and when one server needs to talk to the other.
2. When your internal services requires duplex streaming with high load of data.
3. When you don’t feel to write client libraries.

What is the advantage of gRPC over rest?

Compared to REST, gRPC provides greater performance at the expense of less flexibility. So, gRPC does not provide a set of guidelines on how to create web APIs; it enforces rules. This time, the mailman would be very angry if you didn’t start the letter with a proper salutation!

When should I use Stream API?

Streaming API is used when you need to keep your external source in sync with the Salesforce data with PushTopic events and Change Data Capture events. Streaming API lets you process business logic in an external system in response to data changes in Salesforce.

Is gRPC faster than rest?

“gRPC is roughly 7 times faster than REST when receiving data & roughly 10 times faster than REST when sending data for this specific payload. This is mainly due to the tight packing of the Protocol Buffers and the use of HTTP/2 by gRPC.”
