How to optimize JSON serialization performance in Akka HTTP with Scala?
I'm trying to debug Could someone explain I've looked through the documentation and I'm still confused about I'm working on an Akka HTTP application using Scala 2.13 and Circe 0.14 for JSON serialization..... I noticed that the serialization process is taking a important amount of time, especially when dealing with large data sets. For instance, when serializing a case class with nested structures, the response time spikes, leading to performance bottlenecks. Here's my current case class definition: ```scala case class User(id: Int, name: String, address: Address) case class Address(street: String, city: String, zip: String) ``` And this is how I currently serialize it: ```scala import io.circe.generic.auto._ import io.circe.syntax._ val user = User(1, "John Doe", Address("123 Elm St", "Springfield", "12345")) val json = user.asJson ``` Although this works, I feel that the serialization is not as efficient as it could be. I tried using `io.circe.Printer` to customize the printer settings, but I didn’t notice any important improvement. Here's what I attempted: ```scala import io.circe.Printer val printer = Printer.noSpaces.copy(dropNullValues = true) val jsonOptimized = printer.print(user.asJson) ``` Still, the serialization time remains an scenario. I've also checked the Akka HTTP settings, ensuring that I have appropriate timeout configurations, but the question continues. I’m concerned about how this impacts the scalability of my service. Are there any specific strategies or best practices for optimizing JSON serialization with Circe in an Akka HTTP context? Should I consider using a different library, or are there configuration settings I might have missed? Any insights or examples would be greatly appreciated. I'm working on a CLI tool that needs to handle this. I'd really appreciate any guidance on this. What am I doing wrong? I'm working with Scala in a Docker container on CentOS. What are your experiences with this?
