javalin VS Apache Avro

If you've read this far, you might be interested to know that Javalin has been offering Brotli compression through jvm-brotli for three years already, and that there have been no (reported) issues. In other words, the effort required to release and maintain this is probably not huge.

I'm a big fan of Ktor (ktor.io) but another reasonable lightweight alternative is Javelin (https://javalin.io/). Heck even Spring Boot isn't that bad. HikariCP + JooQ (has both java and kotlin codegen) for DB access if you need and you're good to go.

A similar alternative that does not rely on web sockets is https://htmx.org. I have greatly enjoyed using it with some simpler web frameworks like https://javalin.io to do some prototyping and smaller projects. I'm sure if someone made a plug and play UI library like material UI for Angular on top of htmx you could absolutely fly through MVPs.

Javalin

If you're already familiar with most of the concepts around HTTP and web services, I'd recommend using something like https://javalin.io/ which is light weight frame work that makes getting something up and running quickly a very easy task.

I've been looking at https://javalin.io/ Seems close enough to express and some big names are using it, so I wouldn't say it's fizzling out

Javalin (https://javalin.io) is strongly inspired by Express and Koa, so you should feel right at home:

If you want to do a proper comparison between the two, I would be happy to help with code examples from Javalin's side. I could even host it on https://javalin.io as a "Comparison to Jooby" blog post.

Apache AVRO [1] is one but it has been largely replaced by Parquet [2] which is a hybrid row/columnar format

The most common format for describing schema in this scenario is Apache Avro.

I am testing a new schema registry which loads and retrieves different kinds of avro schemas. In the process of testing, I need to create a bunch of different types of avro schemas. As it involves a lot of permutations, I decided to create the schema programmatically.I am using the apache avro SchemaBuilder to do so.

Other serialization alternatives have a schema validation option: e.g., Avro, Kryo and Protocol Buffers. Interestingly enough, gRPC uses Protobuf to offer RPC across distributed components:

Once things like JSON became more popular Apache Avro appeared. You can define Avro files which can then be generated into Python, Java C, Ruby, etc.. classes.

Supporting multiple versions of an event schema is a solved problem. Apache Avro with a published schema hash in a message header is one solution.
