Synthetic Data Generation and Java Faker

Testing is often hard. Mostly because we need data to perform some forms of testing. For Unit Tests often you can fake your own data pretty easily. However, as we move to Integration Tests, E2E Tests, Big Data Data Science Discovery, Product(PO) Acceptance Testing, PO Discovery we might have a scaling issue. For sure you could build a tactical solution where you hardcoded all domains/data-sets of your company but this approach is highly coupled with systems database and is hard to maintain. So there are the tools and startups on the land of Synthetical Data Generation where they use metadata to understand databases and generate data because of constraints like size, type of data, verifications(CPF for Brazil, SSN for the US). This approach is hard but I believe is the future. Today I want to show something in that direction, but much more simple and maybe a starting point? Which is Java-Faker which is similar to Faker.js.

Kafka Streams with Java 15

Image
Kafka Streams is a Streaming library similar to Spark and Flink which works with Apache Kafka. Kafka stream can be useful to process historical and near-real-time big data workloads but also for non-realtime analytical computations at scale for the online world as well. Kafka-Streams is elastic, highly scalable, fault-tolerant, and fully integrated with Kafka. You can use Kafka Stream with Java, Scala, Kotlin JVM applications and also have exactly-once processing semantics. Kafka-Streams is being used by the New York Times, Pinterest, Line, Trivago, Zalando, and many other companies. Today I want to share a video of Kafka-Streams running with Kafka 2.6 and Java JDK 15. So Let's get started.

Rust and Java Interoperability

Image
Rust does not stop for one second to amaze me. It looks like Rust was designed to talk to every other language so easily. No kidding, it's clear way Web Assembly and rust have lots in common. Java is never an easy lang to interop with. Today I will show how easily we can interop Java & Rust. In order to do so, we will need to use the Java and Rust compilers. For Java, we will not require any other lib than the standard JDK. For Rust, we will need to create a lib project in cargo and we will need to use the crate JNI. I love this feature because java does not allow low-level code on the main language. So if we need to do something low level, efficiently Rust is my first choice, not only for safety reasons but because is really fast.  Let's get started.

HMAC in Java

Image
In 2018 AWS CTO(Vogels) said : "Security is everyone's job". For the last 2 years, there was so many famous and big data leaks and breaks that made that statement be very true more than ever. Security often could mean worst performance and worst user experience so in order to get it right you really need to think about the designs before jumping into to code and consider performance and user experience has main requirements.  I was thinking about writing about how to do HMAC in Java for a while and recently Redis 6.0.0 come out and to my surprise, there was a refactoring on the password part in order to use HMAC.  Security easily could scare engineers often because it is not something well spread yet but I believe this will change soon. It does not matter if you have to deal with PII Data or not, security is super relevant because everybody is running their workloads at the cloud or with IoT and Edge devices which means more distribution, more code, more points of fail
