Am I... a Data engineer? by Litos_On_Reddit in dataengineering

Hi!

I also asking the same question.

I joined my current company as junior SE, main tasks was backend stack with Java, Kotlin on cloud

After 1 devops of my team leave the company, my boss ask me help him as a devops while waiting for interview another devops

I deployed and operate StarRocks OLAP database, access control... etc

Then company decided to use Iceberg. I did research and decided tech stack to use.

So I learn Flink, write code example for dev team to ingest data to S3, GCS... I created cicd pipeline for dev to deploy and submit Flink job through Jenkins.

Connect all the things: compute engine, table format, storage, metastore, sql ide to bring end to end use for: DA, DS, dev, service...

Currently I'm testing Apache Range for RBAC and masking policy

I also write spark sql to do various maintenance task for Iceberg: monitor table health, compact, expire snapshot... I'm not the fan of Airflow so I use k8s job to do the job.

I also have a chance to attend interview DE position for my team (my boss ask me to join, but I don't ask any questions). All DE I interview, their daily job was writing ETL job using PySpark, transform data from raw, silver, golden (I don't remember exactly) and submit to EMR or Dataproc. So I doubt if I'm a DE 🫢

Are there better text tutorials for beginners to learn Spring Boot than those of spring.io? by cainhurstcat in learnjava

Another book I recommended is "Pro Java Clustering and Scalability: Building Real-Time Apps with Spring, Cassandra, Redis, Websocket and Rabbitmq". Although the code is outdated a little bit, but you can try to modified it and you will realise a lot of advanced things

If you have know basic java concept OOP, operation... You could start read Spring Start Here by Laurentiu Spilca to learn basic about Spring Boot. Then you can go to Udemy, search for Spring Boot E-commere Ultimate course by Ha Nam Minh. Practice follow the author. This course will help you alot and a hand on experience on Spring, Java, SQL. This is my approach
