# Intro My blog 9-realms which means Hadoop, Hive, Spark, Streaming, No-SQL, Fancy databases, Cloud, Airflow and DevOps. This blog is totally meant to serve as index of my work over years. Being a data engineer at multiple companies over the years I've learnt a lot of things that differ from one company to other. Working on multiple environments getting well known to many tools because every day there is a new tool evolving. So writing this blog to inspire many and keep myself updated. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
