Big Data processing is being democratised. Tools such as Azure Databricks, mean you do not need to be a Java expert to be a Big Data Engineer anymore. Databricks has made your life easier! While it is easier, there is still a lot to learn and knowing where to start can be quite daunting.
On the first day we will introduce Azure Databricks then discuss how to develop in-memory elastic scale data engineering pipelines. We will talk about shaping and cleaning data, the languages, notebooks, ways of working, design patterns and how to get the best performance. You will build an engineering pipeline with Python, then with Scala via Azure Data Factory, then we’ll get it into context in a full solution. We will also talk about Data Lakes – how to structure and manage them over time in order to maintain an effective data platform.
Second day we will then shift gears, taking the data we prepared and enriching it with additional data sources before modelling it in a relational warehouse. We will take a look at various patterns of performing data engineering to cater for scenarios such as real-time streaming, de-centralised reporting, rapidly evolving data science labs and huge data warehouses in specialised storage such as Azure SQL Datawarehouse. By the end of the day, you will understand how Azure Databricks sits at the core of data engineering workloads and is a key component in Modern Azure Warehousing.
