Data lakehouse is a relatively new concept of querying data directly and in the same way no matter if the data is in data lake or in relational data warehouse. Lets see how we could implement it in Synapse! You will be amazed of how many options we have for data exploration in Synapse, you will see new ways to architect data analytics by combining multiple data sources ad hoc. We will build a common report from data stored in ADL and in Cosmos DB, and we will show it in PBI. All in Synapse! You will see the concept of Data Lakehouse in action! And of course we will discuss when to use what, because this is the key to build a good solution!
