You have an Azure Data Lake Storage Gen2 account named account1 and an Azure Event Hub named Hub1. Data is written to account1 using Event Hubs Capture.

You plan to query account1 using an Apache Spark pool in Azure Synapse Analytics.

You need to create a notebook to ingest the data from account1. The solution must meet the following requirements:

• Retrieve multiple rows of records in their entirety. • Minimize query execution time. • Minimize data processing.
