How Python Data Engineers Use Azure Data Lake Storage

Data engineers use ADLS Gen2 as the central data lake in Azure architectures. Python pipelines access it via the `azure-storage-file-datalake` SDK to manage directory structures, set ACLs on sensitive data partitions, and list/read Parquet files for processing. Synapse Analytics and Databricks mount ADLS as a file system for direct DataFrame reads.
