You are designing the folder structure for an Azure Data Lake Storage Gen2 container.
Users will query data by using a variety of services including Azure Databricks and Azure Synapse Analytics serverless SQL pools. The data will be secured by subject area. Most queries will include data from the current year or current month.
Which folder structure should you recommend to support fast queries and simplified folder security?

  • A. /{SubjectArea}/{DataSource}/{DD}/{MM}/{YYYY}/{FileData}_{YYYY}_{MM}_{DD}.csv
  • B. /{DD}/{MM}/{YYYY}/{SubjectArea}/{DataSource}/{FileData}_{YYYY}_{MM}_{DD}.csv
  • C. /{YYYY}/{MM}/{DD}/{SubjectArea}/{DataSource}/{FileData}_{YYYY}_{MM}_{DD}.csv
  • D. /{SubjectArea}/{DataSource}/{YYYY}/{MM}/{DD}/{FileData}_{YYYY}_{MM}_{DD}.csv

Selected Answer: C
since we are querying b MM or year and data is secured by subject area. its better that we design the folder structure that does minimal scan of folder. here in this case we should first create year , month nd then service area

Selected Answer: D
Serverless SQL Pools offers a straight-forward method of querying data including CSV, JSON, and Parquet format stored in Azure Storage. So, setting up the csv files within azure storage in hive-formated folder hierarchy i.e. /{yyyy}/{mm}/{dd}/ actually helps in sql querying the data much faster since only the partitioned segment of the data is queried.
