You deploy an application that performs sentiment analysis on the data stored in Azure Cosmos DB.

Recently, you loaded a large amount of data to the database. The data was for a customer named Contoso, Ltd.

You discover that queries for the Contoso data are slow to complete, and the queries slow the entire application.

You need to reduce the amount of time it takes for the queries to complete. The solution must minimize costs.

You plan to implement a new data warehouse for a planned AI solution.

You have the following information regarding the data warehouse:

– The data files will be available in one week.

– Most queries that will be executed against the data warehouse will be ad-hoc queries.

– The schemas of data files that will be loaded to the data warehouse will change often.

– One month after the planned implementation, the data warehouse will contain 15 TB of data.

You need to recommend a database solution to support the planned implementation.

Box 1: Azure Blob Storage

The following technologies are recommended choices for batch processing solutions in Azure.

Data storage

– Azure Storage Blob Containers. Many existing Azure business processes already use Azure blob storage, making this a good choice for a big data store.

– Azure Data Lake Store. Azure Data Lake Store offers virtually unlimited storage for any size of file, and extensive security options, making it a good choice for extremely large-scale big data solutions that require a centralized store for data in heterogeneous formats.
