What is Binary Large Objects?
Binary Large Objects (BLOBs) are collections of binary data stored as a single entity in a database management system. These files often include multimedia formats like images, audio files, and videos but can also include binary executable code or any other data type that needs to be stored as a whole.
Functionality and Features
BLOBs are convenient for storing large amounts of binary data on a database server. They support efficient writing and reading of large unstructured data, including streaming capabilities. BLOBs are typically used to hold multimedia objects such as images and audio, but they can also store serialized objects and uncompressed data.
Benefits and Use Cases
BLOBs play an integral role in many business and software applications due to their ability to handle unstructured, typically large, data files. They are essential for applications dealing with multimedia, like media streaming apps, image databases, and audio libraries. Long document data storage in electronic document management systems is another significant use case. BLOBs also support data backup and data archiving systems.
Challenges and Limitations
While BLOB data types are efficient for handling large quantities of binary data, they also propose some challenges. They can consume substantial amounts of server memory and potentially slow down the database. Additionally, BLOB data is often difficult to search and index effectively.
Integration with Data Lakehouse
A data lakehouse tries to combine the advantages of Data Lakes and Data Warehouses. Binary Large Objects can be efficiently managed in a data lakehouse setup. Data Lakehouse supports both structured and unstructured data types, making it a perfect fit for managing BLOBs. The massive scalability of a data lakehouse can also handle the size and complexity of BLOBs, and it enables high-speed data processing for analytics.
Comparison with Dremio's Technology
Compared to traditional BLOB storage in relational databases, Dremio's Data Lakehouse platform provides a higher level of flexibility and scalability. It handles structured and unstructured data, including BLOBs, and delivers high-speed analytics. Additionally, Dremio's platform offers efficient indexing and search, overcoming some limitations of traditional BLOB storage.
Security Aspects
While storing BLOBs in databases or data lakehouses, security measures such as encryption and access controls are crucial to maintain data privacy. This is especially important when dealing with sensitive data, like personal or financial information.
Performance
The performance impact of BLOB storage is dependent on the size and number of BLOBs. Large or numerous BLOBs may consume significant server memory, potentially affecting database performance.

Glossary
Data Lakehouse: A new architectural paradigm that combines the best attributes of classic data warehouses and modern data lakes.
Unstructured Data: Information that either does not have a predefined data model or is not organized in a pre-defined manner.
Data Lake: A large storage repository and processing engine, often in the cloud, that can hold and analyze large amounts of raw data in various formats.
Data Warehouses: Central repositories of integrated data from one or more disparate sources, used for reporting and data analysis.
Relational Databases: A type of database that stores and organizes data in tables and allows for relationships between different types of data.
