Data Engineer
A data engineer plays a central role in a company and is responsible for setting up the infrastructure required for data collection, storage, conversion and management. They ensure that the data collected from various sources is organized and accessible to stakeholders and can be analyzed by data scientists and analysts.
Data Engineers typically work on tasks such as developing and managing data pipelines, extracting, transforming and loading data (ETL processes) and cleansing data to ensure it is suitable for analysis. They may also specialize in areas such as data storage, programming and pipelines or analytics, depending on the specific needs of their organization.
Over the course of their career, data engineers may progress from junior positions, where they focus on learning and gaining hands-on experience, to senior positions where they take on more leadership responsibilities and strategic planning. A typical data engineering project may include tasks such as identifying data requirements, extracting and preparing data, and creating endpoints for data access.
Overall, data engineers play an important role in helping organizations leverage their data assets to drive business success and support decision-making processes.
Data Lakehouse
Data engineers should understand the concept of the data lakehouse, as it represents a significant evolution in data management, seamlessly integrating the benefits of data lakes and data warehouses to provide scalable storage and processing capabilities essential for modern organizations.
Purpose and Architecture:
A data lakehouse serves as a comprehensive data management system for modern organizations that require scalable storage and processing capabilities. It addresses the challenges that arise from siloed systems used for different workloads such as machine learning (ML) and business intelligence (BI). The architectural design follows a medallion pattern, where data is extended incrementally through different implementation and transformation phases. The core technologies in Databricks Lakehouse are Apache Spark, Delta Lake for optimized storage with ACID transactions and schema enforcement, and Unity Catalog for unified, fine-grained governance for data and AI.
Data Ingestion:
At the first layer, data arrives in raw formats through batch or streaming processes. This logical layer provides a landing pad for raw data prior to conversion to delta tables. Delta Lake’s schema enforcement capabilities ensure data compliance during this process. Unity Catalog is used for table registration, alignment with data governance models, and setting data isolation boundaries, which are essential for maintaining data privacy and security.
Data Processing, Curation, and Integration:
Once the data is verified, the curation and refinement phase begins. Data scientists and machine learning experts work together, combining or creating new features and performing thorough data cleansing. The schema-on-write approach combined with delta schema evolution capabilities enables changes to this layer without disrupting downstream logic, providing the flexibility to adapt to changing business needs.
Data Serving:
The final layer provides end users with clean, enriched data designed for different use cases. A unified governance model ensures that data provenance can be traced back to the single source of truth. Optimized data layouts for different tasks enable end users to access data for machine learning, data engineering, business intelligence and reporting applications.
Capabilities of a Databricks Lakehouse:
A Databricks Lakehouse replaces the dependencies of traditional data lakes and warehouses and offers a range of features. These include real-time data processing, data integration for a single source of truth, schema evolution to adapt to changing business needs, data transformations for speed and reliability, and data analytics and reporting with an engine optimized for warehousing workloads. It also supports machine learning and AI, data versioning, data lineage tracking, comprehensive data governance, data sharing and operational analytics.
Data Warehouse vs. Data Lake vs. Data Lakehouse:
The distinction between lakehouse and data lake or data warehouse is critical. While data warehouses have formed the basis for BI decisions for decades, their limitations lie in query speed and adaptability to changing data. Data lakes, on the other hand, store and process various data efficiently, but do not provide support for BI reports due to their non-validated nature.
The data lakehouse combines the benefits of data lakes and data warehouses, offering open access to data stored in standard formats. It employs optimized indexing for machine learning and data science tasks, ensuring low query latency and high reliability for business intelligence and advanced analytics.
