Data Warehouse vs Data Lakehouse vs Data Lake: A Quick Overview

Data Warehouse:

While the warehouse is a self-explanatory word, for data it is a term used for a repository either on-premise or cloud, that stores structured data from various sources, which can then be used for analytics, reporting, and business intelligence.

Data warehouses (1980s) act as centralized storage units for the exorbitant data that large-scale companies generate daily. Independent data reveals that approx. 54% of organizations globally use data warehouses, and it is expected to grow at a CAGR of 10.7%. Popular data warehouses used worldwide include Google BigQuery, Snowflake, Microsoft Azure Synapse Analytics, IBM Db2 Warehouse, etc.

Data Lake:

While data warehouse services helped organizations deal with data there was one problem, the data had to be structured. As technology grew organizations started generating data in the form of a lot of images, and videos, besides text and this is where Data Lakes (2010) came in.

Data Lake has become a go-to solution for organizations looking for a data storage solution that offers a lot of flexibility and is capable of dealing with a lot of raw and unstructured data, and is expected to touch $17.6 billion by 2026, with a CAGR of 29.9%. It is a solution ideal for the growing needs of your large-scale organization and it is expected that almost 60% of organizations will adopt data lakehouse solutions by 2026.

Data Lakehouse:

While a part of the world steered towards data warehouses and the remaining towards data lakes, an eminent question popped up. What if the best features of both could be combined to clear the bottlenecks? As with any new technological innovation, drive for efficiency, and getting the best of those available, data lakehouses came into the picture.

Data Lakehouse (2017) supersedes data warehouses in the department of storing raw, structured, and unstructured data—a major shift from the traditional rigidity of only structured data finding its way into data warehouses. Data Lakehouses with a CAGR of 22.9%, add a lot of flexibility in terms of data types and hence solve the rigidity that comes with data warehouses. Additionally, data lakehouse came up as a low-cost option that combined the exceptional querying and performance-optimized features of the data warehouse and the flexibility of data flakes.

Data Lakehouse has emerged as the preferred mode, as it eliminates the need for maintaining separate systems for raw data storage and analytics, thus reducing cost and complexity, and adding ease and cost-effectiveness for the organization. This shift is due to the potential that data lakehouse demonstrates in terms of the power of unified data management with ACID transactions and real-time data processing, upending the way businesses approach big data analytics.

“Lakehouses redeem the failures of some data lakes. That’s how we got here. People couldn’t get value from the lake”
 Adam Rosenthal, vice president and analyst at Gartner  (Source)

For instance, an organization in the retail segment that needs sales forecasting or customer sentiment analysis can easily integrate structured point-of-sale data with unstructured social media feeds—WITHOUT moving data between systems!

Or a financial firm can store tons of historical trading data and use real-time queries for risk modeling and can gain hugely from both the scalable storage and rapid analysis that Data Lakehouses offer.

Data Lakehouse: The Future of Unified Data Architecture

Data Lakehouse: The Future of Unified Data Architecture

Data Lakehouses are the best thing to happen for organizations that have a disparate enterprise data warehouse architecture diagram where data has to be duplicated in separate lakes and warehouses.

The high-performance analytical capabilities of data lakehouses that are optimized for SQL-like queries on massive datasets are a complete winner and the flexibility offered for different types of data in one system stands as a major advantage.

The cherry on the cake is the lower Total Cost of Ownership (TCO) because fewer systems mean fewer maintenance needs, negligible chances of data duplication, and an ecosystem with simplified data governance. No wonder that it is adopted by top companies across tech and finance, including Netflix and Goldman Sachs.

Frequently Asked Questions

The assumptions about Databricks being a data warehouse or data lake are incorrect, rather it is a data platform built on the Lakehouse architecture. Its uniqueness lies in the dual features of scalability, flexibility—a feature of a data lake, and reliability and performance— a feature associated with a data warehouse.

Yes, they do and how you prioritize agility vs. performance in your data usage is what determines which one is to be used. Data strategy-wise a data lake adopts a schema-on-read approach, storing raw, unprocessed data for future flexibility, whereas a data warehouse uses a schema-on-write strategy, focusing on structured, pre-processed data optimized for fast, query-driven insights. The difference? WHEN and HOW data is structured, thus impacting governance, speed, and use cases.

Data Lakehouses are surely being touted as the next big thing in data architecture but they are more likely to augment or evolve from data warehouses rather than completely replace them. Data Lakehouses are a convergence point and are slowly blurring the boundaries, and bridging the gap by providing real-time analytics, ACID transactions, and a unified platform for both structured and unstructured data, which traditional data warehouses lack.

Some modern Data Lakehouses, like the one built with Databricks’ Delta Lake, can achieve up to 10x faster query performance when compared to traditional data lakes.

Absolutely. For small businesses with structured data in the range limited to terabytes data warehouses are the right fit which can transition to a data lake if unstructured data starts growing, while data lakehouses are ideal for large enterprises that handle petabytes or more of data.
