Data Lakehouse architecture offers an effective solution to these diversified data and aggregation requirements through a spectrum of inbuilt functionalities and highly optimized query engines, directly on open data formats, enabling flexibility and agility. The data architecture is expected to be centralized, agile, and cost-efficient for heavier workloads and data volumes to empower a broad group of stakeholders-operational, regulatory, compliance analytics (profit and loss, claims, International Financial Reporting Standards, etc.), Data science and power users (back-office analytics, customer churn, segregation, underwriting risk management, etc.). End users require access to governed, cataloged, yet not highly standardized data, a historical lineage with minimal data latency. Generally, health care or insurance companies process large volumes and a variety of data from internal and external applications to effectively predict risk and optimize costs. Real-world application of Lakehouse architecture These technologies allow to simultaneously cater to business intelligence and data scientists with dynamic data frame capabilities with unconstrained access to data.ĭata Lakehouse architecture drastically reduces the need for large-scale complex data pipelines to curate and standardize data-allowing a single centralized layer for all reporting, analytical and Artificial Intelligence/Machine Learning (AI/ML) needs. Technologies adopting this paradigm enable custom capabilities, including but not limited to effectively achieving governance, time travel, lineage, and support for ACID (Atomicity, Consistency, Isolation, and Durability) properties. Rapid developments in Compute and Cloud have provided an opportunity for a new data architecture paradigm, allowing transactional data processing capabilities (including structured query languages) directly on large volumes of raw data in their native and diverse formats i.e., sourcing layer compared to curated or consumption layers or limiting noise data (unwanted data) without heavy data workloads (for instance, Extraction Transformation Loading).

Time for realization, as Data Lake accepts datasets in raw formats and must undergo a series of transformations to establish any meaningful and structured relation in the data.The key constraints while using a combination of Data Lake and Data Warehousing to note are:
It is imperative to swiftly eliminate delays and noise in the data early in the architecture, avoiding cost overheads and inefficiencies. In the current Age of With, where enterprises are focused on monetizing data and insights to their best advantage-the speed and agility of provisioning new data for decision-making are paramount. They consolidate all sources of data in a Data Lake and later develop heavy pipelines to transform only the required data to their respective Data Warehouses or Data Marts. So, enterprises tend to maintain both versions- Data Lakes and Data Warehouses. While it addressed many challenges related to data ingestion and storage, it often caused serious bottlenecks for consumption, including limited capabilities with transaction query engines, aggregation without heavy data workloads, as well as difficulties in establishing relationship between datasets. Data Lake allowed massive storage layers at the forefront with no schema enforcements or minimal standardization. With the demand for end-user self-sufficiency, reducing latency, soaring storage costs, and the advent of streaming data-the need for a storage layer that can accept data in a variety of formats at lesser cost created an opportunity for Data Lake architecture. They are cleansed, standardized, and enabled data for specifically targeted analytics.
In this regard, specialists from Data Architect teams at Deloitte explore how storage architecture, namely Data Lakehouse, enable an integrated, agile and cost-effective approach to data management for enterprises.ĭata Warehouses have been the answer to all enterprise business intelligence needs for decades. With the ever-increasing data needs of multiple stakeholders and consumers in an enterprise, we see that data architectures are evolving significantly to meet the rising demand.
