On Aug 5, 2022, the CEO of Databricks announced Friday that his company has surpassed $1 billion in annualized revenue. This is more than double the $350 million in annualized revenue it reported just two years ago. This clearly rivals Snowflake’s growth and paves way for Databricks’ much-anticipated IPO in the near future.

Data is more expensive than oil. However, while data is an asset, lack of a unified data strategy can be a bottleneck, a huge cost to business and can lead to competitive disadvantages. According to some estimates in 2022, we generate a total of 2.5 quintillion bytes (2.5 e+9 GB) of data every single day. Most companies, especially large and mid-size companies have data silos that separate data engineering, analytics, BI, data science, and machine learning. The data strategy can be quite complex. It's common to see multiple data sources and duplication of data, not just in the same data store but also in multiple data sources within the same organization. Imagine a Fortune 500 that has acquired companies with different  technology stacks and polyglot persistence.

The model can incorporate the latest data, despite being trained on a small dataset. Learn more...

We live in a world in which we need real time actions, not just analysis. We need to be able to allow the AI based models to intelligently offer an experience that users are looking for in real time. In order for that to happen, traditional silos do not work. It’s too slow and complex. Databricks Lakehouse Platform solves that problem.

What is a data warehouse?

Data warehouse

Before the advent of NoSQL databases, most data solutions were structured around RDBMSs (Relational Database Management System). They were great for structured data. Data warehouses used to import data from RDBMSs and were used to help in decision support and business intelligence applications. So, data warehouses were great for structured data. With the advent of phones, tables and IoT devices, modern enterprises must deal with enormous amounts of data: structured, semi-structured and unstructured. On top of that, they must deal with variable data, high velocity and volume. Data warehouses, even though adapted their architecture gradually, were not suited for such use cases. In some cases, they could be used to solve the problem, but at an elevated cost.

What is a data lake?

Given the limitations of data warehouses, architects envisioned a single data solution to gather company-wide data. Imagine a company with different workloads of data: structure, semi-structured and unstructured in different data sources. All that data would be now moved to a data lake, which is a single repository of data in multiple formats. However, some of the challenges were:

  • Lack of enforcement of data quality standards.
  • Lack of transaction support.
  • Lack of unification of streaming, batching and traditional reads.
Data lake

Artificial intelligence has made recent advances in processing unstructured data: audio, video, image and text. To solve this problem, gradually companies ended up with a bunch of systems: data warehouses, data lakes, and specialized systems (streaming, time-series, graph, and image databases). This makes the data strategy of a company highly inefficient, introduces delays, increases room for error and reduces competitiveness.

Databricks Data Lakehouse

Databricks Data Lakehouse

There has been an ever-increasing need for a flexible, high-performance data system that includes analytics, real-time monitoring, data science, and machine learning. The data lakehouse architecture was created after understanding the current and future needs of the enterprise. It’s an attempt to address the limitations of data lakes. A data lakehouse is a new, open architecture that not just combines the best elements of data lakes and data warehouses but also addresses more use cases and fixes the underlying challenges. Data lakehouses redesigns data warehouses for the modern world. It uses similar data structures and data management features directly on top of low-cost cloud storage in open formats.

Key features of Databricks Data Lakehouse:

  • ACID support: It’s very common in the enterprise to have multiple APIs and applications constantly reading and writing data. Multiple parties can concurrently modify the same set of data. In order to ensure consistency, transaction support is essential. Data lakehouse guarantees ACID (Atomicity, Consistency, Identity, and Durability) transactions.
  • Snowflake/star schema support: It supports enforcement of schema and its evolution. This involves supporting star or snowflake schema architectures.  The Delta Lake transaction log serves as the single source of truth. It’s like a central repository that tracks all changes made to the table. During new reads Apache Spark checks the transaction log to see if any changes were made and makes the required updates to the table. Hence, the single source of truth is enforced, and the user’s version of a table is always synchronized to it.
  • Governance and compliance: Delta Lake is the default storage format for all operations on Databricks. It’s an optimized storage layer that provides the foundation for storing data and tables in the Databricks Lakehouse Platform. It uses mutual exclusion to serialize commits properly. In case of an event, a commit is retired silently. It uses optimistic concurrency; a very common technique used to allow multiple concurrent reads and writes while tables change. This log is a single source of truth and serves as a database level audit table. This transaction log offers a verifiable data lineage. This serves as the pillar of strong governance, audit and compliance needs in the enterprise.
  • Business Intelligence: Traditionally, the RDBMS used to be the single source of truth and data warehouses were built on a copy of data from the RDBMS. This introduces latency, staleness and increases the cost of operating with two sources of data instead of one. The introduced complexity increases room for error. This is solved in a lakehouse environment because the business intelligence tools can now be run on the source data itself.
  • All types of data: Traditionally, it was very common to use an RDBMS for structured data, denormalize the data into a data warehouse, and use appropriate data stores for images, text, audio and video. This led to the introduction of multiple data stores which increased latency and overall complexity. Lakehouse is one repository for all kinds of data: structured, unstructured and semi-structured data.
  • Open principles: Databricks can read and write data directly to and from formats such as Parquet, CSV, JSON, XML, Snowflake, Azure Synapse, Amazon S3, Google Big Query etc. Apache Spark is open source and is compatible with standard open source solutions. Databricks provides APIs so users can access the data directly from a wide variety of tools, frameworks and engines.
  • Complete data ecosystem support: The platform supports all modern data workloads including machine learning, data science, data streaming,  SQL and data analytics. All these tools are supported on the same data repository. Enterprise is full of use cases which require real-time streaming needs to generate real-time support. Traditionally, there used to be a need for dedicated systems other than the main system to support real-time data applications. Now that need has been eliminated as the platform supports streaming on the common data repository.

Machine Learning

Machine learning is a very innovative field and is very disruptive. However, ML lifecycle is still very new compared to SDLC (Software Development Lifecycle). MLOps (Machine Learning Operations) is to ML what DevOps (Development and IT operations) is to SDLC. Building models and creating pipelines that seamlessly deploy the models into production is quite complex. According to multiple estimates in 2022, more than 60% of models do not make it to production. ML requires working with unstructured data, but we still have the same versioning and governance needs for that data as we have for structured data.

Machine learning pipeline

Databricks supports all major ML platforms and technologies. Data scientists and engineers can use R and Python to access the data. MLflow, an open-source platform developed by Databricks, automates the end-to-end ML lifecycle and has become a leader in simplifying the process of standardizing MLOps and deploying the ML models to production. The ML lifecycle can be very complex depending on the underlying business problem we are trying to solve. We need to version different models along with related code, dependencies, visualizations and intermediate data. This is required to be able to track what’s the current state of the deployment, what exactly needs to be redeployed and where, and in order to rollback updated models in appropriate cases.

Databricks MLflow Tracking

Data lakehouse makes machine learning and data science data-native, which enables us to perform everything from exploratory data analysis, model training and model serving exactly where the rest of the data is being managed. It has everything you need for a team to collaborate and is designed keeping in mind the different personas: data engineer, data scientist, ML engineer, business stakeholder and data governance officer.

Keynote: Best practices on UI, API and Server-side

In our recent keynotes delivered in five continents world-wide we have demonstrated how we can scale the current applications with high performance and at a fraction of the current cost using modern technologies and architecture. The main highlights of this keynote were:

  • Scalability best practices
  • API best practices
  • UI best practices
Keynote: Best practices on UI, API and Server-side

In scalability best practices, the pros and cons of all major database architectures were discussed. The discussions included CAP Theorem, whitepapers on scalability, different types of NoSQL databases along with their use cases, polyglot persistence, scalability bottlenecks and how to avoid them. Finally, the best principles for an auto-scale architecture were discussed. Quite interestingly, the highly scalable architecture was also quite inexpensive to create as well as maintain.
