There is significantly desire in cloud data lakes, an evolving engineering that can permit corporations to improved deal with and analyze data.
At the Subsurface digital conference on July 30, sponsored by data lake engine seller Dremio, corporations together with Netflix and Exelon Utilities, outlined the technologies and strategies they are employing to get the most out of the data lake architecture.
The fundamental guarantee of the modern day cloud data lake is that it can separate the compute from storage, as nicely as support to avert the threat of lock-in from any a single vendor’s monolithic data warehouse stack.
In the opening keynote, Dremio CEO Billy Bosworth mentioned that, although there is a large amount of hype and desire in data lakes, the intent of the conference was to glimpse beneath the floor — that’s why the conference’s identify.
“What is actually actually important in this product is that the data itself receives unlocked and is absolutely free to be accessed by numerous various technologies, which implies you can pick finest of breed,” Bosworth mentioned. “No for a longer period are you forced into a single alternative that may well do a single matter actually nicely, but the relaxation is type of normal or subpar.”
Why Netflix established Apache Iceberg to permit a new data lake product
In a keynote, Daniel Weeks, engineering supervisor for Big Data Compute at Netflix, talked about how the streaming media seller has rethought its strategy to data in modern several years.
“Netflix is actually a incredibly data-pushed organization,” Weeks mentioned. “We use data to influence choices all over the business, all over the solution content — more and more, studio and productions — as nicely as numerous internal initiatives, together with A/B testing experimentation, as nicely as the genuine infrastructure that supports the system.”

Netflix has significantly of its data in Amazon Very simple Storage Service (S3) and had taken various ways in excess of the several years to permit data analytics and administration on major. In 2018, Netflix begun an internal exertion, identified as Iceberg, to consider to build a new overlay to make structure out of the S3 data. The streaming media giant contributed Iceberg to the open supply Apache Program Basis in 2019, the place it is less than active development.
“Iceberg is actually an open table format for big analytic data sets,” Weeks mentioned. “It truly is an open community conventional with a specification to make sure compatibility across languages and implementations.”
Iceberg is nonetheless in its early days, but past Netflix, it is by now locating adoption at other nicely-identified brands together with Apple and Expedia.
Not all data lakes are in the cloud, nevertheless
Even though significantly of the focus for data lakes is on the cloud, amid the technical consumer periods at the Subsurface conference was a single about an on-premises strategy.
Yannis Katsanos, head of consumer data science at Exelon Utilities, thorough in a session the on-premises data lake administration and data analytics strategy his organization usually takes.
Exelon Utilities is a single of the greatest electricity technology conglomerates in the globe, with 32,000 megawatts of complete electricity-building capability. The organization collects data from smart meters, as nicely as its electricity plants, to support advise business intelligence, preparing and standard functions. The utility draws on hundreds of various data sources for Exelon and its functions, Katsanos mentioned.
“Each and every working day I’m amazed to uncover out there is a new data supply,” he mentioned.
To permit its data analytics process, Exelon has a data integration layer that includes ingesting all the data sources into an Oracle Big Data Appliance, employing numerous technologies together with Apache Kafka to stream the data. Exelon is also employing Dremio’s Data Lake Motor engineering to permit structured queries on major of all the gathered data.
Even though Dremio is generally connected with cloud data lake deployments, Katsanos mentioned Dremio also has the flexibility to be installed on premises as nicely as in the cloud. Presently, Exelon is not employing the cloud for its data analytics workloads, though, Katsanos mentioned, it can be the course for the foreseeable future.
The evolution of data engineering to the data lake
The use of data lakes — on premises and in the cloud — to support make choices is currently being pushed by a selection of financial and technical factors. In a keynote session, Tomasz Tunguz, taking care of director at Redpoint Ventures and a board member of Dremio, outlined the critical tendencies that he sees driving the foreseeable future of data engineering initiatives.
Between them is a shift to determine data pipelines that permit corporations to shift data in a managed way. An additional critical development is the adoption of compute engines and conventional doc formats to permit users to query cloud data with out obtaining to shift it to a precise data warehouse. There is also an increasing developing landscape of various data products and solutions aimed at encouraging users derive perception from data, he extra.
“It truly is actually early in this 10 years of data engineering I experience as if we are six months into a 10-calendar year-extensive motion,” Tunguz mentioned. “We will need data engineers to weave collectively all of these various novel technologies into wonderful data tapestry.”
