Emerging data management trends to watch in 2021

Facts administration is a critically essential foundation for enabling purposes, analytics, enterprise intelligence and equipment finding out.

Over the class of 2020, a variety of critical tendencies emerged as knowledge administration sellers and consumers alike were affected by the world-wide coronavirus pandemic and the require to speed up knowledge insights value correctly.

Among the the crystal clear tendencies that have emerged is the require for businesses to make far better use of cloud storage to permit knowledge lakes that are additional than just knowledge swamps. Multiple sellers and open supply initiatives took up the obstacle of optimizing knowledge lakes in 2020, with distinct knowledge lake engines and query systems.

2021: Lakehouses and Iceberg on the horizon

Yet another critical knowledge administration craze in 2020 was the idea of the knowledge lakehouse. The knowledge lakehouse is a specialized architecture that combines the finest features of knowledge lake and knowledge warehouse models.

The lakehouse idea was pioneered by Databricks in 2019 with the vendor’s open supply Delta Lake undertaking. In 2020, the lakehouse idea grew to become commercially out there with the San Francisco-dependent vendor’s Delta Motor know-how launched in June and even further expanded in the Databricks Unified Facts Analytics Platform released in November.

“Databricks has very long been regarded for supporting knowledge science workloads, but it stepped up on the enterprise intelligence and knowledge warehousing aspect in 2020 with its lakehouse,” commented Doug Henschen, an analyst at Constellation Investigate.

Henschen extra that it truly is no very simple make a difference assembly mission-significant desires for enterprise intelligence and analytics at scale. While Databricks likes to tout query speed overall performance stats, in Henschen’s look at that is just 50 percent the tale. For 2021, he is on the lookout to see how Databricks’ know-how is adopted by customers with substantial concurrency among the consumers and queries.

While the lakehouse idea has its set of adherents, with Databricks and the open supply delta lake undertaking, a rival work emerged in 2020 that is set to have a big yr in 2021. That is the open supply Apache Iceberg undertaking, at first developed at streaming media huge Netflix.

Among the critical knowledge administration tendencies in 2020 was the idea of the knowledge lakehouse.

“Iceberg is actually an open table format for massive analytic knowledge sets,” spelled out Daniel Months, engineering supervisor for big knowledge compute at Netflix, at the Subsurface digital meeting in July. “It really is an open neighborhood regular with a specification to guarantee compatibility throughout languages and implementations.”

Beyond Netflix, both equally Apple and Expedia are early consumers of Iceberg, which is positioned to split out for broader adoption in 2021. To this level, Iceberg has been an open supply neighborhood work, but that will adjust in 2021 as organization-supported instruments arise. The earliest commercially supported system that will integrate Iceberg is likely to be from Dremio, a knowledge lake engine vendor dependent in Santa Clara, Calif.

Dremio was fast paced in 2020 creating out its system that permits consumers to query knowledge lakes in an optimized process for enterprise intelligence and analytics.

Dremio has been an lively participant and contributor in the open supply Iceberg undertaking and is the host of the Subsurface meeting. In 2021, the company ideas on integrating Iceberg into its system, which will present an option method to the Databricks lakehouse method.

No matter whether an Iceberg-dependent approach to permit much easier knowledge administration in a knowledge lake will be more rapidly or additional economical than a lakehouse design remains to be seen, but it will be a critical craze to observe in 2021.

Spark vs. Presto

Yet another emerging craze for knowledge administration in 2021 will be in the knowledge query sector.

The open supply Apache Spark query engine experienced a key release in 2020 with it 3. milestone that grew to become typically out there on June 18. Spark 3. launched the Adaptive Query Execution (AQE) element to speed up knowledge queries.

Tough Spark in 2020 was the open supply Presto undertaking that acquired the assist of multiple business sellers all vying to take workload share from Spark.

Among the the sellers that emerged in 2020 with Presto is Starburst, which lifted $42 million in funding on June 16. The firm’s core system is Starburst Company Presto, which was updated in July 2020 with capabilities to assist knowledge queries on Hadoop workloads and cloud knowledge lakes.

Yet another vendor that emerged in 2020 to convey Presto to enterprises is Ahana, which lifted $4.8 million in seed funding on Sept. 22. Together with the financing, the company launched its Ahana Cloud for Presto process, supplying a managed assistance for businesses working with Presto.

Incorporating even further momentum to the escalating use of Presto, on Dec. 8 the Varada Facts Platform grew to become typically out there. Varada’s knowledge virtualization system embeds Presto as the engine that will help to permit knowledge queries from disparate resources of knowledge.

Presto is not likely heading to displace Spark as the dominant SQL query engine in 2021, but it will undoubtedly bring in new consumers and sellers as enterprises request to improve knowledge administration queries.

Personal knowledge administration in 2021

While enabling businesses to additional correctly use knowledge is a critical craze for 2021, so too is the require for enhanced personalized knowledge administration.

Company System Group (ESG) analyst Mike Leone pointed out that the sector for personalized knowledge administration is designed up of a selection of sellers, like new entrants these as Dataswift and Inrupt that are centered on enabling stop consumers to command their possess personalized knowledge.

“I consider all through this yr, we will see stop consumers demand from customers additional command of their possess knowledge and we will see governing bodies step up their activity to address stop-consumer knowledge privateness problems,” Leone explained.
