Data lakes can’t rename columns? Queries might just give wrong answers? Partitioning is a manual process that people mess up all the time? Sigh. If you’re looking at Iceberg from a data lake background, its features are impressive: queries can time travel, transactions are safe so queries never lie, partitioning (data layout) is automatic and can be updated, schema evolution is reliable - no more zombie data! - and a lot more. At Netflix, we used Iceberg to transform our data lake into a cloud-native data warehouse, by building the guarantees of SQL into data lake tables. What is Iceberg?Īpache Iceberg is a modern table format for analytic tables, created by my team at Netflix and later adopted at companies like Apple, LinkedIn, Stripe, Airbnb, Pinterest, and Expedia. Those are radical changes! In this post, I’ll take a deeper look at what Iceberg is and why it is being built into the foundation of the modern data stack. A little earlier this year, Google announced BigLake, a project that will bring together BigQuery and open standards, like Iceberg and Parquet. Last month, Snowflake announced upcoming support for native Iceberg tables. The future of the modern data stack is tightly coupled to how those warehouses evolve - and that’s where Iceberg comes in. The transition from ETL to ELT led by Fivetran was one of several trends that converged to make the modern data stack possible, but the initial spark was the arrival of cloud data warehouses: Snowflake and BigQuery. For example, Fivetran makes it easier than ever to load all of your data sources into your data warehouse, immediately ready for consumption or transformation. The modern data stack has proven to be incredibly valuable. Visit more terms and definitions.This article is guest authored by Ryan Blue, one of Iceberg’s creators.

It also protects those who simply value their privacy and aren’t doing anything illegal but don’t want their browsing habits tracked. Facebook recently established a direct connection to Tor, allowing users in these areas anonymous access to their site. Some governments censor the Surface Web, blocking certain web sites and monitoring their citizens’ online activities. The software was developed by the United States government to protect whistleblowers, dissidents who live under repressive political regimes and others who would be in danger if their identities were compromised. Like the Deep Web itself, Tor does have legitimate uses. This makes Tor users much more difficult to track online. It also anonymizes users by bouncing their web traffic through a randomized series of encrypted servers located around the world. So if the Deep Web isn’t indexed by normal search engines, how do users navigate it? The answer lies in browser software called The Onion Router, or Tor for short. The Deep Web contains pages where criminals use a type of digital currency called Bitcoin to trade and sell everything from stolen credit card numbers to illegal drugs. Unfortunately, cyber criminals also use the Deep Web for communication and to hide their illicit activities. Aerospace engineers could find data on how to build safer airplanes. Doctors could access information currently hidden in archived databases about new research and medical procedures. The information locked away in the Deep Web is valuable. Collectively these resources hidden from search engines are called the Deep Web. Subpages on public web servers that are not linked to other pages do not show up in search results, but if someone knows the page URL they can access the page directly by typing it into their browser’s address bar. Hidden pages include unpublished blog posts, forums that force users to log in before they can view the contents and news sites that archive their stories for paid subscribers only after a specific amount of time. While the web is growing constantly, cybersecurity experts know the vast majority of web pages are inaccessible to search engines. These publically viewable pages are part of the Surface Web, but they’re just the tip of an iceberg. Modern search engines like Google, Yahoo and Bing use programs called spiders that crawl the web and find links between the main page on a site and its linked subpages. The development of automated search engines made it much easier for users to find information. It was cumbersome and links were often outdated. In the early days of the web there were no search engines, and people relied on finding information using pages with long lists of HTML links. The World Wide Web is a vast and always changing network of web pages.
