![]() ![]() Apache Spark started in 2009 as a research project at UC Berkeley's AMPLab. The founders reveal more about this split in the recently published article, Why leaving Facebook/Meta was the best thing we could do for the Trino Community. What is interesting to know about Presto is that, due to some legal complications, its original founders were forced to branch off of Presto’s initial open-source project and develop what is now called Trino. Presto’s Connector API allows plugins to provide a high performance I/O interface to dozens of data sources, including Hadoop data warehouses, RDBMSs, NoSQL systems, and stream processing systems. Presto was developed at Facebook as an open-source distributed query engine which supports much of the SQL analytics workload at Facebook. It brings the reliability and simplicity of SQL tables to big data, while making it possible for engines like Spark, Trino, Flink, Presto, Hive and Impala, to safely work with the same tables, simultaneously. Iceberg is a high-performance format for huge analytic tables. Unlike Databricks and Snowflake which manage both computing and storage, there are newer solutions such as Apache Iceberg which are only storage. I have to include Apache Iceberg as solutions such as this are 100% pure storage. But they also tend to be the location we store data.Īpache Iceberg. The truth is tools like Snowflake and Databricks are both far more than storage. It is an open-source storage framework that provides support for ACID transactions, schema enforcement, time travel(meaning rollbacks and historical audit trails), and several other ever-expanding features. Databricks provides a data platform that combines several managed services, including Spark, Delta Lake, and MLflow.ĭelta Lake acts as the storage component for Databricks. The company itself was started back in 2013 by the original founders of Spark, the UC Berkeley professors Ali Ghodsi, Ion Stoica, and Matei Zaharia. That's because it was developed by the same people. Learn more about Snowflake in this video I made: Why everyone cares about Snowflake.ĭatabricks (Delta Lake) Databricks itself is very tightly coupled with Spark, which we cover in more depth later. Currently, depending on who you ask, Snowflake has 15% to 18% of the market. This change, coupled with the fact that Snowflake felt more like a traditional data warehouse, made it very popular. You don’t need to scale up or scale down data warehouses and your team can easily pick how much computing is required. The ability to separate computation and storage allows database software to increase: It also provided a very familiar standard data warehouse “feel.” This gave users the ability to quickly switch between small, medium, and large data warehouses. Snowflake was the first widely adopted cloud data platform which separated storage and computation. A few of the common data engineering tools Data Storage This being said, there are some specific tools you will need to learn if you start looking into data engineering. It goes without saying tools like GitHub, databases, baseline cloud services and also coding, are all needed for data engineers. When it comes to data engineering, there is no shortage of tools. Getting into data engineering as a software engineer.In the second and final part of the series, we cover: Why data engineering is becoming more important.To answer this question, I pulled in Benjamin Rogojan, who also goes by Seattle Data Guy, on his popular data engineering blog and YouTube channel. As a software engineer, why is it important, what’s worth knowing about this field, and could it be worth transitioning into this area? Q: I’m hearing more about data engineering.
