Data Lineage Definition: Data lineage refers to the data’s “line of descent.” In other words, it’s a record of how data got to a specific location and the intermediate steps and transformations that took place as it traveled through business systems. For organizations that depend on data, understanding where data comes from, evaluating its quality, […]
To make data available to data consumers like analysts for analytics and reporting, businesses need to aggregate data sources. Data virtualization and data lakes are popular approaches to breaking down data silos and providing centralized data access. Your approach can significantly impact scalability, cost, and performance, so it’s important to understand the differences. What Is […]
A data pipeline moves data between systems. Data pipelines involve a series of data processing steps to move data from source to target. These steps may involve copying data, moving it from an on-premises system to the cloud, standardizing it, joining it with other data sources, and more. Why Is a Data Pipeline Important? Businesses […]
Businesses produce a lot of data. Everything from customer feedback to sales performance and stock price influences how a company operates. But understanding what stories the data tells isn’t always easy or intuitive, which is why many businesses rely on data engineering. What Is Data Engineering? Data engineering is the process of designing and building […]
If your organization depends on data, you need a place to store it. Not only that — you need the right kind of data storage and management solution for the data you use and produce. Most organizations find that a data warehouse or data lake meets their needs. Many even use both. What Is a […]
Apache Parquet is an open source file format that stores data in columnar format (as opposed to row format). As a columnar data storage format, it offers several advantages over row-based formats for analytical workloads. Your choice of data format can have significant implications for query performance and cost, so it’s important to understand the […]
What Is a Data Lake? A data lake is a centralized repository that allows you to store all of your data, whether a little or a lot, in one place. Like a real lake, data lakes store large amounts of unrefined data coming from various streams and tributaries in its natural state. Also, like a […]
What Is a Data Warehouse? A data warehouse is a system used for storing and reporting on data. The data typically originates in multiple systems, then it is moved into the data warehouse for long-term storage and analysis. Data warehouses are on-premises or in the cloud. This storage is structured so users from many divisions […]
If you’ve ever discussed data warehousing, you’ve probably heard the term “ETL.” It refers to processes that allow businesses to access data, modify it, and store it. Organizations use ETL for a variety of reasons, including the efficient management of data and the ability to run business intelligence (BI) against their data. There are several […]
This week we announced a $135M series D at a billion-dollar valuation making Dremio one of the top funded companies in our space. Chief Product Officer, Tomer Shiran highlights our vision in this blog.
In this article, we will demonstrate how Kafka can be used to collect metrics on data lake storage like Amazon S3 from a web application.
What are Parallel Projects? Parallel projects are multi-tenant instances of Dremio where you get a service-like cluster experience with end-to-end lifecycle automation across deployment, configuration with best practices, and upgrades, all running in your own AWS account. Every time that you launch a new project, it comes with all the best practices already set up […]

This provides several benefits, including: In this article we walk you through the steps to provision and manage Elastic Engines, we […]
Introduction Enterprises often have a need to work with data stored in different places; because of the variety of data being produced and stored, it is almost impossible to use SQL to query all these data sources. These two things represent a great challenge for the data science and BI community. Prior to working on […]
Intro Amazon Web Services (AWS) is a cloud services platform with extensive functionality. AWS provides different opportunities and solutions for databases, storage, data management and analytics, computing, security, AI, etc. Among the offered databases and storages are Amazon Redshift and Amazon S3. Amazon Redshift belongs to the group of the leading data warehouses. It is […]
Introduction Modern businesses generate, store, and use huge amounts of data. Often, the data is stored in different data sources. Moreover, many data users are comfortable to interact with data using SQL while many data sources don’t support SQL. For example, you may have data inside a data lake or NoSQL database like MongoDB, or […]
Intro Forecasting air quality is a worthwhile investment on many different levels, not only to individuals but also communities in general, having an idea of what the quality of air will be at a certain point in time allows people to plan ahead, and as a result decreases the effects on health and costs associated […]
