Data pipeline
The efficient flow of data from one location to the other is one of the most critical operations in today’s data-driven enterprise.
Indeed, data flow can be precarious due to the variety of things that can go wrong during the transportation from one system to another :
In this sense, by eliminating many manual steps from the process, data pipelines enables a smooth, automated flow of data from one station to the next.
But what is a data pipeline ?
A data pipeline automates the processes involved in extracting, transforming, combining, validating and loading data for further analysis and visualization. Furthermore, it can process multiple
data streams at once and provides end-to-end velocity by eliminating errors and combatting bottlenecks or latency.
In short it is an absolute necessity for today’s data-driven enterprise.
Also one of the advantages of a data pipeline rely in the fact that it views all data as streaming data and allows for flexible schemas. Indeed, regardless of whether it comes from a static
sources (like a flat-file database) or from real-time sources (such as online retail transactions), data pipeline divide each data stream into smaller chunks that it process in parallel on
order to confer extra computing power.
How is data pipeline different from ETL ?
ETL stands for Extract, Transform and Load. ETL systems extract data from one system, transform the data and load the data into a database or data warehouse. Legacy ETL pipelines typically run in
batches, meaning that the data is moved in one large chunk at a specific time to the target system. Typically, this occurs in regular schedule d intervals; for example, you might configure the
batches to run at 12 a.m. every day when the traffic is low.
By contrast “data pipeline is a broader term that encompasses the ETL as a subset. It refers to a system for moving data from one system to another. The data may or may not be transformed, and it
may be processed in real time instead of batches.
Who needs a data pipeline ?
While a data pipeline is not a necessity for every business, this technology is especially helpful for those that :
