The data center is becoming the "information power plant" of the new era and becoming the infrastructure of knowledge economy. Over the past year, "Big Data" is becoming a hot topic. The development of information technology in half a century mainly solves the storage, processing and application of "structural" data in cloud computing. The characteristics of "structural" data are like you go to the bank to access money, the bank's computer system records your name, after the name is your access to the amount of money, time, type and other information. These data are characterized by "strong logic" and each "cause" has "fruit". However, in real society, a lot of data is actually not "obvious ..."

Now Apache Hadoop has become the driving force behind the development of the big data industry. Techniques such as hive and pig are often mentioned, but they all have functions and why they need strange names (such as Oozie,zookeeper, Flume). Hadoop has brought in cheap processing of large data (large data volumes are usually 10-100GB or more, with a variety of data types, including structured, unstructured, etc.) capabilities. But what's the difference? Today's enterprise Data Warehouse ...

Editor's note: Jay Kreps, a chief engineer from LinkedIn, says that logs exist almost at the time of the computer's creation, and there is a wide range of uses in addition to distributed computing or abstract distributed computing models. In this paper, he describes the principles of the log and the use of the log as a separate service to achieve data integration, real-time data processing and distributed system design. Article content is very dry, worth learning. Here's the original: I joined the LinkedIn company at an exciting time six years ago. From that time ...
