What Is Binary Data

Hadoop streaming is a multi-language programming tool provided by Hadoop that allows users to write mapper and reducer processing text data using their own programming languages such as Python, PHP, or C #. Hadoop streaming has some configuration parameters that can be used to support the processing of multiple-field text data and participate in the introduction and programming of Hadoop streaming, which can be referenced in my article: "Hadoop streaming programming instance". However, with the H ...

From an article in the Openmymind blog, the author introduces two MongoDB monitoring gadgets, Mongospy and Mongowatch, which they write with Node.js, and then puts forward the idea of using compression to save space when storing text in MongoDB. These two gadgets are not very powerful and simple to implement, and if you can manipulate MongoDB in any language, believe you can write a similar thing. Mongospy: A MongoDB slow query to monitor ...
