What is big data?

Big Data is confusing for new engineers. You are using it, for example, goolge search engine. When you want to search for what you want, you don't know what the backend architecture is, nor how it processes massive petabytes of data. You don't need to know this, if the data does not have a large-scale distributed computing cluster, you can imagine how long it takes to obtain a record from Pb-level data.

In short, there are two types of big data:One typeIt crawls public information from the Internet and records it on the Indexing Server to quickly retrieve the data you need. For example, I want to know what is the most discussed in an industry and which websites have illegal information, to change marketing methods.AnotherIt is distributed processing of massive data and rapid mining of valuable information, such as some aspects of Baidu application logs, want to know which regions have high access traffic and historical trends, etc., through distributed cluster processing, you can visualize the results in a few seconds.

In the modern Internet, data is growing. In the past, data has become a hot topic! It is also a technology worth our attention.
