90% of big data is machine data. In addition to traditional IT data from servers, storage, and networks, a large amount of unstructured data from the mobile Internet and IOT are also machine data. Compared with database data, machine big data features a large volume, fast growth, high complexity, and diversity, but its value density is slightly lower.
Splunk is a company dedicated to processing machine data. Since becoming the first public company in

Let's talk about how to use Python to implement a big data search engine.
Search is a common requirement in the big data field. Splunk and ELK are leaders in non-open source and open source fields respectively. This article uses a small number of Python code to implement a basic data search function, trying to let everyone understand the basic principles of big data search.

The first step is to implement a bloom filter.

Hunk/Hadoop: Best Performance practices
Whether or not Hunk is used, there are many ways to run Hadoop that cause occasional performance. Most of the time, people add more hardware to solve the problem, but sometimes the problem can be solved simply by changing the file name.Run the Map-Reduce task [Hunk]
Hunk runs on Hadoop, but this does not necessarily mean effective use. If Hunk runs in "complex mode" instead of "intelligent mode", it will not actually use Map-Reduce. Instead, it will direct
In daily life, we know that search engines such as Baidu, 360, Sogou, Google, and so on, search is the big data in the field of common needs. Splunk and elk are leaders in the field of non-open source and open source, respectively. This article uses very few Python code to implement a basic data search function, trying to get everyone to understand the basic principle of big data search.Bron Filter (Bloomfilter)The first step is to implement a fabric
