Multi-threaded parser

Data processing in manual mode is completely unproductive. Digital data on the Internet must be processed digitally, this saves a lot of resources and improves results. For such tasks, special programs are used – parsers.

They serve to collect and process information of all sorts: prices, goods, reviews, auction lots, real estate offers. In the case of parsing really large sites with large amounts of data, parsing with regular parsers can take a significant amount of time – hours and days.

At the same time, all the resources of your machine are not used, since during normal parsing, the process occurs sequentially:

• The PHP script requests the page you are looking for;
• followed by waiting for a response from her
• after which the parser receives and processes the data;
• and the whole cycle is repeated again.

The main resources of your computer are not used, even if they are not occupied by other processes. Therefore, a regular parser is suitable for collecting small amounts of information. And for large amounts of data, a multithreaded parser is used. It runs several PHP scripts at the same time, each of which can parse its own page of the same resource. In the case of using such a multi-threaded parser, the process speed increases tens and hundreds of times. A multithreaded parser can be written in another language – AVADA MEDIA uses C ++, Ruby, Go and even JavaScript with the Node.js framework for this. The specific choice is based on the tasks that the multithreaded parser will perform. These tasks can be:

• collection of reference bases for a variety of tasks;
• assessment of sites and domains according to the specified parameters;

• monitoring the resource and all its pages according to the place occupied by it in the search;
• in fact, the collection of context – it can be not only text or pictures, but also videos;
• backlink tracking;
• collection of information in certain categories: phones, email addresses, messages with a given topic and keywords, announcements;
• collecting and evaluating keywords for SEO needs;
• and many other purposes.

A multi-threaded parser is widely used for the purpose of ensuring the safety of the resource. for example, to collect or filter linkbases based on cyber threats. Network administrators can use a multithreaded parser to work with whois services: determining registration dates and the end of registration of domain names.

The possibilities of a multi-threaded parser are enormous. This is the ability to conduct parallel parsing of up to 10 thousand threads, depending on the task and the type of data, optimization of complex operations, the inherent ability to scale the resource from the very beginning.

The parser can work both on a server running Linux or FreeBSD, and on a user’s personal computer running Windows.

The AVADA MEDIA company develops multi-threaded parsers taking into account the client’s tasks, the project initially includes the possibility of further development and scaling. Also, the parser is created taking into account the possibility of automatic work without user intervention for a long time.
