The Magento 2 core has an excellent logging system: Every time that a customer logs in or out, his/her details are logged. This might lead to a big database size over time. Not everybody wants this: There are
numerous threads discussing the periodic cleaning of those tables using the SQL statement TRUNCATE. But this is only part of the problem.
Besides filling up the database, this logging also causes various extra SQL INSERT statements to be made for every pageload. If you have a busy site, this certainly has an impact on database-performance.
Now, if you're relying on those Magento 2 log statistics, you'll just have to accept this as a fact. However, if you're using other external services like Piwik or GoogleAnalytics, this Magento logging is actually an unwanted feature.
Our extension gives you the power to disable all this Magento 2 logging: Either for all requests being made, or only for search-robots. It disables logging, but also disables the autoincrement flag for certain search patterns: The latter is interesting if you are interested in what your real-life customers are actually searching for, while by default search engines mess up these statistics.
This extension makes use of interceptors (aka plugins) to override various Magento 2 core classes. See the etc/di.xml file for details.
