Caching in Rails is easy since the framework has some built-in functionality for this action. Developers do not have to look for 3rd party applications to efficiently cache their applications.
Although a 3rd party caching tool is still a possibility, understanding cache in rails will deem the 3rd party applications unnecessary. After years of updating, Rails have included great caching tools for ease of development.
For additional security, Rails have added sweepers for its cache. A sweeper for cache is practically a tool that will completely remove all cached data in on simple command. Developers could set a time or date when the cached data will be completely removed.
Sweepers could also be used as an observer for data changes. When properly implemented, sweepers could monitor the changes in the application. If new data is sensed, the sweeper could be configured to automatically delete the previous information.
This is very useful especially when you have an online application that continuously processes data. Through sweepers, the expected data will be loaded faster as it has deleted the previous information and concentrated on the new data.
This form of caching is specifically geared towards the database of the application. This form of caching is also built-in on Rails so compatibility with SQL is no problem at all.
SQL caching records all queries which could be easily loaded again when the user needs them. Like most caching tools, expiration could also be implemented at the developer’s preference.
Rails also enable developers to specify how the cached data will be stored. This gives the developers a freedom on how fast (or slow) their data could be recorded and implemented.
