Caching will slow performance of the read queries because the cache is updated when the cache cannot find the requested data.

<h3>What is RDS?</h3>

A distributed relational database service provided by Amazon Web Services is known as Amazon Relational Database Service (or Amazon RDS) (AWS).  It is a "cloud-based" web service created to make it easier to set up, manage, and scale a relational database for use in applications. Automatic management is used for administration tasks including patching the database software, backing up databases, and enabling point-in-time recovery. A single API call to the AWS control plane on demand can scale storage and compute resources. As part of the managed service, AWS does not provide an SSH connection to the underlying virtual machine. The AWS Management Console or the Amazon Cloud Watch API both provide performance data for Amazon RDS.

Why might you need to convert a file to another file type
Alex17521 [72]
This depends on what program you're using. Some programs can only read certain files exclusive to that program, such as .psd files can usually only be read in Photoshop or other adobe programs. Many fields of work (Journalism, the Arts, Design, etc.) ask for .psd files to be converted to either .png, .jpg, or .tiff so that it can be seen on many other platforms.

For images especially, files are more compatible either on a program or printed. for example, .png files are good for storing color data from computer to computer, but if you print a .png file, the quality is poor. hence it's recommended to save files you want to print for designs as .jpeg, because .jpeg can more easily be printed and will then be presented at a high quality.

Sometimes color quality changes depending on CMYK as well but that's a whole other ball of wax.
