Symphony Next - Core Characteristics

A list of requirements for Symphony Next from differing user roles and perspectives.

Roles & Perspectives:

• Content publisher: User of the system. Front-line of the operation responsible for publishing/editing content on a regular basis. Isn't concerned with anything else other than what is required to do their job well.
• Content Manager: User of the system. Manages content publishers with more control of the overall system and more permissive user permissions.
• Website Builder (evaluating): Site developer/designer. Looking for a CMS/platform to use as the basis for their web work but needs to make a choice which will be a good fit for a number of projects of varying sizes for the foreseable future.
• Website Builder (building a system): Site developer/designer. Will most likely work primarily via the GUI in building the website but may or may not have other developent skills.

There are many types of caching that will improve website performance. Here are just five:

MySQL query caching

Every read query that Symphony executes is cached by MySQL. It is important to understand that this is not the result of the query, but the SQL statement itself. MySQL retains a pool of these statements so that they are quicker to execute in the future. This is pretty standard, and you can use it in your own applications too by using SELECT SQL_CACHE for your read queries.

Object caching

Once the database has been queried, the results are used to build objects (pages, data sources, sections, field, entries etc.). These objects are alive only for the lifespan of each page, and are destroyed at the end of each request. Systems such as Wordpress allow these objects to be cached and persisted between each page request (using APC, Memcache, flat files or MySQL), thereby shared between all users. Symphony doesn't do this, but it really should.

Fragment caching
