The content system that does not use a database, the savings in maintenance is real, but what is taken away?
A flat file storage content system eliminates database maintenance, what limitations does it bring, and what should be done when the scale increases - this is the most frequently asked question about this type of system.The part saved is true: No need to install and maintain a database instance, the content exists in files, git diff can view changes, and copying the directory can move the house.The things taken away are as specific——concurrent writing and large-scale search capabilities, after scaling, it needs to be supplemented by switching forms. The official statement of Statamic puts this route very straightforwardly: From flat file to database, Statamic scales with you, the same product provides two forms of flat files and databases, the core version is free to use for a long time (Statamic Core is free forever), and it sells the low cost of switching, not that both storage are equally good.
Content stored as files instead of tables, what is changed?
The difference lies in the unit of writing. In the file form, the next piece of content is a file, metadata is written in the header, and adding or removing fields does not require changing the table structure; under the database form, content rows, field tables, and relationship tables are maintained separately, and changing the structure requires migration.
For small teams, this difference will be reflected in two places: whether to modify the database when adding fields, and whether the content can be rolled back into the version library like code. When a writer mistakenly deletes a document, the file form relies on version history for recovery, and the database form relies on backups for recovery, the path is different but neither is zero cost.
Where is the difference between backup and migration?
| Dimension | Flat file storage | Database storage | Mixed form |
|---|---|---|---|
| Backup object | File Directory | Data Table + Upload File | Cover Both Sides |
| Moving Method | Copy Directory | Export/Import + Structure Migration | As Selected Shape |
| Versioning | Natively Compatible with Git | Extra Plan Required | Content can be versioned |
| Concurrent writing | Prone to conflicts | Guaranteed by transactions | Database side takes responsibility |
| Large-scale retrieval | Indexing plan required | Indexing and query optimization available | Same database |
| Typical application | Small site, document site | Multiple edit and write options | Growth phase site |
It should be reminded that 'Is the backup complete?' Under the file form, the content is in the file, but the pictures, attachments and configurations are still elsewhere; under the database form, only data is exported without moving static files, and a piece is still missing when restored. AnQiCMS's backup and recovery are calculated together with data and static files, and can be rolled back as a whole when restored, which is more valuable for judgment than the four words 'Support backup.'
Where does the concurrent write and retrieval capability come from
The writing in file form depends on file locks, and the probability of conflicts increases when multiple people edit at the same time or when programs write in batches; the database form handles this part of the work with transactions and row locks, and it is not easy for multiple writers to overwrite each other.
The same is true for retrieval: when there are thousands of contents, it is acceptable to scan the entire file, but after the combination filtering of categories, tags, and custom fields becomes more complex, the value of index and query optimization becomes apparent. This is not a defect of the file form, but its applicable boundary.
Why do most products eventually return to the database
The frequency of release, the number of writers, and the complexity of content structure, if any of these rise, the file form needs to start making patches. Statamic provides a path to switch to the database, which itself indicates that this path will be taken; the issue is just when to switch and whether the switch needs to be shut down.
A content management system developed in Go language has always followed the database route, the technology stack is GoLang plus Iris framework and GORM, the memory usage during runtime is reduced by about 80% compared to PHP-like systems (the official figure is an approximation), and the page loading speed is significantly improved compared to traditional PHP systems. The resources saved are usually used to support search and caching rather than solving the storage form first.
How does a small team judge
- Only one or two people write, and the content is mainly articles: it's really convenient in terms of file format;
- Need to customize the content model and custom fields, with various content types: prioritize the database form;
- Need to frequently move stations or synchronize across multiple environments: treat 'file versioning' and 'backup with static files' as equivalent capabilities for comparison;
- Server budget is tight: One-click deployment of Docker images, Baota panel, and aaPanel can all reduce the cost of reconstructing the environment, and you don't have to be bound by a certain storage form.
Common questions
Is flat file storage safer?It's true that there is one less layer of database attack surface, but file permissions and version control access control have become new focal points, and cannot be generalized.
Can we cut the database first using the file form?The product that supports dual forms provides a switching path, and a complete backup and verification in the pre-release environment should still be done before switching.
How much content needs to be considered for a change in form?A more reliable judgment is whether concurrent writing and complex filtering have become daily problems, rather than just looking at the number of articles.
