Informations about the package laravel-database-cache
Database Query Cache
Requirements
- PHP 8.x
- Laravel 8.x / 9.x / 10.x / 11.x
Installation
You can install the package via composer:
Add the Eusonlito\DatabaseCache\CacheBuilderTrait
to your model:
Configuration
Add this variables to .env
file:
Default configuration values are set in config/database-cache.php
file:
Also you can set custom ttl
and key
on every ->cache(:ttl, :key)
call.
Usage
Just use the cache()
method to remember a Query result before the execution. That's it. The method automatically remembers the result for 3600 seconds.
If you are using the default config, this cache will be stored inside ['database', 'database|articles']
tags.
The next time you call the same query, the result will be retrieved from the cache instead of running the SQL statement in the database, even if the result is null
or false
.
The
cache()
will throw an error if you build a query instead of executing it.
Time-to-live
By default, queries are remembered by 60 seconds, but you're free to use any length, Datetime
, DateInterval
or Carbon instance.
Custom Cache Key
The auto-generated cache key is an BASE64-MD5 hash of the SQL query and its bindings, which avoids any collision with other queries while keeping the cache key short.
If you are using the default config, this cache will be stored inside ['database', 'database|articles']
tags with the key latest_articles
.
Operations are NOT commutative
Altering the Builder methods order will change the auto-generated cache key hash. Even if they are visually the same, the order of statements makes the hash completely different.
For example, given two similar queries in different parts of the application, these both will not share the same cached result:
To ensure you're hitting the same cache on similar queries, use a custom cache key. With this, all queries using the same key will share the same cached result:
This will allow you to even retrieve the data outside the query, by just asking directly to the cache.
Remember that you need to pass the same ordered list of tags to the tags
method as when cache was stored. Always use ['database', 'database|XXX']
when XXX
is the table name related with the query.
Tags
This package tag caches with two different tags (only supported by redis
and memcached
)
database
is the global for all database cache.database|XXXX
is the tag for every different table. Table name will be set with thefrom
string onQuery Builder
.
Flush caches
You can flush all database caches or only caches related with only one table:
