How to Manage and Store Value in Odoo 16 PoS Cache
Odoo 16 POS (Point of Sale) uses a caching approach to store frequently used data in memory, which can significantly improve system efficiency. The following are some of the main advantages of storing values in the Odoo 16 POS cache:
- Faster Data Access: By caching data, the information can be retrieved quickly without the need to read from the database. This results in shorter access times, which in turn improves the overall speed and performance of the POS system.
- Reduces Database Load: By caching frequently accessed data, the load on the database can be reduced. Thus, a POS system can improve its scalability, and performance problems caused by concurrent access of multiple users can be avoided.
- Enhanced User Experience: With a responsive POS system and faster data access, the user experience can be improved. Faster transaction completion can increase customer satisfaction and potentially increase sales.
Overall, Odoo 16 POS can benefit a lot in terms of performance, scalability, and user experience by caching value. POS systems can utilize system resources more effectively by using caches to store data. It also helps reduce the hardware requirements required to run the system.
In Odoo 16, you can use the 'pos' object to store values in the POS (Point of Sale) cache. The 'pos' object provides several methods for managing the cache. Here are some examples of ways to cache values in a post using the 'pos' object.
1. To store a value in the POS cache:
2. We can retrieve the stored value from POS Cache using:
3. We can store values for customers using:
4. We can retrieve the stored value from the customer:
5. To store the value in the cache with the key :
this.pos.pos_cache.set('total_amount', amount);
6. To retrieve the stored value using the key:
7. To store value using the ‘cache’ object:
this.env.pos.cache.put(key, value);
}
The ‘setCacheValue’ method is used to call the ‘put’ method of the ‘cache’ object to set the value for the key.
8. To retrieve value using the ‘cache’ object:
Return this.env.pos.cache.get(key);
}
The ‘getCacheValue’ method calls the ‘get’ method of the ‘cache’ object to retrieve the value using the key.
The data kept in the POS cache is temporary and will be deleted when the POS session ends. If you want to store data permanently, you should need a server-side storage solution.
