Product Merchandising Rule Caching Optimization for SuiteCommerce

Caching product merchandising rules significantly enhances performance by reducing the time new rules take to become active. By default, a new merchandising rule becomes active after approximately two hours. For businesses needing quicker updates, adjustments can be made within the DM_SS_Library.js file of the Product Merchandising bundle.

How to Adjust Caching Times

Caching for product merchandising rules is handled through the TTL = attribute, which is defined in two instances:

• The default setting is MAX_TTL, imposing a two-hour cache duration.
• To expedite the activation of merchandising rules, change both instances to MIN_TTL, effectively shortening the cache time to about five minutes.

Keep in mind that while reducing cache times can improve responsiveness, it may also impact overall system performance due to increased load.

Code Sample for Setting TTL

The following JavaScript function can be used to set the time-to-live (TTL) value for your caching rules:

1"text-purple-400">function setTTL(paramValue){
2       //ttl is not defined
3      "text-purple-400">if(paramValue == null || paramValue == undefined || paramValue == ''){
4         ttl = MAX_TTL;
5         "text-purple-400">return ttl;
6      }
7 
8      //ttl is defined but invalid
9      "text-purple-400">var paramValueInt = parseInt(paramValue);
10      "text-purple-400">if(isNaN(paramValueInt) || paramValueInt < MIN_TTL || paramValueInt > MAX_TTL){
11         ttl = MAX_TTL;
12         "text-purple-400">return ttl;
13      }
14      "text-purple-400">else{
15         ttl = paramValueInt;
16         "text-purple-400">return paramValueInt;
17      }
18}

This function checks for valid TTL values and assigns MAX_TTL as a fallback if provided input is invalid.

This information is especially relevant for:

• Developers implementing product merchandising rules.
• Administrators looking to optimize system performance.
• E-commerce managers aiming to enhance user experience through faster product updates.

Key Takeaways:

• Default caching for product merchandising is set to two hours.
• Modifying the caching duration can reduce time for new rule activation to five minutes.
• Caching performance can be fine-tuned through the adjustment of parameters in DM_SS_Library.js.
• Proper management of caching is essential to balance performance and resource load.
