24 Hours:
MetaDataTags -> 24 hours
ProductMetaDataTags Product Classifications (ProductMetaDataTags) -> 24 hours
30 Minutes:
ProductAttribute -> 30 min per product
TerminalConfiguration -> 30 minutes
By Setting:
Inventory pools (Get Inventory For Month call) -> "ecommercesettings.productinventory.cachetime"
NOTE: In the 2.12 release, coming in late October, inventory will be enhanced so it is no longer retrieved from RTP|ONE less frequently, which will improve performance for inventoried products.
Dynamic pricing tables: yieldPriceListTable, yieldProductVariantTable, yieldDaysToArrivalTable -> "ecommercesettings.dynamicpricing.cachetime"
Product Inventory (golf specific): -> "GolfSettings.ProductInventory.CacheTime"
Logical:
If catalog setting "CacheProductPrices" is set to true product prices are cached for 60 seconds
