Configure the batch size for the GetMappingsForIdFromDbCommand requests

Version:

The GetMappingsForIdFromDbCommand method fetches catalog mapping entries in batches. The batch size is configurable and is set to 20 by default: <getCatalogMappingsForIdsBatchSize>20</getCatalogMappingsForIdsBatchSize>.

To change the batch size of Sitecore IDs to fetch in a GetMappingsForIdFromDbCommand request:

In the App_Config\Include\Y.Commerce.Engine\CustomCommerce\Custom.Commerce.Engine.Connect.config file (or in your own patch file), in the <commerceEngineConfiguration> node, add a patch with the desired number of Sitecore Id's per batch, for example:

 <configuration xmlns:patch="http://www.sitecore.net/xmlconfig/" xmlns:role="http://www.sitecore.net/xmlconfig/role/">
  <sitecore role:require="Standalone or ContentDelivery or ContentManagement">
...
    <commerceEngineConfiguration type="Sitecore.Commerce.Engine.Connect.CommerceEngineConfiguration, Sitecore.Commerce.Engine.Connect">
    <!-- Specifies the batch size for the GetCatalogMappingsForIds request -->
      <getCatalogMappingsForIdsBatchSize patch:instead="getCatalogMappingsForIdsBatchSize">25</getCatalogMappingsForIdsBatchSize>
    </commerceEngineConfiguration>
