By default, the batch size is configured on the following virtual type: - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched` This virtual type sets the constructor argument: - `batchSize` and the module assigns it the default value: - `Klevu\Indexing\Constants::DEFAULT_INDEXING_BATCH_SIZE` ### How to override the batch size To use a custom batch size, add a DI override in your custom module’s `etc/di.xml` and set a numeric value for the `batchSize` argument. Example: ```xml 500 ``` ### Why this works The module declares a shared batched provider: - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched` Other batched product provider variants inherit from it, including: - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched\Simple` - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched\Virtual` - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched\Downloadable` - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched\Bundle` - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched\Grouped` - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched\Configurable` - `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched\ConfigurableVariants` Overriding the shared `Batched` type updates the batch size used by all of these, unless a more specific subtype override is also declared. ### Example use case If you want to increase the number of products processed in each batch during discovery, set a larger value such as: ```xml 500 ``` If you want smaller, more conservative processing batches, use a lower value. ### Notes - The value must be numeric. - This change should be added in a custom module, not by editing the vendor module directly. - After updating DI configuration, run the appropriate Magento cache/compiled dependency refresh steps for your environment. ### Summary To pass a custom `batchSize`, override this DI argument in your custom module: - Type: `Klevu\IndexingProducts\Service\Provider\ProductEntityProvider\Batched` - Argument: `batchSize` Example: ```xml 500 ```
