I have Magento 2.3.1 on digitalocean plesk panel

It shows error like bellow

[2019-04-22 11:36:49] main.WARNING: Memory size allocated for the temporary table is more than 20% of innodb_buffer_pool_size. Please update innodb_buffer_pool_size or decrease batch size value (which decreases memory usages for the temporary table). Current batch size: 100000; Allocated memory size: 130000000 bytes; InnoDB buffer pool size: 134217728 bytes. [] []

Looks like problem with Category Products index. In custom module in etc/di.xml decrease the number for batchRowsCount.

<type name="Magento\CatalogInventory\Model\Indexer\Stock\Action\Full">
        <argument name="batchRowsCount" xsi:type="array">
            <item name="configurable" xsi:type="number">1000</item>

More details here.

  • May i know which path?
