How to set the reindex batch size when disabling Index All Article Versions Enabled

Issue

• When we use the default value (true) of the System Settings -> Web Content -> Index All Article Versions Enabled option, we use the com.liferay.journal.model.JournalArticle=1000 property to limit the number of articles reindexed at a time
• However, if we set this option to false, the property stops working and we get an exception during the reindex: 

[HTTP/1.1 413 Request Entity Too Large]_]

Environment

• Liferay DXP 7.4

Resolution

• If the above option is set to false, then you need to use the com.liferay.journal.model.JournalArticleResource=1000 property instead
• The value used here is the default one, you should configure it to your preferences
