only you have to run this comman in you terminal
php bin/magento module:disable {Magento_Elasticsearch,Magento_InventoryElasticsearch,Magento_Elasticsearch6,Magento_Elasticsearch7}
hi, im using 8vcpu and 160GB RAM and elasticsearch is going down every day, load average is 0.4, almost nothing, did you find a solution?
The solution is: downgrade to openmage. More speed, less resources, many free extensions (100% compatible with Magento 1.9), easy to develop modules and templates and ... doofinder as search engine! Lightning speed in product search with product image thumbs.
Yes, you can run using the StarFlare solution that leverages Apache Solr. We have many large customers running this combo. ES doesn't need to run. DM for more info, or search my Avatar.
Note: Tested up to 2.4.4p2 and PHP 7.4.x
Good Luck!
