I have a Magento 2 based website on an AWS EC2 and a AWS RDS . I would like to setup AWS ElastiCache Redis however the only information I found is for Magento 1 and written back in 2014 that says I would end the app/etc/local.xml file
So my question is how would I write the needed code to go into the app/etc/env.php file which is I believe where I would need to edit. I believe I need to edit the section of the file that reads
'session' => array ( 'save' => 'files', ),
However I am not sure what to replace that with.
