How to add the MAGE_INDEXER_THREADS_COUNT environment variable to env.php?

Question

In Magento 2.2.6 you can take advantage of Multi-threading for the indexers as stated in release notes here:

https://devdocs.magento.com/guides/v2.2/release-notes/ReleaseNotes2.2.6EE.html

This states that I need to add a MAGE_INDEXER_THREADS_COUNT variable to env.php. I'm just not sure where to add the variable properly and would like an example of this variable within the env.php file?

Answer 1

You can try adding like 'MAGE_INDEXER_THREADS_COUNT'=>3 then the env.php will look something like following

return [
 'backend' => [
 'frontName' => 'magento226administrator'
 ],
 'crypt' => [
 'key' => '45625508600206a4c2d2f2bf406b23fb'
 ],
 'db' => [
 'table_prefix' => '',
 'connection' => [
 'default' => [
 'host' => 'localhost',
 'dbname' => 'localmagento226',
 'username' => 'magento226',
 'password' => 'magento226db',
 'active' => '1'
 ]
 ]
 ],
 'resource' => [
 'default_setup' => [
 'connection' => 'default'
 ]
 ],
 'x-frame-options' => 'SAMEORIGIN',
 'MAGE_MODE' => 'developer',
 'session' => [
 'save' => 'files'
 ],
 'cache_types' => [
 'config' => 1,
 'layout' => 1,
 'block_html' => 1,
 'collections' => 1,
 'reflection' => 1,
 'db_ddl' => 1,
 'eav' => 1,
 'customer_notification' => 1,
 'config_integration' => 1,
 'config_integration_api' => 1,
 'full_page' => 1,
 'config_webservice' => 1,
 'translate' => 1
 ],
 'install' => [
 'date' => 'Wed, 19 Sep 2018 05:55:55 +0000'
 ],
 'MAGE_INDEXER_THREADS_COUNT'=>3
];

Answer 2

Works if you insert below 'MAGE_MODE' with:

'x-frame-options' => 'SAMEORGIN',
'MAGE_MODE' => 'production',
'MAGE_INDEXER_THREADS_COUNT' => '3',
'session' => [
 'save' => 'memcache',
 'save_path' => 'tcp://memcache:11211'
],
