ElasticSearch
Config
List any changed config values here!!!
/etc/elasticsearch/elasticsearch.yml:
network.host: localhost discovery.type: single-node xpack.security.enabled: true
/home/mastodon/.env.production
idk if we should put this part online but there is some config here too
Memory
the ES docs say to allocate half your available memory to the heap. At the moment (23-10-26) we are using 2.5G/8G memory at rest. Going to try allocating 3GB and see what happens
/etc/elasticsearch/jvm.options.d/heap.options
-Xms3g -Xmx3g

Since we are running on a small VPS, we might need to configure it for a low memory environment!
