System configuration

Elasticsearch configuration may lead to a number of performance and reliability issues, as mentioned in Chapter 2, Installation and the Requirements for Elasticsearch. A quick reminder that the most important configuration changes to make to your cluster are as follows:

Ensuring that the Elasticsearch heap size (ES_HEAP) is set to 1/2 of available system memory, but does not exceed 31 GB. Set this value in /etc/defaults/elasticsearch
Disabling memory swapping
Locking the Elasticsearch address space into memory by setting bootstrap.mlockall: true in elasticsearch.yml

Refer to Chapter 2, Installation and the Requirements for Elasticsearch, for more detailed instructions on how to set these values.

Ever wonder why speech recognition systems don't understand the Scottish accent, or what would happen if an astronaut only ate mac 'n' cheese, or other spurious reflections you'd have at a bar? We did, then collated those deliberations into absurd research articles with fake figures and methodologies inspired by even more fictionally absurd studies.
