Example covering ideal shard size + how to adjust # of primary, replicate shards for an index - ev2900/OpenSearch_Index_Shard_Size
This page shows how to configure process namespace sharing for a pod. When process namespace sharing is enabled, processes in a container are visible to all other containers in the same pod.
You can use this feature to configure cooperating containers, such as a log handler sidecar container, or to troubleshoot container images that don't include debugging utilities like a shell.
Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.
Elasticsearch currently provides 3 different techniques for fetching many results: Pagination, Search-After and Scroll. To learn how to...

Pretty Results
When appending ?pretty=true
to any request made, the JSON returned will be pretty formatted (use it for debugging only!). Another option is to set ?format=yaml
which will cause the result to be returned in the (sometimes) more readable yaml format.
Human readable output
Statistics are returned in a format suitable for humans (e.g. "exists_time": "1h"
or "size": "1kb"
) and for computers (e.g. "exists_time_in_millis": 3600000
or "size_in_bytes": 1024
). The human readable values can be turned off by adding ?human=false to the query string. This makes sense when the stats results are being consumed by a monitoring tool, rather than intended for human consumption. The default for the human flag is false.
A large number of shards on an Elasticsearch cluster requires extra resources. Learn key ways to avoid and correct oversharding in this helpful guide.
