Questions about gateways and storage?

Hi there,

Once again, sorry if my question seems childish.

Can someone explain to me what is behind gateways, shared storage and what
is the benefit of using things like hadoop plugin ?

Is there a documentation about this ?

PS : you probably know but most of the documentation links found on google
are broken

thks

The gateway concept allows for long term persistency of the cluster (state + indices). Explained here: Elasticsearch Platform — Find real-time answers at scale | Elastic.

The two main types are the local gateway, allowing ot recover the state of the cluster using the local storage of each node. And a shared gateway (shared file system, hadoop, s3) which can store the data in a remote storage that is accessible to all data nodes.
