Questions about gateways and storage?


(Alexandre Heimburger) #1

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: http://www.elasticsearch.org/guide/reference/modules/gateway/.

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.
