What is the future plan on shadow index?


(Xudong You) #1

I am interested in the shadow index feature, but find following statement:
"This functionality is experimental and may be changed or removed completely in a future release."
from https://www.elastic.co/guide/en/elasticsearch/reference/master/indices-shadow-replicas.html

So what is the future plan on shadow index? I am afraid it will be removed later on if I use it in our production.

Hi Youxu,

That warning is mostly there because the feature has not been widely used yet, and it's liable to having the API change if we deem it necessary.

That said, we don't have any plans to remove the feature at all right now, so I would feel free to use it.

Thanks for clarification.
