Elasticsearch Index Engine

Elastic Stack Elasticsearch
1

Excerpt from the Elastic search API:
http://www.elasticsearch.org/guide/reference/api/admin-indices-refresh/

It says:

The refresh API allows to explicitly refresh one or more index, making all
operations performed since the last refresh available for search. The
(near) real-time capabilities depend on the index engine used. For example,
the robin one requires refresh to be called, but by default a refresh is
scheduled periodically.

I wanted to ask that do we've any other index engine other than robin where
i can try out the refresh capabilities.

Thanks

ha! this brings back memories, whe ES was created the idea was that it would possibly have multiple engines in a similar manner to other systems. in practice, it ended up having a single implementation, called robin, which us e lucene NRT (near real time search) support, requiring to refresh an index in order to make the latest changes available for search (this is done automatically in ES by default every second)

Hi Kimchy,

Thanks for the reply.

If we will use memory store, then after how much time, the in memory data
is available for search?.

Also, after how much time, the data will be flushed into disk?.

Thanks,
Ankit
