Preloading docs for cache warming

Elastic Stack Elasticsearch
1

Hello experts,

My impression so far is that there are two notable bottlenecks in ES:

  1. Disk I/O - loading documents
  2. CPU pegging while searching/filtering

Is there a good way to pre-load documents? In other words, if I don't want
to figure out the cache warming queries, can I at least pre-empt the disk
I/O problem?

Thanks,
Val

There should be a feature coming out in the next version of elasticsearch
that will warm up new segments without needing a warming query.

Never used it myself (I don't work off master builds), but it might be what
you are requiring.

Cheers,

Ivan
