Michael Dürig commented on OAK-7947:
------------------------------------
Would it be feasible to add a way for users to trigger downloading of indexes?
This could be used to e.g. start downloading indexes in the background or for
pre-warming instances before switching them live.
Arguably this is a topic for a separate issue and lets follow up in a one if
this is feasible at all. If not, lets forget it.

> Right now, all Lucene index binaries are loaded on startup (I think when the
> first query is run, to do cost calculation). This is a performance problem if
> the index files are large, and need to be downloaded from the data store.
