Updating index: Replacing data directory recommended?

[Peter Karich <pe...@yahoo.de>]

Hi solr community!

Is it recommended to replace the data directory of a heavy used solr 
instance?
(I am aware of the http queries, but that will be too slow)

I need a fast way to push development data to production servers.
I tried the following with success even under load of the index:
mv data dataOld; mv dataNew data; and reloaded the index.
Did I have luck or will this always work under linux?
And do I need to cut the production load from the solr instance?

Or is there a better way for a fast index update or index replacement?

Kind regards,
Peter.

Hi

Ups, sorry. I didn't recognized the answer because it was in the bulk 
folder.

I though with this procedure it will be a lot faster and less overhead.
Just two lines of shell script.

What do you think?

Peter.

This should work on Linux. The rsync based replication scripts used to do
something similar.
