Hi Rekha,

Do you know about Solr's Time Routed Aliases feature[1]?

How to archive Solr cloud and delete the data?

[Rekha]

Hi Solr Team, I want to archive my Solr data. Is there any api available to 
archive data? I planned to read data by month wise and store that into another 
collection. But this plan takes long time, as like adding new data and new 
indexing. And when I delete the archived data from the main collection disk 
size not get changed,  I mean after deletion also data directory size is same. 
Deleted documents count only updated on the admin GUI. When I Google for this, 
some body says based on merged policy when the deleted documents reached 
50%,then only it will removed from the disk. I didnt clear with it. How 
can I delete and retain the deleted document space? Which is the best way to 
archive data? Thanks, Rekha K
