Well, the point is as follows. We have a mysql table where all the changes are tracked something very simular to your situation. The first problem is that, the delta-import on the live core needs to update this table to notify a record is done. I do this very awfull now within a script transformer, offcourse DIH isn't designed for this.
The second thing is, that if the rebuild is running on the rebuild core, we want to do a delta-import on this new core to make it less behind from the live core but also while the rebuilding process is ongoing also the delta-import on the live core runs every minute. The second problem is that the delta-import on the live core already set's these rows to status 'processed' and the delta-update after the rebuild wouldn't pick up these updates anymore. There are some solutions but I can't figure out a clean way to solve this architecture problem. Maybe there isn't a clean solution.. I am curious how other developers experiencing this thing.. -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-core-swap-after-rebuild-in-HA-setup-High-traffic-tp3826461p3826835.html Sent from the Solr - User mailing list archive at Nabble.com.
