I'm using Solr Java replication with multiple master cores ("at_bat" & "on_deck"), and a single slave core ("at_bat")
The "at_bat" cores of the master and slave are used for processing search requests, and the "on_deck" core is used for complete index rebuilds. Once a rebuild is complete, the "at_bat" core is SWAPped with the "on_deck" core. The single slave core is configured to poll the master "at_bat" core. When the swap occurs, the slave detects the version change, and then the entire set of index files is replicated to a new index.YYYYMMDDhhmmss directory. Does anyone have advice on this approach; findings, issues encountered, possibly a way to work around the ever-growing copies of core data directories without having to use custom cleanup scripts? -Kelly
