Re: how to start GarbageCollector

why is solr copy my complete index to somewhere when i start an delta-import?

i copy one core, start an full-import from 35Million docs and then start an
delta-import from the last hour (~2000Docs).
dih/solr need start to copy the hole index... why ? i think he is copy the
index, because my hdd-space starts to increase imediatly ...


my live core ended a delta in 5-10 seconds !?!?!?!?!?!?


i run jconsole during this time, what say it to me ?
