Our 30G index takes about 980M of memory to open.
Otis and some others suggested changing TermInfosWriter.INDEX_INTERVAL (or specifically a variable that is 128 by default). I grepped through the sources and this is the only one mentioned.
I did a recompile and didn't notice any change in memory footprint. Do I have to re-optimize my index?
What are the pros/cons for this setting? Will I see a performance slowdown on searches becaause of this? I was thinking of changing it to 256/512 to try to get my memory down by 1/2 or 1/4...
Thanks!
Kevin
