Subject Solr Cache
Date Sun, 02 Sep 2012 05:52:15 GMT
if we pre assigning the cache values in the solrconfig.xml as follows for
each core [solr 1.3] .IS the RAM memory pre assigned as follows per core
and how much would be used for each  .Would I be able to calculate the RAM
reserved for each cache.since we have many such cores with the same Cache
values ,would  like to forecast the usage.
we have assinged total 19gb RAm for 220 cores with the same config and the
following is the exampe of one core usage.
