Hi, I'm looking for a formula to calculate filterCache size in the RAM. The best estimation I can find is here http://stackoverflow.com/questions/2004/solr-filter-cache-fastlrucache-takes-too-much-memory-and-results-in-out-of-mem An index of 1.000.000 would thus take 12,5 GB in the RAM with t

Solr Filter Cache Size

How can we calculate how much heap memory the filter cache will consume? We understand that in order to determine a good size we also need to evaluate how many filterqueries would be used over a certain time period. Here's our setting: According to the post below, 53 GB of RAM would b
