Can someone please suggest how to understand the formula for open_file_memory on this page: http://docs.basho.com/riak/latest/ops/advanced/backends/leveldb/#Parameter-Planning
1. It definitely lacks some brackets, the correct formula is: OPEN_FILE_MEMORY = (max_open_files-10) * (184 + (average_sst_filesize/2048) * (8+((key_size+value_size)/2048 +1)*0.6)) 2. How to estimate average_sst_filesize? 3. does the result estimate the memory used by a single open file in any particular vnode? Or by a single vnode with max_open_files open? As max_open_files is a per vnode parameter then how to estimate the maximum memory used by leveldb if all vnodes have all max_open_files open? is it result*ring_size or result*ring_size*max_open_files? Thanks! -- Oleksiy
