"compaction_style=kCompactionStyleUniversal" in the bluestore_rocksdb_options .
Here is the option I am using..
bluestore_rocksdb_options = "max_write_buffer_number=16,min_write_buffer_number_to_merge=2,recycle_log_file_num=16,compaction_threads=32,flusher_threads=8,max_background_compactions=32,max_background_flushes=8,max_bytes_for_level_base=5368709120,write_buffer_size=83886080,level0_file_num_compaction_trigger=4,level0_slowdown_writes_trigger=400,level0_stop_writes_trigger=800,stats_dump_period_sec=10,compaction_style=kCompactionStyleUniversal"
Here is another one after 4 hours of 4K RW :-)...Sorry to bombard you with all these , I am adding more log for the next time if I hit it..
