elek commented on issue #665: HDDS-3160. Disable index and filter block cache for RocksDB. URL: https://github.com/apache/hadoop-ozone/pull/665#issuecomment-600696161 Thanks @xiaoyuyao the review. > If would be great if you could attach some RocksDB block cache metrics on block cache hit/miss ratio before and after this change, on index/filter/data, respectively. I would be happy to repeat the isolated OM test with and without this patch, but I am not sure If I get good metrics from RocksDB. With moving index/filter out from the cache I think the cache hit / miss will be zero for index / filter all the time. Do you have any more details what are interested about?
