## kvrocks with rocksdb_v6 vs rocksdv_v7 report ### Build build current kvrocks and use rocksdb-v7 kvrocks pr is https://github.com/xiaobiaozhao/incubator-kvrocks/pull/4 ### Test steps Test deploy  stress script ``` docker run -d --rm redislabs/memtier_benchmark:latest -t 2 -c 20 -s 172.27.255.230 -p 6666 --distinct-client-seed --key-minimum=100000000 --key-maximum=10000000000 --random-data --data-size=10000 -n 10000000000 --command "set __key__ __data__" ``` kvrocks hardware settings ``` Cores:4C RAM:32GB Disk: nvme SSD 890GB ``` ### monitor > 172.27.255.230 -> kvrocks-v7 > > 172.27.255.229 -> kvrocks-v6 kvrocks-v7 vs kvrocks-v6 full compact monitor ``` 127.0.0.1:6666> COMPACT OK ```  172.27.255.229 disk monitor  172.27.255.230 disk monitor  Other monitoring measures were consistent ### When kvrocks compacting | | kvrocks(v6) | kvrocks(v7) | | ------- | ----------------------------------------------- | ----------------- | | cpu | to lower | normal | | mem | to lower then to higher | normal | | disk | reads doubled and limited 500MB（kvrocks.conf） | a little big high | | ops | to almost zero | normal | | latency | to higher | normal | ### Conclusion 1. I think the v7 version has more consistent performance than v6 in compact 2. I think kvrocks worth upgrading to rocksdb v7 GitHub link: https://github.com/apache/incubator-kvrocks/discussions/1013#discussioncomment-4005680 ---- This is an automatically sent email for [email protected].
