I tried to run HTAP test in a distributed DB, but I found it hard due to the lack of good hybrid workload. It would be helpful for me to know more about How TiDB Does.
There’re only a few benchmarks for HTAP. CH-benCHmark may be the most popular one, which consists of an entire TPC-C, additional tables and 22 TPC-H equivalent queries.
I found HTAP experientations in TiDB paper (TiDB: A Raft-based HTAP Database, VLDB industry track, 2020, https://www.vldb.org/pvldb/vol13/p3072-huang.pdf). In Chapter6.1, page 9, it goes "Our experiments are conducted under a hybrid OLTP
and OLAP workload using CH-benCHmark. Source code is published online . "
I found source code in CH-benCHmark author’s website https://db.in.tum.de/research/projects/CHbenCHmark/?lang=en, and it made great performance loss when testing (maybe it’s an awful implementation).
So I really want to get further information about TiDB hybrid workload implementation.
