DBSherlock: A performance diagnostic tool for transactional databases

DBSherlock: A performance diagnostic tool for transactional databases Yoon et al. SIGMOD ’16 …tens of thousands of concurrent transactions competing for the same resources (e.g. CPU, disk I/O, memory) can create highly non-linear and counter-intuitive effects on database performance. If you’re a DBA responsible for figuring out what’s going on, this presents quite a challenge. … Continue reading DBSherlock: A performance diagnostic tool for transactional databases
