 # Benchmark Experiment Host Manager (Bexhoma)
 This Python tools helps **managing benchmark experiments of Database Management Systems (DBMS) in a Kubernetes-based High-Performance-Computing (HPC) cluster environment**.
 It enables users to configure hardware / software setups for easily repeating tests over varying configurations.
 
 It serves as the **orchestrator** [2] for distributed parallel benchmarking experiments in a Kubernetes Cloud.
 This has been tested at Amazon Web Services, Google Cloud, Microsoft Azure, IBM Cloud, Oracle Cloud, and at Minikube installations,
-running with Clickhouse, Exasol, Citus Data (Hyperscale), IBM DB2, MariaDB, MariaDB Columnstore, MemSQL (SingleStore), MonetDB, MySQL, OmniSci (HEAVY.AI), Oracle DB, PostgreSQL, SQL Server, SAP HANA, TimescaleDB, and Vertica.
