Arenadata QuickMarts
Arenadata QuickMarts (ADQM) is a cluster column-oriented DBMS built on ClickHouse. ADQM generates various online analytical reports based on vast amounts of information stored in flat marts. ADQM is much faster than traditional DBMS.
For effective administration of ADQM databases, it is recommended to use ADQM Control — a related product that provides extensive functionality for monitoring and analyzing the state of DBMS at the level of tables, columns, user queries, and cluster hosts.
