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.

A geo-distributed cluster is a cluster whose nodes are located in several geographically distant data centers. This solution ensures high reliability of the system, which will remain operational even if one of the data centers fails.
Sharding is a database design principle that suggests locating parts of the same table on different shards. A shard is a cluster node that can consist of one or more replicas. Replicas are servers that duplicate data within a shard. SELECT and INSERT queries can be sent to any replica of a shard, there is no dedicated master.
