Product Architecture

UClickhouse is designed as a Clickhouse cluster + Zookeeper cluster, with the following specific features:

  • Zookeeper cluster and Clickhouse cluster are deployed separately on different cloud hosts.

  • Zookeeper is designed as a three-node cluster, and Clickhouse is designed as a single cluster with multiple shards and dual replica structure.

  • Each replica (node) is deployed on a separate cloud host, with each cloud host providing only one shard’s replica service.

Product Features

Key features include:

  • Naturally supports column-oriented data compression with a high data compression ratio.
  • Multi-core parallel processing allows for the natural parallelization of large queries, utilizing all necessary available resources on the current server.
  • Vectorized computing engine processes data not only by columns but also by vectors (part of a column) for high CPU efficiency.
  • Data replication and integrity support use asynchronous multi-master replication, where all remaining replicas will retrieve their copies in the background after writing to any available replica.
  • SQL support with a SQL-based declarative query language, which in many cases aligns with the ANSI SQL standard.
  • Adaptive Join Algorithm.
