clickhouse-plantuml 0.1.1

Generates PlantUML diagrams for clickhouse databases

PlantUML generator for ClickHouse tables

This is a very early version of diagrams generator. It parses system.tables table and produces PlantUML diagrams source. Here's example of produced diagram:

@startuml
!define Table(x) class x << (T,mistyrose) >>
!define View(x) class x << (V,lightblue) >>
!define MaterializedView(x) class x << (m,orange) >>
!define Distributed(x) class x << (D,violet) >>
