Description

I would like to contribute an improevemnt for the clickhouse module but I am unsure how to package it.

Clickhouse supports 3 ways of connecting:

  • JDBC (basically only a wrapper around HTTP)
  • Native protocol (CLI only)
  • HTTP
  • MySQL protocol
  • PostgreSQL protocol

The current module supports:

  • JDBC (basically only a wrapper around HTTP)

I'd like to provide a PR supporting MySQL (already got it working) and maybe even PostgreSQL but I am unsure how to package this. The JdbcDatabaseContainer is tied to a specific driver (the one from yandex). Would you rather have individual containers for each one? have a highly configurable container covering all areas? Any example fdrom an existing module that comes to mind?

Cheers, Jochen

Research direction
Examine the existing testcontainers java modules, particularly the Clickhouse JDBC module which uses JdbcDatabaseContainer. Look at how other database protocols are implemented (e.g., PostgreSQL). The issue author has working code but needs to decide between separate containers or a configurable one. Review the project's contribution guidelines and discuss with maintainers in the issue comments to reach a consensus on the best packaging approach.
