Description

Use Case

Would be nice to have Oracle support for this plugin. Plenty of legacy companies - including mine - use Oracle and could benefit from this.

I began building it out in a separate plugin myself, however, I noticed my logic was becoming more or less a copy of the SQL output plugin! I am more than happy to implement the support myself, I just wanted to confirm you are okay with this functionality being added before moving on with it.

Expected behavior

  • Creates valid Oracle connection string
  • Builds TableExists and TableListColumns templates in an Oracle dialect (would just be an if statement similar to the if driver == 'sqlite' in the Init())
  • Creates placeholders that align properly with Oracle syntax
  • all integrated into the SQL output plugin

Actual behavior

No Oracle option exists yet nor have I implemented it myself. Users currently have to build it custom if they want Oracle integration. Open sourcing Oracle integration would allow a shared Oracle option, bringing about all the benefits that come with open source.

Research direction
The issue requests adding Oracle driver support to the SQL output plugin in Telegraf. The main file to modify is likely plugins/outputs/sql/sql.go, where the Init() function contains driver specific logic (e.g., for SQLite). The contributor should examine how other drivers are handled and add similar logic for Oracle, including building the connection string, implementing TableExists and TableListColumns templates in Oracle dialect, and using appropriate placeholders. The existing implementation for other drivers like SQLite serves as a reference. No linked PRs or maintainer comments yet, so the contributor should proceed with implementation and open a PR.
