PARTITIONING_COMMENT = <<~SUGGEST_COMMENT
When adding new CI tables, consider [partitioning](https://docs.gitlab.com/ee/development/cicd/cicd_tables.html) the table
from the start if it references any of the larger CI tables: `ci_pipelines`, `ci_stages`, `ci_builds`, `p_ci_builds_metadata`, `ci_job_artifacts`, `ci_pipeline_variables`.
