Code Review
This pull request adds a placeholder file named temp.md. The reviewer noted that this file should be removed as it does not contain the documentation for tidb_opt_index_join_build_v2 mentioned in the pull request description, and suggested placing the documentation in the correct system variable files instead.

This file appears to be a placeholder and does not contain the documentation for tidb_opt_index_join_build_v2 as described in the pull request title and description. Remove this file and include the documentation in the appropriate files (system-variables.md and system-variable-reference.md).
References
- The documentation should be complete and accurate, covering all aspects described in the pull request summary. (link)
