Git-Aware Schemas

msh automatically creates isolated schemas for each git branch, preventing developers from overwriting each other's data.

How It Works

When you run msh run in dev environment, msh:

1. Detects your current git branch
2. Sanitizes the branch name (replaces /, -, . with _)
3. Appends it to your schemas

Examples

Branch Name	Schema Suffix	Full Schema Name
main	main	main_main
feature/new-api	feature_new_api	main_feature_new_api
bugfix/issue-123	bugfix_issue_123	main_bugfix_issue_123

Production Behavior

Production deployments (--env prod) always use standard schemas without suffixes:

• main (not main_main)
• msh_raw (not msh_raw_feature_new_api)

Fallback Behavior

If git is unavailable (not a git repo, git command fails), msh defaults to local suffix:

• main_local
• msh_raw_local
