Best Practices for Mercurial Databricks Access Control

Mercurial Databricks access control is the spine of secure collaboration. It dictates who can read, write, execute, or delete. It defines boundaries between projects, repos, and notebooks. Without it, code and data become a free-for-all. With it, teams move fast without breaking trust.

At its core, Mercurial Databricks uses a layered security model. Workspace-level roles determine baseline privileges. Cluster permissions limit computation access to approved users. Notebook and repo ACLs lock down individual assets. Git integration with Mercurial requires mapping these permissions cleanly, so no unauthorized commits slip in.

Set policies before you invite users. Decide on role assignments—Admin, Editor, Viewer. Audit them monthly. Use groups to simplify management and avoid individual permission sprawl. Always combine Databricks’ built-in ACLs with Mercurial repo-level rules. This double lock stops privilege escalation through version control.

Automation matters. Apply access control through APIs whenever possible. Script role creation. Use REST endpoints to sync permissions between Databricks and Mercurial repositories. This reduces human error, which is how most breaches start. Logging every change is the only way to understand who touched what, when, and why.

Never disable audit logs. Store them off-cluster. Connect them to your SIEM pipeline. If you catch anomalies—unexpected repo pushes, rapid role changes—investigate immediately. Set alerts for ACL modifications. Limit who can change policies to a trusted core.

When access control is tight, Mercurial Databricks becomes a fortress with open gates only where you decide. That’s the balance: freedom to build, with absolute control over who’s inside.
