Branching Workflows

Turns copy-on-write branching into everyday practice. Following the lecture-demo pattern, learners create branches four ways, recover data with point-in-time branches, manage the branch lifecycle (protect, reset, delete), and choose a branching strategy with per-workload TTLs — including branch-per-PR CI/CD. Branches are the feature that lets developers pair a code branch with a database branch. Two real OrderOps admin apps, one bound to each branch, make isolation tangible: learners edit orders in each app and prove changes never cross branches, then graduate a schema change from the dev branch to production by re-running the migration and shipping the new app version.

Note: Databricks Academy is transitioning to a notebook-based format for classroom sessions within the Databricks environment, discontinuing the use of slide decks for lectures. You can access the lecture notebooks in the Vocareum lab environment.

Prerequisites

The content was developed for participants with these skills/knowledge/abilities:

• Comfort with the Python SDK and basic SQL

• Ability to create and connect to a Lakebase project (from LB-103)

• Understanding of copy-on-write branching at a conceptual level (from LB-102)

Suggested prior courses: LB-103 First Steps (create, connect, query) and LB-102 Architecture Deep Dive (the copy-on-write concept this course operationalizes). LB-101 for overall context.

Connecting and Authentication Patterns

Makes Lakebase connections production-grade. Following the lecture-demo pattern, learners compare OAuth tokens and native passwords, handle the 60-minute token lifetime with refresh, and build a token-refreshing connection pool in both SQLAlchemy and raw psycopg — sized against the endpoint's connection ceiling and observed through pg_stat_activity. The course concludes with the Lakebase Data API, showing how the authenticator role brokers identity via SET ROLE to enforce the same privilege model over HTTP.

Autoscaling and Scale-to-Zero

Turns the compute/storage split into a cost lever. Following the lecture-demo pattern, learners diagnose a fixed-compute bill, configure the autoscaling CU range, enable scale-to-zero with the right timeout, weigh the HA cold-start trade-off, and apply per-branch configs across production, dev, and agent-test to compute the resulting monthly bill.
