Here's everything I wish I'd known before shipping packed into 5 slides. What's inside: <STRONG>What is Lakebase?</STRONG> Fully managed Postgres on Databricks. OLTP for the Lakehouse. No ETL pipelines, no servers. Core capabilities: autoscaling, branching, HA, read replicas, instant restore and Unity Catalog sync all built in. <STRONG>Two versions now exist (since March 2026)</STRONG> Lakebase Autoscaling is the new default. Scales to zero, supports branching and 30-day rollback. Lakebase Provisioned is still supported for existing workloads but gets no new features. Know which one you're on. <STRONG>The 7 roles Lakebase creates automatically</STRONG> Most are internal. The one you actually use is your email role. databricks_superuser sounds powerful but has NOLOGIN it cannot open a database connection. Never put it in your connection string. <STRONG>Lakebase Superuser ≠ Postgres Superuser</STRONG> Same label, completely different behavior. The managed permission model breaks vanilla Postgres assumptions silently. Four real-world gotchas covered with how to avoid each one. <STRONG>Lakebase syncs to Unity Catalog, but not the way you think</STRONG> Four things from the official docs most people discover too late: 15-second minimum sync delay, REPLICA IDENTITY FULL required on every table, no partitioned table support, and only the databricks_postgres database syncs (beta restriction). If you're building on Lakebase or planning to, save this before you ship. #Databricks #Lakebase #DataEngineering&nbsp;#Architecture</PRE><P>&nbsp;</P> Wed, 22 Apr 2026 15:42:32 GMT Dataninsight 2026-04-22T15:42:32Z https://community.databricks.com/t5/mvp-articles/lakebase-your-only-guide-what-databricks-users-need-to-know/m-p/155215#M168 <PRE>Most people spin up Lakebase and hit surprises they didn't see coming.
