…ronments This adds the missing SUPERSET__SQLALCHEMY_EXAMPLES_URI environment variable to the ECS task definition used by showtime ephemeral environments. Without this configuration, showtime environments were unable to load examples because the container didn't know where to find the DuckDB examples file that was downloaded during Docker build (via LOAD_EXAMPLES_DUCKDB=true). The URI matches what's used in docker-compose.yml and docker-compose-light.yml, with read-only access mode for safety in ephemeral environments. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>
This fixes an issue where the LOAD_EXAMPLES_DUCKDB build argument was being ignored during multi-stage Docker builds, causing showtime ephemeral environments to fail loading examples. Problem: The ARG was declared inside the python-common stage, making it unavailable when passed via --build-arg to the showtime target. Solution: Move the ARG declaration to global scope (before any FROM) and re-declare it in the python-common stage where it's used. This follows Docker's multi-stage build ARG scope rules. This fix ensures that when showtime builds with: docker buildx build --build-arg LOAD_EXAMPLES_DUCKDB=true --target showtime The DuckDB examples file will actually be downloaded during the build. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude <[email protected]>

Summary
This PR fixes two critical issues preventing DuckDB examples from loading in showtime ephemeral environments:
LOAD_EXAMPLES_DUCKDBbuild argument was being ignoredunhashable type: '_duckdb.typing.DuckDBPyType'errorsProblems Fixed
1. Docker Build Argument Scope
Issue: The
LOAD_EXAMPLES_DUCKDBARG was declared inside thepython-commonstage, making it unavailable when passed via--build-argto theshowtimetarget in multi-stage builds.Fix: Move ARG declaration to global scope and re-declare in the stage where it's used.
2. DuckDB Version Compatibility
Issue: Current versions
duckdb==1.3.2andduckdb-engine==0.17.0have type system compatibility issues with Superset's DuckDB integration, causing connection failures.Fix: Use proven working versions
duckdb==0.10.2andduckdb-engine==0.12.1(same as motherduck config).Testing
✅ Local testing confirms both fixes work:
Before/After
Before:
LOAD_EXAMPLES_DUCKDB=true→ No examples file downloadedAfter:
Impact
This enables showtime ephemeral environments to successfully load and display examples, making them much more useful for testing and demonstration purposes.
