dltlint
Lint Databricks Lakeflow (DLT) Declrative pipeline YAML/JSON configuration files.
Why
The Asset Bundle validate does not check actual configuration values inside pipeline definitions. This library fills that gap and provides clear actionable errors and warning messages.
Installation
pip install dltlint
Usage CLI
# Lint current repo recursively
dltlint
# JSON output for tooling
dltlint --format json
# Fail build on warnings or worse
dltlint --fail-on warning
# Print a success message when clean (otherwise silent on success)
dltlint --ok
Exit codes
- 0 → clean OR no matching files
- 1 → findings at/above threshold (--fail-on)
- 2 → fatal error (e.g., unreadable file)
dltlint discovers:
- *.pipeline.yml,
- *.pipeline.yaml
- *.pipeline.yml.resources,
- *.pipeline.yaml.resources
