Support dbt 2.0 / Fusion in the edr CLI - #2333
Conversation
- Auto-detect the installed dbt flavor (dbt-core 1.x / dbt-core 2.x / binary-only Fusion) via package metadata instead of importing dbt.version - Rename DbtFusionRunner to Dbt2Runner (dbt 2.0 is the Fusion engine); keep 'fusion' as a backward-compatible runner-method alias - Widen dbt-core constraint to <3.0.0 - Migrate the e2e dbt project to dbt 2.0-compatible syntax (dbt-autofix) - Add fusion + dbt-core 2.x CI targets on Fusion-supported warehouses Co-Authored-By: Itamar Hartstein <haritamar@gmail.com>

Set EDR_INTERNAL_TARGET_PATH for every internal dbt run. When it is unset, CommandLineDbtRunner leaves DBT_TARGET_PATH unset, so dbt uses the internal project's relative target directory. This can fail in read-only package installations and share artifacts between concurrent runs.

This preserves the pre-PR behavior exactly: the removed target-path: "{{ env_var('EDR_INTERNAL_TARGET_PATH', 'target') }}" also defaulted to the same relative target directory when the env var was unset, so runs without EDR_INTERNAL_TARGET_PATH behave as they always have. Generating a run-specific default target dir would change artifact locations for all existing callers and is out of scope for this PR — happy to consider it separately if concurrent-run isolation becomes a requirement.

dbt Core 1.10.5 require_generic_test_arguments_property arguments generic tests compatibility dbt 1.8
💡 Result:
In dbt Core 1.10.5, the behavior flag require_generic_test_arguments_property was introduced to resolve ambiguity between generic test input arguments and framework configurations [1]. This flag governs how dbt parses arguments for generic data tests [1]. Historically, dbt accepted test arguments as top-level properties within a test configuration [1]. With this flag, users are encouraged to move these arguments under a dedicated arguments property [1]. Regarding compatibility and usage: - Flag Behavior: When set to false (the default in earlier versions), dbt continues to support the legacy top-level argument syntax but raises an ArgumentsPropertyInGenericTestDeprecation warning [1][2]. When set to true, dbt requires arguments to be nested under the arguments property; failure to do so will trigger a MissingArgumentsPropertyInGenericTestDeprecation warning [1][2]. - Migration: To migrate, update your dbt_project.yml to include the flag in the flags configuration block [1]: flags: require_generic_test_arguments_property: true - Then, update your model YAML files to nest test arguments under the arguments key [1][2]: models: - name: my_model data_tests: - my_custom_generic_test: arguments: my_arg: value - dbt 1.8 Compatibility: This flag and the associated syntax change were introduced in dbt Core 1.10.5 [1][3]. Projects running on dbt 1.8 do not have this requirement, as the flag and the strict parsing behavior were not present in that version [1]. Users upgrading from 1.8 to 1.10.x will encounter these new deprecation warnings as they move toward the stricter standard enforced by the flag [1][2]. The flag matured to a default value of true in dbt Core 1.10.8 [1][3].

Gate E2E runs below dbt Core 1.10.5. The E2E project enables require_generic_test_arguments_property and uses arguments: throughout tests/e2e_dbt_project/models/schema.yml. dbt Core 1.8 and 1.9 do not interpret this syntax as intended, so the tests can run without their configured inputs. The workflow accepts those versions, and pyproject.toml declares dbt Core >=1.8. Add a dbt Core >=1.10.5 gate for E2E runs, or retain the legacy syntax for older targets. Document the separate E2E minimum if the package remains compatible with dbt Core 1.8.

The E2E minimum is now documented in tests/e2e_dbt_project/dbt_project.yml (121dcbf): the arguments: syntax + require_generic_test_arguments_property flag require dbt-core >= 1.10.5 (or dbt 2.x) to run the E2E project. The default CI matrix installs unpinned dbt-core (currently 1.10.x), so it already satisfies this; only a manual dispatch pinning an older dbt-version would hit it, and it fails loudly at parse time. pyproject.toml keeps the package minimum at dbt-core >= 1.8, unchanged.

Summary
Adds support for dbt 2.0 / Fusion to the
edrCLI (CORE-1344). dbt 2.0 is the Fusion engine, installable via pip in two flavors:dbt-core>=2.0(Python wheel, no callback API) anddbt(binary-only platform wheel, no importable Python module at all). Both are driven via subprocess by a newDbt2Runner.Runner auto-detection —
factory.pyno longer importsdbt.versionat import time (which crashes with binary-only Fusion). Instead, the flavor is detected lazily from package metadata (newdbt_installation.py):RunnerMethod.DBT2("dbt2") is added;RunnerMethod.FUSION("fusion") is kept as a backward-compatible alias (dbt-data-reliability CI passes--runner-method fusion), anddbt_fusion_runner.pyre-exportsDbt2RunnerasDbtFusionRunner.Dbt2RunnerreplacesDbtFusionRunner: resolves the binary viaDBT_FUSION_PATHenv var →dbton PATH (only when it can't be a dbt-core 1.x entrypoint) →~/.local/bin/dbt, and no longer skipsdbt deps(Fusion supports it).Fusion compatibility fixes:
target-pathindbt_project.yml, so it was removed from the internal project;EDR_INTERNAL_TARGET_PATHis now translated byCommandLineDbtRunnerinto the standardDBT_TARGET_PATHenv var when running the internal project.dbt-autofix(meta/tags/test args moved underconfig/argumentsinschema.yml), plus a generic test definition for the previously-implicituniquestest.+root_path(a dbt-dremio 1.x config that Fusion rejects) is kept for the Dremio target and stripped by CI for dbt 2.x targets.pyproject.toml:dbt-corewidened to>=1.8,<3.0.0(2.x requires Python ≥3.11; adapter extras stay 1.x-only since 2.0 has adapters built in).CI —
test-warehouse.ymlaccepts dbt-version values:fusion: installs the binary wheel, pinned todbt==2.0.0rc212(stablepip install dbtcurrently resolves to the unrelated dbt Cloud CLI);2.x: installs the latest dbt-core 2.x at run time viapip install --pre "dbt-core>=2.0.0a0,<3", so future betas/RCs/the official release are picked up automatically (an explicit version like2.0.0b3still works for manual-dispatch pinning);test-all-warehouses.ymlgets a separate informationaltest-dbt2matrix on Fusion-supported warehouses (snowflake, bigquery, databricks). dbt 2.x snowflake jobs run withthreads: 1(profile + explicit--threads 1) to work around the Fusion Snowflake driver's concurrent-connection hang (dbt-labs/dbt-fusion#410); the2.x+ snowflake cell is excluded because the current dbt-core2.0.0b2engine hangs on Snowflake even single-threaded — the fusion target covers Snowflake until a newer dbt-core 2.x is released.Verified locally against DuckDB with Fusion 2.0.0-preview.212:
parse,deps,seed,run-operationmarker capture,lsparsing, and the internal target-path translation all work throughDbt2Runner. Unit tests (466) pass; new factory/detection tests added intest_factory.py. The full CI matrix (all dbt 1.x warehouses + fusion on snowflake/bigquery/databricks + dbt-core 2.x on bigquery/databricks) is green.Linear: CORE-1344
