I'm not sure if we want to do a small rename here too (and below), and replace the term "dbt_core" with "dbt1", wdyt?

I'd keep dbt_core here: this variable/helper (get_dbt_core_version()) reads the literal version of the installed dbt-core package, which isn't strictly dbt 1.x — the 2.x pre-releases (e.g. 2.0.0b2, which our CI's 2.x target installs) also ship as dbt-core, and the branch right below routes those to the dbt v2 runner. Renaming it to dbt1 would be inaccurate for that case. The dbt-1.x-only concepts (the runner methods) now carry the DBT1_ prefix instead. Happy to rename if you still prefer it though.

Just to make sure - is this check still reliable to verify dbt2 installation?
There was a problem hiding this comment.
Yes for all the supported install paths, with one pre-existing edge case:
pip install dbt/pip install dbt-oss→ detected via package metadata (the newget_dbt2_package_version(); the>= 2guard means a legacy 1.xdbtmetapackage doesn't count).- The official curl installer (
install.sh) → covered by the~/.local/bin/dbtfallback, which is where it places the binary. - Custom locations →
DBT_FUSION_PATH.
The edge case (unchanged from #2333): the ~/.local/bin/dbt fallback trusts that path without verifying it's actually Fusion, so e.g. a pipx-installed dbt-core 1.x (pipx also links entrypoints into ~/.local/bin) would be a false positive — and since dbt v2 now takes precedence, that env would wrongly route to Dbt2Runner (recoverable via DBT_RUNNER_METHOD=api). If you want, I can harden the fallback by sniffing dbt --version output before trusting it — say the word and I'll add it.
Conversely, a Fusion binary at a non-standard PATH location with no pip metadata isn't detected as dbt v2 (falls back to the 1.x subprocess runner) — that's what DBT_FUSION_PATH is for.
dbt-clickhouse 1.10.3 sends lightweight_deletes_sync as a default connection setting, which only exists on ClickHouse >= 24.5 (24.3 rejects it with UNKNOWN_SETTING on the first command). Co-Authored-By: Itamar Hartstein <haritamar@gmail.com>

Review (community — addresses #2354)
Looked at the branch locally and ran py.test -vvv unit/clients/dbt_runner/test_factory.py — 24 passed.
Packaging
- Base wheel METADATA has no unconditional
dbt-core;dbt-core (>=1.8,<2.0.0)only appears behind warehouse /dbt1-*/allextras. That matches the goal in #2354 (co-install withdbt2.x without pip downgrading the project’s dbt). - Explicit
dbt-corein every extra (including legacysnowflake, etc.) is the right guard against adapters resolving a future dbt-core 2.x line.
Runtime
get_dbt_runner_method()ordering (dbt v2 first, then dbt-core 1.x API/subprocess, PATH fallback,NoDbtInstallationError) is clear and well covered by tests.get_dbt2_package_version()checking bothdbtanddbt-osswithmajor >= 2addresses the reporter’s Fusion install path.- Legacy
API/SUBPROCESSenum aliases preserveDBT_RUNNER_METHODcompatibility — good.
CI follow-up (non-blocking)
The Install dbt Fusion step still runs pip uninstall -y dbt-core with a comment that elementary pulls it in. After this PR, pip install "." for fusion targets should not install dbt-core anymore, so the uninstall is redundant and the comment is misleading. Suggest either:
- drop the uninstall and update the comment in this PR, or
- a tiny follow-up right after merge.
(CodeRabbit’s AWS refresh note on Spark looks answered; I didn’t re-open it.)
Docs
#2361 lines up with the two-path install story here; left a short note there as well.
Overall: This looks ready to merge from a #2354 perspective once maintainers are happy with review. Adding Closes #2354 to the description would help link the issue.
Suggested CI cleanup (optional, same PR or follow-up)After optional ```diff
``` Happy to open a tiny follow-up PR after merge if you prefer to keep #2360 focused. |

Summary
Removes the CLI's hard dependency on
dbt-core, now that dbt v2 ships as thedbt/dbt-ossPyPI packages whiledbt-corestays on 1.x (CORE-1477, follow-up to #2333).Installation examples
dbt Core 1.x — install the CLI with the adapter extra for your warehouse; this pulls in
dbt-core1.x + the adapter (exactly as today):dbt v2 (Fusion engine) — no extra and no Python dbt dependency; install the CLI plain and install dbt v2 alongside it whichever way you prefer:
In both cases
edrauto-detects the installation and picks the right runner; if dbt-core 1.x and dbt v2 coexist in one env, dbt v2 wins andDBT_RUNNER_METHOD=apiforces dbt-core 1.x.Changes
dbt-core = ">=1.8,<3.0.0"requirement. dbt-core 1.x comes through the adapter extras, and dbt v2 needs no Python dependency at all.dbt1-<warehouse>aliases (e.g.dbt1-snowflake) for every existing extra, plusdbt1-all. The new names are the ones the docs will use; the old names remain supported indefinitely. All extras (new and legacy) now also explicitly includedbt-core >=1.8,<2.0.0, so they can never resolve a dbt-core 2.x release (the adapters themselves only lower-bound dbt-core).dbt_installation.py):get_dbt_package_version()→get_dbt2_package_version(), which checks both thedbtanddbt-ossdistributions and only counts versions>= 2(a legacy 1.xdbtmetapackage doesn't qualify).get_dbt_runner_method()):RunnerMethod.API/SUBPROCESSrenamed toDBT1_API/DBT1_SUBPROCESSto make it clear they drive dbt-core 1.x; the old names remain as enum aliases (same values), so existing callers andDBT_RUNNER_METHOD=api|subprocesskeep working.DBT_RUNNER_METHOD=api).dbtexecutable is on PATH (e.g. system-wide/pipx dbt 1.x without pip metadata in the venv), fall back toDBT1_SUBPROCESSas before.NoDbtInstallationErrorwith actionable install instructions instead of failing later with an obscure subprocess error.No behavior change for the documented install paths:
elementary-data[<warehouse>]users get the exact same resolution as today (unless they also install dbt v2, which now wins).CI fixes (unrelated breakage that surfaced on this PR):
