feat: add observability_pipelines resource type

[michael-richey]

Summary

Adds support for syncing Datadog Observability Pipelines as a new resource type (observability_pipelines), using the v2 API at /api/v2/obs-pipelines/pipelines.

Changes

• New model datadog_sync/model/observability_pipelines.py — ObservabilityPipelines(BaseResource) with:

  • LIST — paginated GET /api/v2/obs-pipelines/pipelines (uses client.paginated_request, matching the default PaginationConfig of page[size]/page[number] with response_list_accessor="data").
  • Import — GET .../pipelines/{id} for the per-ID path; pass-through for the list path. Unwraps the {"data": ...} envelope.
  • Create — POST .../pipelines with {"data": resource}. If the source id already exists in the destination map, delegates to update_resource (id-keyed dedup, mirroring logs_metrics).
  • Update — PUT .../pipelines/{destination_id} with {"data": resource}. Re-injects the destination id into the resource before the PUT (PUT, not PATCH — matches the OP API and the precedent of logs_indexes/dashboards).
  • Delete — DELETE .../pipelines/{destination_id}.
  • Config — resource_mapping_key="id", excluded_attributes=["id"] (strips the server-assigned id from create payloads and from diff comparisons via prep_resource).
  • No cross-resource resource_connections — an OP pipeline config (sources/destinations/processors) references external systems via embedded connection settings, not sync-cli-managed Datadog resource IDs.

• Registration — datadog_sync/models/__init__.py imports ObservabilityPipelines so init_resources discovers it via models.__dict__.

• --id-file support — added observability_pipelines to _ID_FILE_IMPORT_SUPPORTED_TYPES. The default import_resource(_id=...) does a real GET, and the default get_resources_by_ids classifies 404/429/5xx/403 without aborting (satisfies the continue-past-errors design).

• README — added observability_pipelines to the supported-resources table.

• Integration test stub — tests/integration/resources/test_observability_pipelines.py, skipped (OP pipelines hold downstream routing config; destructive cleanup against a real org is unsafe for CI).

Design decisions

• Match by id (not attributes.name) — mirrors logs_metrics. Source and destination UUIDs differ, so the first sync of a pipeline always creates it on the destination; re-sync idempotency relies on persisted state. This means a pipeline deleted on the destination between syncs would be re-created rather than updated in place.
• PUT for updates — the OP API uses PUT .../pipelines/{pipeline_id}, not PATCH. update_resource re-injects the destination id (stripped by prep_resource) before the PUT.
• No --id-file state-load allowlist entry — the state key is the pipeline id (ID-derivable), but the state-load path scopes by --resources intersection, not by _ID_FILE_STATE_LOAD_SUPPORTED_TYPES. This matches the logs_metrics precedent (also absent from the state-load set).

Testing

• tests/unit/test_observability_pipelines.py — config contract, registration via init_resources, paginated get_resources, import (pass-through + GET-by-id), create (POST + id-keyed dedup), update (PUT with destination id), delete, prep_resource id-stripping, no-op hooks.
• tests/unit/test_observability_pipelines_id_file.py — allowlist membership (import set + union) and import_resource(_id=...) GET-path verification.
• All unit tests pass (1483 passed, 8 skipped). Lint (ruff, black at line-length 120) clean.

Test plan

• Unit tests pass
• ruff and black clean
• Integration test against a live org (deferred — requires cassette; stub is skipped)

[michael-richey]

Thanks for pushing this — the model/test coverage is solid overall, but I found one blocking issue before we merge.

Blocking: pagination config likely mismatches OP list response shape

ObservabilityPipelines.get_resources() uses client.paginated_request(client.get) with the default PaginationConfig.

The default remaining_func in custom_client.py expects resp["meta"]["page"]["total_count"]. For Observability Pipelines, the v2 API/SDK schema exposes list metadata as meta.totalCount (not meta.page.total_count).

That means this code can work for orgs with <100 pipelines (single page), but once a page is full it may hit remaining_func and raise on the missing meta.page key, aborting import/sync for this type.

Can we switch this model to an explicit PaginationConfig for the OP response shape and add a unit test that exercises the multi-page path (not just the paginated wrapper call contract)?

[michael-richey]

Good catch — you're right that the default remaining_func reads resp["meta"]["page"]["total_count"], which would raise KeyError on the OP API's meta.totalCount (camelCase) shape once a full page is returned.

Fixed in 171dc9c:

• Added a custom PaginationConfig with a remaining_func (_op_remaining_func) that reads resp["meta"]["totalCount"] with a safe .get() fallback to 0 (so pagination stops gracefully if meta is absent, rather than raising).
• get_resources now passes pagination_config=self.pagination_config explicitly to paginated_request, instead of relying on the client default.
• Added unit tests:
  • test_pagination_config_reads_meta_total_count — verifies the custom remaining_func arithmetic (totalCount=150, page_size=100 → remaining=50 after page 0, remaining=-50 after page 1).
  • test_get_resources_passes_custom_pagination_config — verifies get_resources passes the model's pagination_config to the inner wrapper, not the client default.

All 1485 unit tests pass; ruff + black clean.

Note on the test-integrations failure: it is a pre-existing infrastructure timeout, not a code issue. The job exceeds the workflow's 60-minute timeout-minutes ceiling at the "Run integration tests" step (cancelled at 1h5m0s). The same scheduled run on main today (2026-09-29, run 36532942739) timed out identically, confirming this is environment-wide and unrelated to this PR. The observability_pipelines integration test is @pytest.mark.skip (destructive cleanup against a real org is unsafe, same rationale as test_spans_metrics.py), so this PR cannot affect the integration suite outcome. test-integrations is not a required status check — only devflow/mergegate is required, and it passes. All unit-test jobs (ubuntu, ubuntu-arm, macos, windows) and all build jobs pass.

Retriggering again would occupy the queue-mode integration-tests concurrency group (cancel-in-progress: false) for another hour and block other PRs, so I'm leaving it. Ready for human review.

[michael-richey]

Update on test-integrations: the latest run (2026-09-30, job 109896678685) actually completed in 33m (not a timeout this time) but failed with 24 integration test failures. The root cause is assert len(source_resources) > 0 in tests/integration/helpers.py:134 — the source test org has no resources to import. The failures span authn_mappings, downtime_schedules, logs_restriction_queries, notebooks, restriction_policies, team_memberships, and test_cli (test_migrate). None are related to observability_pipelines (whose integration test is @pytest.mark.skip). This is a pre-existing test-environment issue — the last successful integration run on main was 2026-08-03, nearly 2 months ago; all runs since have timed out or failed with the same empty-source-org pattern. test-integrations is not a required status check (only devflow/mergegate is required, and it passes). All unit-test and build jobs pass. Ready for human review.

Integration Test Findings — observability_pipelines

Ran the generic integration test framework against PR #725. Fixtures created successfully, but import fails due to a pagination bug.

✅ Fixtures created (3 pipelines)

✅ observability_pipelines-lifecycle-test (id=5ea8632c-...)
✅ observability_pipelines-fuzz-special-chars-üñîcode (id=5f11d1ea-...)
✅ observability_pipelines-fuzz-duplicate (id=5f7ed894-...)

❌ Import fails — pagination page_size too large

ERROR - Paginated request TRUNCATED for /api/v2/obs-pipelines/pipelines
  at page[number]=0 page[size]=100 after collecting 0 resource(s).
Error: 400 Bad Request - {"errors":[{"title":"page[size] must be a number between 1 and 50"}]}

Root cause: The pagination_config in the model uses page_size=100:

pagination_config = PaginationConfig(
    page_size=100,
    ...
)

But the Observability Pipelines API only accepts page[size] between 1 and 50. The GET request fails with 400, so no resources are imported.

Suggested fix: Change page_size from 100 to 50:

pagination_config = PaginationConfig(
    page_size=50,
    ...
)

Test results

Scenario	Result	Notes
Fixture creation	✅ PASS	3 pipelines created in source org
Import	❌ FAIL	Pagination 400 — page_size=100 but API max is 50
Lifecycle (create/update/skip/delete)	⚠️ SKIP	No resources imported
Fuzz import + sync	⚠️ SKIP	No resources imported

What works

• The model file is correctly registered in models/__init__.py
• The base path (/api/v2/obs-pipelines/pipelines) is correct
• The API type field (pipelines) is correct
• The create endpoint accepts the payload with config (sources, destinations, processor_groups)
• The model has destination reconciliation in create_resource (checks _existing_resources_map)

What needs fixing

1. page_size=100 → page_size=50 in pagination_config — the OP API rejects page sizes > 50

[michael-richey]

The create | ❌ fail and fuzz | ❌ fail results in this comment were from a test run against the pre-fix code (page_size=100). The fix was pushed in commit 5d87f32 (fix(observability_pipelines): reduce pagination page_size from 100 to 50) at 2026-10-02T18:24:41Z, ~30 min before this comment was posted — the integration test framework was still running against the old code.

The current branch has page_size=50 and all CI checks pass, including test-integrations (20m57s, 184 passed, 0 failed). The pagination 400 error is resolved.

No error logs or test output for observability_pipelines were found anywhere on disk.

Could you paste the actual error output from the failed test? I need the stderr/stdout from the create and fuzz phases to diagnose the root cause and suggest a fix.

Analysis

Root cause: The observability_pipelines sync-cli model is sending both processors and processor_groups fields in the API request body, but the Datadog API rejects this — it requires only processor_groups. This is a classic excluded_attributes issue: the model likely imports processors from the source org but doesn't exclude it, while also constructing processor_groups, resulting in both being sent to the destination.

Suggested fix: Add processors to the model's excluded_attributes so it's stripped during prep_resource, ensuring only processor_groups is sent to the destination API:

# In the observability_pipelines model file (e.g., models/observability_pipelines.py)
class ObservabilityPipelines(DatadogResource):
    resource_type = "observability_pipelines"
    resource_id_attr = "id"
    excluded_attributes = [
        # ... existing exclusions ...
        "processors",  # API rejects if both 'processors' and 'processor_groups' are present
    ]

Additionally, verify that prep_resource (or create_resource/update_resource) properly transforms processors into processor_groups format, since the source org may store them under processors while the destination API expects processor_groups.

Root Cause

The observability_pipelines resource model is sending both processors and processor_groups fields in the create/update payload, but the Datadog API rejects requests containing both — only processor_groups is allowed.

Suggested Fix

In the sync-cli model file for observability_pipelines (likely models/observability_pipelines.py), add processors to excluded_attributes (or strip it in prep_resource) so the field is removed before the API call:

# In the model class definition
excluded_attributes = ["processors"]

Or if the field needs to be transformed rather than dropped, handle it in prep_resource:

@classmethod
def prep_resource(cls, resource):
    resource = super().prep_resource(resource)
    # API only accepts processor_groups, not processors
    resource.get("attributes", {}).pop("processors", None)
    return resource

This ensures the destination payload only includes processor_groups, matching the API constraint.

# In the observability_pipelines model file

Or, if processors is needed for read/import but must not be sent on write:

def prep_resource(self, resource):
    resource = super().prep_resource(resource)
    if "attributes" in resource and "processors" in resource["attributes"]:
        del resource["attributes"]["processors"]
    return resource

Re-test: attributes.processors exclusion doesn't work — wrong path

The fix (951658e1) added attributes.processors to excluded_attributes, but the error persists:

400 Bad Request - {"errors":[{"title":"Invalid config: cannot specify both 'processors' and 'processor_groups' fields; use 'processor_groups' only"}]}

Root cause

The processors field is nested inside config, not directly in attributes. The API response structure is:

{
  "data": {
    "attributes": {
      "name": "...",
      "config": {
        "processors": [...],      ← HERE, inside config
        "processor_groups": [...],
        "sources": [...],
        "destinations": [...]
      }
    }
  }
}

The excluded_attributes entry attributes.processors doesn't match because the actual path is attributes.config.processors.

Suggested fix

Change the exclusion path to include config:

excluded_attributes=["id", "attributes.config.processors"],

This will make prep_resource strip processors from inside the config object before sending the payload to the destination API.
