From 7d9ff878547b1f5f267d1b29fd19963b85f7387d Mon Sep 17 00:00:00 2001 From: Angelo Genovese Date: Tue, 2 Dec 2025 16:30:09 -0500 Subject: [PATCH 1/3] [CU-86b7p1xgv] Add --local-federated flag to bypass Explorer federation bottleneck MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When concurrent requests to federated questions overwhelm the Explorer service, circuit breakers and connection timeouts cause failures. This happens because Explorer's federation layer becomes a bottleneck when coordinating responses from multiple publishers with queuing systems. This change adds a --local-federated flag that queries each collection directly in parallel, bypassing the Explorer federation layer. This allows workloads to proceed while the long-term solution (converting Explorer's federated API to use Data Connect-style streaming responses) is implemented. The flag maintains full compatibility with existing behavior and output format, making it a safe workaround for high-concurrency scenarios. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- .../commands/explorer/questions/commands.py | 29 ++- dnastack/client/explorer/client.py | 198 +++++++++++++++++- 2 files changed, 219 insertions(+), 8 deletions(-) diff --git a/dnastack/cli/commands/explorer/questions/commands.py b/dnastack/cli/commands/explorer/questions/commands.py index eb2317a5..9e79b0fe 100644 --- a/dnastack/cli/commands/explorer/questions/commands.py +++ b/dnastack/cli/commands/explorer/questions/commands.py @@ -102,6 +102,13 @@ def describe_question(question_id: str, output: str, context: Optional[str], end arg_names=['--output-file'], help='Output file path for results' ), + ArgumentSpec( + name='local_federated', + arg_names=['--local-federated'], + help='Query collections directly via local federation instead of using server-side federation', + type=bool, + default=False + ), DATA_OUTPUT_ARG, CONTEXT_ARG, SINGLE_ENDPOINT_ID_ARG, @@ -112,6 +119,7 @@ def ask_question( args: tuple, collections: Optional[JsonLike], output_file: Optional[str], + local_federated: bool, output: str, context: Optional[str], endpoint_id: Optional[str] @@ -119,6 +127,7 @@ def ask_question( """Ask a federated question with the provided parameters""" trace = Span() client = get_explorer_client(context=context, endpoint_id=endpoint_id, trace=trace) + # Parse collections if provided if collections: @@ -162,12 +171,20 @@ def ask_question( collection_ids = [col.id for col in question.collections] # Execute the question - results_iter = client.ask_federated_question( - question_id=question_name, - inputs=inputs, - collections=collection_ids, - trace=trace - ) + if local_federated: + results_iter = client.ask_question_local_federated( + federated_question_id=question_name, + inputs=inputs, + collections=collection_ids, + trace=trace + ) + else: + results_iter = client.ask_federated_question( + question_id=question_name, + inputs=inputs, + collections=collection_ids, + trace=trace + ) # Collect results results = list(results_iter) diff --git a/dnastack/client/explorer/client.py b/dnastack/client/explorer/client.py index cf90fe24..51e77867 100644 --- a/dnastack/client/explorer/client.py +++ b/dnastack/client/explorer/client.py @@ -1,4 +1,6 @@ from typing import List, Optional, Dict, Any, TYPE_CHECKING +from concurrent.futures import ThreadPoolExecutor, as_completed +import time if TYPE_CHECKING: from dnastack.client.explorer.models import FederatedQuestion @@ -10,7 +12,8 @@ from dnastack.client.explorer.models import ( FederatedQuestion, FederatedQuestionListResponse, - FederatedQuestionQueryRequest + FederatedQuestionQueryRequest, + QuestionCollection ) from dnastack.client.result_iterator import ResultLoader, InactiveLoaderError, ResultIterator from dnastack.client.service_registry.models import ServiceType @@ -136,6 +139,55 @@ def ask_federated_question( ) ) + def ask_question_local_federated( + self, + federated_question_id: str, + inputs: Dict[str, str], + collections: Optional[List[str]] = None, + trace: Optional[Span] = None + ) -> 'ResultIterator[Dict[str, Any]]': + """ + Query collections directly via local federation instead of server-side federation. + + Args: + federated_question_id: The ID of the federated question to ask + inputs: Dictionary of parameter name -> value mappings + collections: Optional list of collection IDs to query.

This is critical because Data Connect APIs return empty pages with next_page_url links until data is ready, then continue pagination until all results are delivered. This fix implements proper pagination handling by: - Making the initial POST request to start the query - Following next_page_url links with GET requests until exhausted - Aggregating all data across all pages before returning - Preventing infinite loops by tracking visited URLs Without this fix, users would get incomplete results when querying collections that return paginated responses, making the --local-federated flag unreliable for production use. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- dnastack/client/explorer/client.py | 66 ++++++++++++++++++++++++------ 1 file changed, 54 insertions(+), 12 deletions(-) diff --git a/dnastack/client/explorer/client.py b/dnastack/client/explorer/client.py index 51e77867..8f97b310 100644 --- a/dnastack/client/explorer/client.py +++ b/dnastack/client/explorer/client.py @@ -352,40 +352,82 @@ def load(self) -> List[Dict[str, Any]]: def _query_single_collection(self, collection: QuestionCollection) -> Dict[str, Any]: """ Query a single collection and return the result in federated format. + Handles Data Connect pagination by following next_page_url links.
