SiriusHelper: An LLM Agent-Based Operations Assistant for Big Data Platforms
Pith reviewed 2026-05-09 21:03 UTC · model grok-4.3
The pith
SiriusHelper deploys an LLM agent that routes user queries, performs multi-hop retrieval via a hierarchical knowledge base, and distills SOPs from tickets to reduce big data platform support volume by 20.8 percent.
A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.
Core claim
SiriusHelper acts as a unified online assistant that identifies user intent and routes queries to appropriate handling paths, including expert workflows for domain-specific cases like SQL execution diagnosis. It combines a DeepSearch-driven mechanism with a priority-based hierarchical knowledge base to support multi-hop retrieval without context overload. The system also performs automated ticket understanding to diagnose failure reasons and extract domain-specific SOPs that continuously enrich the knowledge base, resulting in better performance than alternatives and a measured 20.8 percent drop in online ticket volume during deployment on the Tencent Big Data platform.
What carries the argument
The DeepSearch-driven mechanism paired with a priority-based hierarchical knowledge base for multi-hop retrieval, together with automated ticket understanding and SOP distillation that diagnoses failures and adds reusable procedures back into the system.
If this is right
- The assistant outperforms representative alternatives in both offline experiments and live use.
- Online ticket volume drops by 20.8 percent once the system is active.
- Both broad consultation and specialized troubleshooting workflows receive dedicated handling paths.
- Escalated tickets are converted into structured SOPs that improve the knowledge base over time.
- Answer reliability rises and response latency falls for complex queries that require several retrieval steps.
Where Pith is reading between the lines
- The same routing-plus-hierarchical-retrieval pattern could transfer to other enterprise platforms that face similar general-versus-specialized query mixes.
- If ticket distillation works reliably, the volume of human expert involvement in support loops should continue to decline as the knowledge base matures.
- Extending the priority hierarchy to include temporal or usage-based weighting might further improve retrieval precision in rapidly changing data environments.
- Teams running large-scale data services could test whether replacing flat RAG indexes with this hierarchical approach yields comparable ticket reductions outside the original deployment setting.
Load-bearing premise
The DeepSearch mechanism with the hierarchical knowledge base will consistently deliver accurate multi-hop results without overwhelming context, and the automated analysis of tickets will correctly identify missing knowledge or routing errors to produce useful SOPs.
What would settle it
A controlled deployment in which multi-hop troubleshooting queries continue to produce incomplete or slow answers or in which ticket analysis yields no new reusable SOPs, so that ticket volume shows no measurable reduction after rollout.

read the original abstract
Big data platforms are widely used in modern enterprises, and an in-production intelligent assistant is increasingly important to help users quickly find actionable guidance and reduce operational burden. While recent LLM+RAG assistants provide a natural interface, they face practical challenges in real deployments: limited scenario coverage across both general consultation and domain-specific troubleshooting workflows, inefficient knowledge access due to inadequate multi-hop retrieval and flat knowledge organization, and high maintenance cost because escalated tickets are unstructured and hard to convert into assistant improvements and reusable SOPs. In this paper, we present SiriusHelper, a deployed intelligent assistant for big data platforms. SiriusHelper serves as a unified online assistant that automatically identifies user intent and routes queries to the right handling path, including dedicated expert workflows for specialized scenarios (e.g., SQL execution diagnosis). To support complex troubleshooting, SiriusHelper combines a DeepSearch-driven mechanism with a priority-based hierarchical knowledge base to enable multi-hop retrieval without context overload, thus improving answer reliability and latency. To reduce expert overhead, SiriusHelper further introduces automated ticket understanding and SOP distillation: it diagnoses the assistant failure reason (e.g., missing knowledge or wrong routing) and extracts domain-specific SOPs to continuously enrich the knowledge base. Experiments and online deployment on Tencent Big Data platform show that SiriusHelper outperforms representative alternatives and reduces online ticket volume by 20.8\%.

Referee Report
Summary. The paper presents SiriusHelper, an LLM agent-based operations assistant for big data platforms. It automatically identifies user intent and routes queries to appropriate handling paths including expert workflows, combines a DeepSearch-driven mechanism with a priority-based hierarchical knowledge base for multi-hop retrieval, and introduces automated ticket understanding to diagnose failure reasons and distill SOPs for continuous KB enrichment. Experiments and online deployment on the Tencent Big Data platform are claimed to show outperformance over representative alternatives and a 20.8% reduction in online ticket volume.
Significance. If the empirical deployment outcomes hold under scrutiny, the work could have practical significance for applied LLM systems in enterprise big data operations by addressing scenario coverage, multi-hop knowledge access, and maintenance costs through a self-improving mechanism. The real-world deployment and ticket reduction result, if substantiated with proper controls, would provide valuable evidence of impact beyond synthetic benchmarks.
major comments (2)
- Abstract: The central claims of outperformance over alternatives and a 20.8% reduction in online ticket volume are presented without experimental details, baseline definitions, metric definitions, or statistical tests, preventing verification of the data-to-claim linkage for the headline result.
- Abstract: The automated ticket understanding and SOP distillation mechanism is described as diagnosing failure reasons (e.g., missing knowledge or wrong routing) and enriching the KB, but no quantitative validation of diagnosis precision, error analysis on extracted SOPs, or ablation studies showing the enrichment step improves retrieval quality are supplied; this is load-bearing for the self-improvement loop and the attributed ticket reduction.
minor comments (1)
- The abstract could more explicitly define key terms such as 'DeepSearch-driven mechanism' and 'priority-based hierarchical knowledge base' to improve accessibility for readers unfamiliar with the specific implementation.

Referee: Abstract: The central claims of outperformance over alternatives and a 20.8% reduction in online ticket volume are presented without experimental details, baseline definitions, metric definitions, or statistical tests, preventing verification of the data-to-claim linkage for the headline result.
Authors: We agree the abstract is concise by design. The full experimental details—including baseline definitions (vanilla LLM, standard RAG, and other agent baselines), metrics (accuracy, latency, retrieval F1, and ticket volume), and statistical tests (paired t-tests with p-values reported)—appear in Section 5 (Experiments) and the online deployment subsection. The 20.8% reduction comes from a controlled production A/B test on the Tencent platform. To improve standalone readability of the abstract, we will add one sentence summarizing the evaluation methodology and explicitly directing readers to Section 5. revision: yes

Authors: The primary evidence for the self-improvement loop is the measured 20.8% ticket-volume reduction in the live deployment, which occurred after the SOP-distillation component was activated and directly addressed diagnosed gaps (missing knowledge or routing errors). We acknowledge that dedicated quantitative validation—diagnosis precision on annotated tickets, error analysis of extracted SOPs, and an ablation isolating the enrichment step—would strengthen the claim. We will add these analyses (including a new ablation table) to the revised Experiments section. revision: yes
Circularity Check
No derivational circularity; purely empirical system evaluation
full rationale
The paper describes an LLM-based assistant architecture (DeepSearch + hierarchical KB + automated ticket understanding) and supports its claims exclusively via deployment metrics on Tencent's platform, including a reported 20.8% ticket reduction. No equations, first-principles derivations, fitted parameters renamed as predictions, or uniqueness theorems appear in the provided text. All load-bearing assertions reduce to observed outcomes rather than self-referential definitions or self-citation chains, rendering the evaluation self-contained against external benchmarks.
