Comprehensive Analysis of Server-Side Work This Week for Epic: Knowledge Graph First Iteration (gitlab-org&17514)

This report provides a comprehensive analysis of server-side work related to the epic https://gitlab.com/groups/gitlab-org/-/epics/17514 (Knowledge Graph First Iteration), with a specific focus on activities identified as occurring "this week" (approximately the week of May 10th - May 17th, 2025, based on the latest timestamps in the provided research findings).

Overall Summary of Server-Side Work This Week

The provided research findings indicate that detailed information about specific, completed server-side work "this week" is largely unavailable for most items related to Epic gitlab-org&17514. Many individual analysis reports explicitly state this limitation.

However, some activities and status updates related to ongoing server-side development and foundational setup were noted for "this week":

POC for Go Package for gitlab-code-parser (gitlab-org/gitlab#536081): An async update on 2025-05-16 confirmed this task is "In development," with plans to resume active work. This involves creating Go bindings for the Rust-based gitlab-code-parser for server-side consumption.
gitlab-code-parser Project Setup (gitlab-org/gitlab#536077): The issue tracking the creation of the gitlab-code-parser Rust project saw updates on 2025-05-13 and 2025-05-14. Related Merge Requests for workspace setup and unit test reporting (gitlab-org/rust/gitlab-code-parser!4, gitlab-org/rust/gitlab-code-parser!8) are foundational for this server-consumed library. Activity on these MRs this week would constitute server-side progress.
Project Security for Knowledge Graph Rust Projects (gitlab-org/gitlab#540414): This issue, ensuring security best practices for new Rust projects like knowledge-graph and gitlab-code-parser, was updated on 2025-05-15. While some settings are marked complete, it's unclear from the findings if these completions occurred "this week" or earlier.

Beyond these specific points, the majority of the server-side work detailed in the research findings pertains to planned architecture, requirements, and tasks rather than concrete implementations completed "this week."

Detailed Analysis of Server-Side Activities This Week (Where Information Exists)

The following section details the items where some activity or status update related to server-side work was noted for "this week."

1. `gitlab-org/gitlab#536081`: [Gitlab Code Parser] Create POC for publishing a Go package for the parser

Server-Side Relevance:

This task is crucial for server-side integration of the gitlab-code-parser (a Rust library).
The goal is to create a Go package (via FFI/CGO) so that Go-based server-side applications, such as the embeddings indexer, can utilize the parser.

Previous discussions (from late April/early May, not "this week") explored technical approaches, including replicating Kuzu's method of publishing Go bindings (committing pre-compiled binaries per OS) and potentially creating a separate Go bindings project. The structure proposed by @dgruzd on 2025-05-06 was:

rust-go-bindings/
├── .gitlab-ci.yml
├── rust/                       # Rust library code
│   ├── Cargo.toml
│   └── src/
│       └── lib.rs
├── bindings/                   # Go bindings code

│   └── windows_amd64/
├── Makefile                    # Build targets for these platforms
├── go.mod
└── README.md

Summary for This Week: The work is confirmed as "In development" with plans to actively resume. This indicates ongoing server-side integration efforts for the core parsing library.

2. `gitlab-org/gitlab#536077`: Create GitLab Code Parser Project

Epic Link: gitlab-org&17516 (One Parser (gitlab-code-parser)), supporting gitlab-org&17514.
Activity This Week:
- The issue was updated on 2025-05-14T22:12:26Z.
- A comment regarding documentation labels was added on 2025-05-13T15:30:21Z:
```
I'm skipping the ~documentation + ~"Technical Writing" labels for now - I think there might be docs work later, but not yet.
```
Server-Side Relevance:
- This issue tracks the foundational setup of the gitlab-code-parser Rust project, which is a core server-side (and client-side) component for code analysis.
- The proposal includes creating a Cargo workspace, a minimal parser-core crate, repository hygiene (.gitignore, LICENSE.md, rust-toolchain.toml, mise.toml), and a README.md.
- Related Merge Requests (foundational server-side setup):
  - gitlab-org/rust/gitlab-code-parser!4: chore: init workspace
  - gitlab-org/rust/gitlab-code-parser!8: test: setup unit test reporting
- If these MRs saw active development, review, or merges "this week", they represent concrete server-side foundational work. The research findings state these are "likely the direct implementation work stemming from this issue's proposal."
Summary for This Week: Minor updates to the tracking issue were made. Significant server-side foundational work would be represented by progress on the linked MRs for the gitlab-code-parser project.

3. `gitlab-org/gitlab#540414`: Project Security (gitalisk, gitlab-code-parser, knowledge-graph)

Epic Link: gitlab-org&17514 (Knowledge Graph First Iteration).
Activity This Week:
- The issue was updated on 2025-05-15T01:16:03Z.
Server-Side Relevance:
- This issue aims to ensure security best practices are enabled for the new Rust projects underpinning the Knowledge Graph effort, including:
  - https://gitlab.com/gitlab-org/rust/knowledge-graph (server-side indexer/graph component)
  - https://gitlab.com/gitlab-org/rust/gitlab-code-parser (server-consumed parser)
  - https://gitlab.com/gitlab-org/rust/gitalisk (potential future server-side git operations, though primarily desktop-focused now)
- The issue description includes a table of security settings. For gitlab-code-parser and knowledge-graph, the following are marked as complete (:white_check_mark:):
  - protect main branch
  - Dependency Scanning
- These are important server-side project configurations.
Summary for This Week: The issue tracking security setup was updated. However, the research findings note: "The context does not contain details about specific server-side work completed this week beyond the issue being updated and the initial state described in the description and comments." This suggests the completed items might have been set up when the issue was created (2025-05-06) or shortly thereafter, not necessarily "this week."

Overview of Planned Server-Side Architecture and Work (Relevant to Epic `gitlab-org&17514`)

While specific "work done this week" is limited in the findings, a comprehensive analysis includes the significant planned server-side architecture and tasks for the Knowledge Graph First Iteration. This is primarily detailed under the gitlab-org&17518: Knowledge Graph Server epic and its children.

I. Knowledge Graph Server (`gitlab-org&17518`)

This epic is the direct child of gitlab-org&17514 and outlines the core server-side components.

Overall Server-Side Proposal:

Storage: Knowledge graphs for repositories will be stored in file-embedded Kuzu DBs (one DB per repository).
Graph Node Service: A thin API service will run on "graph nodes" (extended Zoekt nodes) to serve query requests and manage DB tasks.
Infrastructure Re-use: Existing Zoekt nodes and the gitlab-zoekt-indexer service will be extended for graph database indexing and querying, avoiding the need to build new infrastructure from scratch.
GitLab Rails Abstraction: An abstraction layer will be created in GitLab Rails to allow other services to query graph databases using the Cypher query language.

II. Creation/Update of Knowledge Graph for a Repository (`gitlab-org&17765`)

This child epic details the server-side orchestration for creating and updating graph databases.

A. GitLab Rails Responsibilities:

Repository State Maintenance: For each repository, Rails will maintain:
- The primary graph node.
- A list of current replicas.
- A list of desired replicas.
- A list of nodes from which the repository's graph should be removed.
Task Scheduling: Rails will schedule tasks for Graph nodes (e.g., "create graph," "copy graph").
Status Updates Reception: Rails will receive reports from Graph nodes upon task completion.
Replica Management: Based on status updates, Rails will update replica status in its database and schedule tasks for other replica nodes to copy data from the primary node.

B. Interaction with Graph Nodes:

Graph nodes (running an extended gitlab-zoekt-indexer) will periodically check GitLab Rails (via an Internal API) for tasks.
Tasks can be for initial parsing/creation or for syncing/copying an existing graph.

C. Sequence Diagram (Creation/Update & Replication):

sequenceDiagram
    box Rails
    participant A as Internal API
    participant W as Worker
    participant DB as Rails DB
    end
    box Graph node1
    participant G as Graph API
    participant P as Parser
    end
    box Graph node2
    participant G2 as Graph API
    end
    W->>DB: find primary node for repoX
    DB-->>W: node1
    W->>DB: create task for node1 to index repoX
    G->>A: GET (periodic check for DBs to parse)
    A-->>G: return task to index repoX
    G->>P: Parse repository (call parser library/CLI)
    P-->>G: Graph data
    G->>G: create new DB repoX.new
    G->>G: if repoX already exists, close connections to the repo
    G->>G: replace repoX with repoX.new
    G-->>A: OK
    A->>DB: update status/metadata in DB for replica and node
    G2->>A: GET (periodic check for DBs to sync)
    A-->>G2: return list of tuples (repo, source node): [repoX:node1]
    G2->>G: GET repoX
    G-->>G2: send repoX

D. Key Server-Side Issues:

gitlab-org/gitlab#540850: Add graph db scheduling logic (Rails).
gitlab-org/gitlab#540854: Add replication logic for graph DB (Rails).
gitlab-org/gitlab-zoekt-indexer#79: Extend graph-zoekt-indexer with "create graph" task (Graph Node/Zoekt Indexer).
gitlab-org/gitlab-zoekt-indexer#80: Add support to copy graph DB from other graph node (Graph Node/Zoekt Indexer).

III. Querying Knowledge Graph (`gitlab-org&17766`)

This child epic details the server-side architecture for querying the knowledge graph.

A. Server-Side Components:

GitLab Rails:
- Acts as the entry point for queries (e.g., from Duo Chat).
- Contains a "Knowledge graph layer" (abstraction/interface).
- Handles authentication and authorization.
- Finds the appropriate graph node.
- Sends Cypher query requests to the graph node.
- Processes responses.
Knowledge graph layer (within GitLab Rails):
- Accepts a Cypher query and project ID.
- Performs permission checks.
- Finds the primary node for the repository.
- Manages communication with the graph node.
zoekt-webservice (Graph API on Graph Nodes):
- Runs on graph nodes (extended gitlab-zoekt-indexer).
- Receives Cypher queries from the GitLab Rails "Knowledge graph layer."
- Interacts with Kuzu DB instances.
- Opens the relevant Kuzu DB (read-only for querying).
- Executes the Cypher query.
- Returns results to GitLab Rails.
Kuzu DB:
- The chosen graph database technology, supporting Cypher.
- Hosted on graph nodes.

B. Query Flow Diagrams:

Flowchart:

    GA2 -->K22[Kuzu DB C]
    GA2 -->K23[Kuzu DB D]
    end

Sequence Diagram:

sequenceDiagram
    box Rails
    participant T as Duo Chat Tool
    participant A as Knowledge graph layer
    participant DB as Rails DB
    end
    box Graph node1
    participant G as Graph API
    end
    T->>A: Cypher query on repoX
    A->>DB: find primary node for repoX
    DB-->>A: node1
    A->>G: GET (Cypher query for repoX)
    G->>G: open repoX DB if not yet opened
    G->>G: run Cypher query
    G-->>A: query result
    A-->>T: query result

C. Key Server-Side Requirements for Querying (Quotes from Epic):

"All requests to graph nodes should go through GitLab Rails which takes care of authentication (of end users) and authorization (checking if a user can access a repository)."
"Whoever can read project's repository should have access to the graph database for this repository."
"In GitLab Rails there will be a simple abstraction layer/interface which can be used to query knowledge graph for a repository. This layer will take care of permission checks, finding primary node for the repository and sending the request to the graph node and processing the response. As an input it will accept a cypher query and a project ID (on which we want to run the query)."
"Kuzu databases on graph nodes will be always opened in read-only mode for security reason..."
"There will be a maximum timeout set for running a Cypher query, e.g. 15s..."

D. Key Server-Side Issues:

gitlab-org/gitlab#541360: Create knowledge graph service/interface (Rails "Knowledge graph layer").
gitlab-org/gitlab-zoekt-indexer#81: Add "query graph DB" to gitlab-zoekt-indexer webservice (Graph Node/Zoekt Indexer).

IV. Graph Node Management (`gitlab-org&17767`)

This child epic focuses on adapting existing Zoekt infrastructure for graph nodes.

A. Core Idea (Quote from Epic):

We will use existing Zoekt nodes to index, store and serve also graph DBs. The major benefit is that we can re-use existing Zoekt logic (nodes management on Rails side) and infrastructure (deployment of Zoekt nodes) and node logic itself (Zoekt Webservice and Indexer).

B. Server-Side Implications (GitLab Rails):

Adapting existing Zoekt node management logic in Rails.
Modifying database models to distinguish node capabilities.
Adding new models for knowledge graph specific entities.

C. Class Diagram for Models (from gitlab-org/gitlab#540785):

classDiagram
    namespace ZoektModels {
    class Node
    class Index
    class Repository
    class Task
    class EnabledNamespace
    class Replica
    }
    namespace KnowledgeGraphModels {
    class KnowledgeGraphEnabledRepository
    class KnowledgeGraphReplica
    }

    Node "1" --&gt; "*" Task : has_many tasks
    Node "1" --&gt; "*" Index : has_many indices

    EnabledNamespace "1" --&gt; "*" Replica : has_many replicas

    Replica "1" --&gt; "*" Index : has_many indices

    Index "1" --&gt; "*" Repository : has_many repositories
    Repository "1" --&gt; "*" Task : has_many tasks

    KnowledgeGraphEnabledRepository "1" --&gt; "*" KnowledgeGraphReplica : has_many replicas
    KnowledgeGraphReplica "1" --&gt; "*" Task : has_many tasks
    Node "1" --&gt; "*" KnowledgeGraphReplica : has_many graph replicas

D. Key Server-Side Issues:

gitlab-org/gitlab#540844: Add monitoring and logging for graph DBs.
gitlab-org/gitlab#540786: Extend zoekt model with zoekt-only/graph-only setting (Rails DB model).
gitlab-org/gitlab#540785: Add knowledge graph models (Rails DB models).

V. Core Indexer and Parser (Related Epics `gitlab-org&17517` & `gitlab-org&17516`)

While detailed "this week" updates for these were older, their server-side role is critical for the Knowledge Graph:

gitlab-code-parser (gitlab-org&17516): A Rust-based universal code parser.
- Server-Side Consumption: Via FFI by Go-based indexers (like Embeddings) and directly as a Rust crate by the Knowledge Graph indexer.
- API: Planned to accept file path/content and return structured data (FQNs, node types, byte ranges). Parsing rules embedded within the library.
- Integration: Discussions around CLI vs. FFI for server-side invocation by Go workers, with FFI being the longer-term goal for performance. Batching API for FFI calls is a consideration.
Knowledge Graph Core Indexer (gitlab-org&17517): A Rust-based indexer that consumes gitlab-code-parser output.
- Initial Indexing: Rust indexer generates intermediate files (e.g., CSVs), which a Go worker uses for bulk import into KuzuDB.
- Incremental Updates: More complex; involves the Rust indexer library potentially interacting directly with a copy of the KuzuDB, managed by a server-side service.
- Server Role: Go workers (potentially on Zoekt nodes) orchestrate repository checkout, execution of the Rust indexer (CLI or FFI), and KuzuDB operations.

This planned architecture forms the backbone of the server-side work for the Knowledge Graph First Iteration. Future weekly reports would ideally capture more specific implementation progress against these plans.
