Why teams connect ClickHouse and GitHub

Get the data locked inside GitHub into ClickHouse as live tables, and send results back where GitHub can use them, without writing a pipeline.

Whatever GitHub is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Organizations and Teams, Users, Labels and Milestones, Repositories from GitHub into tables in ClickHouse continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in ClickHouse can also be written back into fields in GitHub where the tool can use them.

Common use cases

  • 01 Publish release data into customer-communication tools when a new version ships.
  • 02 Two-way sync of GitHub issues with Jira, Linear, or a support system so engineering and customer-facing teams work in their own tools.
  • 03 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • 04 Sync aggregated ClickHouse query results back into operational tools, such as account-level usage metrics into a CRM.

Common sync patterns

Cross-tool reporting

Combine GitHub's data with data from every other synced system to answer questions no single tool can.

Where GitHub accepts updates: operational write-back

Segments, scores, or reference values computed in ClickHouse sync back onto records in GitHub, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in ClickHouse preserves a queryable record even as data ages out of GitHub or gets changed inside it.

What you can sync between ClickHouse and GitHub

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

ClickHouse objects GitHub objects How this pairing syncs
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Pull Requests Review state, status checks, and merge status feed engineering dashboards and workflow tools. Distributed tables is specific to ClickHouse and Pull Requests to GitHub — each maps to any object or custom field on the other side.
Dictionaries In-memory lookup structures refreshed from external sources, sometimes fed by syncs. Commits Read-only history used to link code activity to tickets and releases. Dictionaries is specific to ClickHouse and Commits to GitHub — each maps to any object or custom field on the other side.
Tables (MergeTree family) Columnar, append-optimized tables that serve as the destination for high-volume sync loads. Releases Tagged versions synced into changelogs, CRMs, or customer-notification systems. Tables (MergeTree family) is specific to ClickHouse and Releases to GitHub — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Workflow runs (Actions) CI results synced into incident and reporting systems. Databases is specific to ClickHouse and Workflow runs (Actions) to GitHub — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. Organizations and Teams Membership data synced with identity systems and HR directories for access reviews. Views is specific to ClickHouse and Organizations and Teams to GitHub — each maps to any object or custom field on the other side.
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Users Author and assignee identities matched to internal directories. Materialized views is specific to ClickHouse and Users to GitHub — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and GitHub

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

ClickHouse GitHub Interval-based propagation

DetectionStacksync polls ClickHouse for changes on an incremental schedule, reading only records changed since the previous pass. No log-based CDC for consumers.

DeliveryEach detected change is written to GitHub through its API, with automatic retries and rate-limit backoff.

GitHub ClickHouse Sub-second propagation

DetectionGitHub notifies Stacksync of record changes through webhook events. Webhooks with a broad event catalog covering issues, pull requests, pushes, and releases.

DeliveryEach detected change is applied to ClickHouse as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • GitHub: Authenticated REST requests are limited to 5,000 per hour per user; GitHub Apps scale limits per installation.
