Why teams connect ClickHouse and D2l Brightspace

Land the people and organization records from D2l Brightspace in ClickHouse as live tables for workforce reporting, without extract jobs, and write computed results back where D2l Brightspace can use them.

Workforce data is some of the most requested data in the warehouse and some of the most awkward to move: the record types are many, the fields carry sensitive personal information, the APIs are strict, and hand-built extract jobs go stale or break quietly. Whether D2l Brightspace is the system of record for employees and payroll, for candidates and applications, or for learners and course completions, the reporting belongs in ClickHouse next to everything else the company measures.

Stacksync syncs Assignments (Dropbox), Groups and Sections, Users, Enrollments from D2l Brightspace into tables in ClickHouse continuously, handling API limits and schema drift as they come. The connection is bi-directional, so values computed in ClickHouse, such as headcount rollups, cost allocations, or attrition risk flags, can be written back to fields in D2l Brightspace where the HR team acts on them. You configure which records and fields cross over, and in which direction, instead of maintaining pipeline code.

Common use cases

  • 01 Consolidate logs and business records from multiple sources into MergeTree tables for retention and reporting.
  • 02 Land product event data alongside synced CRM accounts so analysts join usage and revenue in one place.
  • 03 Pull Content user progress and Quiz attempt results into a Postgres warehouse for engagement and completion analytics.
  • 04 Sync Assignment (Dropbox) submissions and feedback into a reporting database or downstream review tool.

Common sync patterns

Queryable history for planning and audit

A continuously synced copy in ClickHouse gives you a durable, queryable record of how D2l Brightspace's records change over time, for headcount planning and audit questions.

Write-back of computed values

Segments, rollups, or risk flags computed in ClickHouse sync back onto the matching records in D2l Brightspace, where the HR team sees them in the system they already use.

HR data in the warehouse, minus the pipeline

People and organization records from D2l Brightspace arrive in ClickHouse as queryable tables, current within seconds instead of a day behind, replacing hand-built extract jobs.

What you can sync between ClickHouse and D2l Brightspace

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 D2l Brightspace objects How this pairing syncs
Materialized views Insert-time transformations that reshape incoming synced rows into aggregates. Assignments (Dropbox) Dropbox folders, submissions, and feedback; submission and evaluation data is read into reporting systems and feedback can be written back. Materialized views is specific to ClickHouse and Assignments (Dropbox) to D2l Brightspace — each maps to any object or custom field on the other side.
Distributed tables Query-routing tables over cluster shards in self-managed deployments. Groups and Sections Group categories, groups, and section membership within an org unit; enrollments are read and written to keep cohort assignments aligned. Distributed tables is specific to ClickHouse and Groups and Sections to D2l Brightspace — 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. Users User accounts in the Learning Platform (lp) component; created, read, updated, and deleted through the Valence API and typically synced two-way with an SIS or HRIS. Dictionaries is specific to ClickHouse and Users to D2l Brightspace — 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. Enrollments Links between Users and Org Units; enroll/unenroll and batch-enrollment routes let rosters be written from an upstream system and read back for reporting. Tables (MergeTree family) is specific to ClickHouse and Enrollments to D2l Brightspace — each maps to any object or custom field on the other side.
Databases Namespaces that group tables and scope permissions for sync users. Org Units The org structure — course offerings, sections, departments, and semesters; read for hierarchy and created/updated to provision courses from a database. Databases is specific to ClickHouse and Org Units to D2l Brightspace — each maps to any object or custom field on the other side.
Views Saved queries used as curated, read-only sync sources. Grades Grade objects, categories, schemes, and per-user grade values in the Learning Environment (le) component; values can be read out and written back onto the gradebook. Views is specific to ClickHouse and Grades to D2l Brightspace — each maps to any object or custom field on the other side.

How changes propagate between ClickHouse and D2l Brightspace

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 D2l Brightspace 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 D2l Brightspace through its API, with automatic retries and rate-limit backoff.

D2l Brightspace ClickHouse Sub-second propagation

DetectionD2l Brightspace notifies Stacksync of record changes through webhook events. Polling Valence endpoints with date/bookmark filters, differential Brightspace Data Sets (BDS) bulk exports for changed rows via the Data Hub, and.

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

Rate-limit considerations

  • D2l Brightspace: Per-caller token-bucket credit scheme; each route costs credits, responses carry X-Rate-Limit-Remaining, and over-quota calls return HTTP 429. D2L can adjust per-route credit costs.
