Why teams connect Azure Cosmos DB and Openai

Sync the records in Azure Cosmos DB into Openai and land its embeddings, classifications, and generated fields back on the same rows, in real time and without a pipeline to maintain.

Openai is a read-only source: Stacksync reads its data in real time and delivers it into Azure Cosmos DB, so Azure Cosmos DB always reflects the current state of Openai — without exports, scripts, or schedulers.

AI systems do not hold customers or invoices the way business apps do. What they hold is derived from your data: the vectors and metadata in a vector store, or the classifications, extracted fields, and generated text a model produces over records it was given. Azure Cosmos DB is where those source records actually live. The bridge between the two is the row itself, since an item in Openai and the record in Azure Cosmos DB it describes are two halves of the same thing, and they drift the moment one is updated without the other.

Stacksync syncs Stored procedures and triggers, Databases, Containers, Items (JSON documents) in Azure Cosmos DB with Fine-tuning jobs, Files, Batch jobs, Vector stores in Openai in real time. Rows created or changed in Azure Cosmos DB flow into Openai so inference and embedding run on current data, and the scores, labels, and generated fields Openai produces flow back onto the matching rows in Azure Cosmos DB, mapped field by field. A change on either side appears on the other within seconds, with no extraction job or webhook plumbing to keep alive.

Because matching is by a stable identifier, every row in Azure Cosmos DB stays tied to its AI-side counterpart in Openai. Retrieval, enrichment, and generated content always resolve back to the record they came from, so there are no orphaned vectors and no labels describing a version of a row that no longer exists.

Common use cases

  • 01 Subscribe to batch.completed and fine_tuning.job.succeeded webhooks so a downstream pipeline step fires the moment an offline-inference or training job finishes.
  • 02 Pull Administration Usage and Costs into a warehouse for FinOps chargeback, per-project budget tracking, and spend-tier planning.
  • 03 Mirror Cosmos DB items into Postgres so teams can query operational data with standard SQL.
  • 04 Two-way sync between a Cosmos DB-backed product catalog and a PIM or commerce platform.

Common sync patterns

Run the AI on current data

Rows created or changed in Azure Cosmos DB flow into Openai as they happen, so embeddings, classifications, and prompts run on the latest records instead of a nightly snapshot.

Write results back onto the record

Scores, labels, extracted fields, or generated text produced in Openai land on the matching row in Azure Cosmos DB, next to the source data your applications already query.

Keep derived data fresh as sources change

When a row in Azure Cosmos DB is updated or removed, its counterpart in Openai is updated or removed too, so nothing in Openai describes a record that has since changed or gone.

What you can sync between Azure Cosmos DB and Openai

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.

Azure Cosmos DB objects Openai objects How this pairing syncs
Change feed entries Ordered record of inserts and updates per partition, consumed for incremental sync. Audit logs Organization audit-log events (API-key changes, logins, project edits) from the Administration API; read for compliance and security monitoring. Change feed entries is specific to Azure Cosmos DB and Audit logs to Openai — each maps to any object or custom field on the other side.
Stored procedures and triggers Server-side logic scoped to a partition; relevant when writes must respect existing validation. Models Catalog of available base, snapshot, and fine-tuned models with owner and capabilities; read-only reference data used to resolve inference and fine-tuning targets. Stored procedures and triggers is specific to Azure Cosmos DB and Models to Openai — each maps to any object or custom field on the other side.
Databases Top-level namespaces that scope containers and throughput provisioning. Fine-tuning jobs Training jobs with status, base model, hyperparameters, trained-model name, and result files; status received by webhook or polled from queued through succeeded or failed. Databases is specific to Azure Cosmos DB and Fine-tuning jobs to Openai — each maps to any object or custom field on the other side.
Containers The unit of partitioning and throughput; each container maps to a synced collection. Files Uploaded training, validation, and batch-input files plus generated output files; listed and read by ID, not written back as business records in sync. Containers is specific to Azure Cosmos DB and Files to Openai — each maps to any object or custom field on the other side.
Items (JSON documents) Schema-flexible JSON records read and written during sync; nested structures are flattened or mapped as needed. Batch jobs Asynchronous bulk-inference jobs within a 24-hour window, with status and output/error file IDs; completion detected by the batch.completed webhook or by polling. Items (JSON documents) is specific to Azure Cosmos DB and Batch jobs to Openai — each maps to any object or custom field on the other side.
Partition keys Determine data distribution and must be included on writes for the sync to route items correctly. Vector stores File collections backing file-search retrieval, with name, file counts, usage bytes, and status; read as a metadata inventory of retrieval assets. Partition keys is specific to Azure Cosmos DB and Vector stores to Openai — each maps to any object or custom field on the other side.

How changes propagate between Azure Cosmos DB and Openai

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.

Azure Cosmos DB Openai Sub-second propagation

DetectionChanges in Azure Cosmos DB are captured at the source via change data capture — no polling loop against its API. Built-in change feed exposing inserts and updates in order within each partition key range.

DeliveryOpenai does not accept inbound record writes, so this direction carries requests rather than records: Openai's output flows back as field updates on the originating Azure Cosmos DB records.

Openai Azure Cosmos DB Sub-second propagation

DetectionOpenai notifies Stacksync of record changes through webhook events. Push webhooks (Standard Webhooks spec, whsec_ signing secret) fire on batch.completed, fine_tuning.job.succeeded/failed, response.completed/failed,.

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

Rate-limit considerations

  • Openai: Rate limits are set per organization and per project as RPM/RPD and TPM/TPD and rise across five spend-based usage tiers; responses carry x-ratelimit-remaining headers and return HTTP 429 on breach.
