Why teams connect Google Cloud Spanner and Openai

Sync the records in Google Cloud Spanner 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 Google Cloud Spanner, so Google Cloud Spanner 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. Google Cloud Spanner 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 Google Cloud Spanner it describes are two halves of the same thing, and they drift the moment one is updated without the other.

Stacksync syncs Secondary indexes, Change streams, Views, Databases in Google Cloud Spanner with Batch jobs, Vector stores, Usage & Costs, Projects & Members in Openai in real time. Rows created or changed in Google Cloud Spanner 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 Google Cloud Spanner, 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 Google Cloud Spanner 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 Pull Administration Usage and Costs into a warehouse for FinOps chargeback, per-project budget tracking, and spend-tier planning.
  • 02 Mirror organization Projects, members, and service accounts into a database as an auditable access inventory for security reviews.
  • 03 Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.
  • 04 Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.

Common sync patterns

One record, one identifier

Each item in Openai carries the key of the row in Google Cloud Spanner it came from, so results resolve back to the exact record with nothing orphaned or duplicated.

Run the AI on current data

Rows created or changed in Google Cloud Spanner 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 Google Cloud Spanner, next to the source data your applications already query.

What you can sync between Google Cloud Spanner 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.

Google Cloud Spanner objects Openai objects How this pairing syncs
Secondary indexes Used to make incremental read queries efficient on non-key columns. 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. Secondary indexes is specific to Google Cloud Spanner and Models to Openai — each maps to any object or custom field on the other side.
Change streams Capture inserts, updates, and deletes for log-style change data capture. 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. Change streams is specific to Google Cloud Spanner and Fine-tuning jobs to Openai — each maps to any object or custom field on the other side.
Views Read-only projections useful for shaping data before it leaves Spanner. 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. Views is specific to Google Cloud Spanner and Files to Openai — each maps to any object or custom field on the other side.
Databases Top-level containers that scope schema and sync configuration. 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. Databases is specific to Google Cloud Spanner and Batch jobs to Openai — each maps to any object or custom field on the other side.
Tables Relational tables mapped one-to-one to sync targets. Vector stores File collections backing file-search retrieval, with name, file counts, usage bytes, and status; read as a metadata inventory of retrieval assets. Tables is specific to Google Cloud Spanner and Vector stores to Openai — each maps to any object or custom field on the other side.
Rows The unit of read and write in each sync cycle, keyed by primary key. Usage & Costs Per-model and per-project token, request, and dollar figures from the Administration Usage and Costs endpoints, read for FinOps chargeback and spend reporting. Rows is specific to Google Cloud Spanner and Usage & Costs to Openai — each maps to any object or custom field on the other side.

How changes propagate between Google Cloud Spanner 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.

Google Cloud Spanner Openai Sub-second propagation

DetectionChanges in Google Cloud Spanner are captured at the source via change data capture — no polling loop against its API. Change streams (log-style CDC), or timestamp-based polling queries.

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 Google Cloud Spanner records.

Openai Google Cloud Spanner 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 Google Cloud Spanner as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.
  • 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.
