Why teams connect Azure Service Bus and Google Cloud Spanner

Keep Google Cloud Spanner and Azure Service Bus in step: the rows in your database and the Dead-letter queue, Scheduled / deferred messages, Queues, Topics your engineering tools track stay consistent in real time, in both directions.

Google Cloud Spanner is where your application's durable data lives; Azure Service Bus is where engineering and operations teams track the issues, events, messages, or identities that run alongside it. The two overlap constantly, a row should open a ticket, an alert should land as a record, a user in one should exist in the other, but bridging them today means per-tool integration code: auth, webhooks, pagination, rate limits, and retries, built and maintained separately for every tool.

Stacksync syncs Change streams, Views, Databases, Tables in Google Cloud Spanner with Dead-letter queue, Scheduled / deferred messages, Queues, Topics in Azure Service Bus field by field, in real time, and in both directions. You decide which system owns which fields; Stacksync keeps every copy consistent and resolves conflicts by rules you set, so the database and the tooling around it never drift apart.

Common use cases

  • 01 Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.
  • 02 Consolidate data from a globally distributed Spanner deployment into regional business systems.
  • 03 Bridge order or workflow events off a subscription into an ERP or ticketing system as they arrive, mapping message properties and the payload to target fields.
  • 04 Preserve per-account or per-order processing order by grouping related messages into a session so a single consumer handles them in FIFO sequence.

Common sync patterns

One integration pattern instead of per-tool API code

Read and write the synced tables in Google Cloud Spanner and Stacksync keeps Azure Service Bus current, replacing the auth, webhooks, rate limits, and retry logic you would otherwise maintain for each tool.

React to changes on either side in near real time

Updates in Azure Service Bus arrive as row changes in Google Cloud Spanner, and writes to Google Cloud Spanner propagate to Azure Service Bus within seconds, so triggers, jobs, and alerts fire without polling.

Where Azure Service Bus manages users or groups: keep identity aligned

Directory and identity records in Azure Service Bus stay matched to the users or owners table in Google Cloud Spanner, so provisioning and de-provisioning flow from one source.

What you can sync between Azure Service Bus and Google Cloud Spanner

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 Service Bus objects Google Cloud Spanner objects How this pairing syncs
Sessions Message sessions group related messages by SessionId so one consumer handles them in FIFO order; the way ordered processing is achieved in Service Bus. Interleaved tables Child rows physically co-located with parents; synced as related records. Sessions is specific to Azure Service Bus and Interleaved tables to Google Cloud Spanner — each maps to any object or custom field on the other side.
Dead-letter queue A sub-queue on every queue and subscription that automatically holds messages exceeding the max delivery count or their TTL, read for inspection and reprocessing. Secondary indexes Used to make incremental read queries efficient on non-key columns. Dead-letter queue is specific to Azure Service Bus and Secondary indexes to Google Cloud Spanner — each maps to any object or custom field on the other side.
Scheduled / deferred messages Messages enqueued for future delivery at a set time, or deferred and set aside by sequence number for retrieval later, out of the normal receive order. Change streams Capture inserts, updates, and deletes for log-style change data capture. Scheduled / deferred messages is specific to Azure Service Bus and Change streams to Google Cloud Spanner — each maps to any object or custom field on the other side.
Queues Point-to-point entity: a sender writes messages and one competing consumer at a time receives them under PeekLock, then completes or abandons each message. Views Read-only projections useful for shaping data before it leaves Spanner. Queues is specific to Azure Service Bus and Views to Google Cloud Spanner — each maps to any object or custom field on the other side.
Topics Publish/subscribe entity a publisher sends to; each message is fanned out to every subscription whose filter rules match, so many consumers get their own copy. Databases Top-level containers that scope schema and sync configuration. Topics is specific to Azure Service Bus and Databases to Google Cloud Spanner — each maps to any object or custom field on the other side.
Subscriptions A virtual queue attached to a topic; a consumer receives its own stream of matching messages here, independent of other subscriptions on the same topic. Tables Relational tables mapped one-to-one to sync targets. Subscriptions is specific to Azure Service Bus and Tables to Google Cloud Spanner — each maps to any object or custom field on the other side.

How changes propagate between Azure Service Bus and Google Cloud Spanner

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 Service Bus Google Cloud Spanner Interval-based propagation

DetectionStacksync polls Azure Service Bus for changes on an incremental schedule, reading only records changed since the previous pass. Consumes messages as they arrive: an AMQP receiver holds an open connection and takes messages with PeekLock (lock, then complete/abandon) or.

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

Google Cloud Spanner Azure Service Bus 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.

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

Rate-limit considerations

  • Azure Service Bus: Standard tier throttles around 1,000 operations/second and returns a ServerBusy error; Premium provisions dedicated messaging units (1, 2, 4, 8, or 16) for isolated, predictable throughput. Up to 5,000 concurrent AMQP connections per namespace and 5,000 concurrent receive requests per entity.
  • Google Cloud Spanner: Throughput is bounded by the instance's provisioned compute capacity rather than a fixed API quota.

How the Azure Service Bus and Google Cloud Spanner connectors work

Azure Service Bus

Integration surface
AMQP 1.0 messaging protocol plus an HTTP/REST API; entities live under a namespace at <namespace>.servicebus.windows.net (legacy SBMP also supported)
Authentication
Microsoft Entra ID (Azure AD) RBAC with managed identities - roles Azure Service Bus Data Owner, Data Sender, and Data Receiver - or Shared Access Signature (SAS) policies scoped with Manage, Send, and Listen claims
Change detection
Consumes messages as they arrive: an AMQP receiver holds an open connection and takes messages with PeekLock (lock, then complete/abandon) or ReceiveAndDelete. No modified-date polling and no native HTTP push; Azure Event Grid can separately raise an 'active messages available' event for intermittent receivers
