Why teams connect Azure Service Bus and Citus

Keep Citus 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.

Citus 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 Views, Sequences, Distributed tables, Reference tables in Citus 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 Consolidate per-tenant rows from distributed tables into per-customer reporting databases.
  • 02 Sync high-volume event or tenant data from a Citus cluster into a warehouse for cross-tenant analytics.
  • 03 Send new and changed database rows as messages to a Service Bus queue or topic so multiple downstream consumers process the change stream independently.
  • 04 Receive messages from a queue or subscription with an AMQP receiver and write them into a Postgres or warehouse table for durable, SQL-queryable storage.

Common sync patterns

Land tool activity as queryable rows

Records and events from Azure Service Bus arrive in Citus as rows, so tickets, alerts, messages, or identity changes become joinable data your services and reports read directly.

One integration pattern instead of per-tool API code

Read and write the synced tables in Citus 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 Citus, and writes to Citus propagate to Azure Service Bus within seconds, so triggers, jobs, and alerts fire without polling.

What you can sync between Azure Service Bus and Citus

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 Citus 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. Views Curated projections over distributed data, often used as read-only sync sources. Sessions is specific to Azure Service Bus and Views to Citus — 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. Sequences Key generators that matter when external writes must not collide with application inserts. Dead-letter queue is specific to Azure Service Bus and Sequences to Citus — 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. Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Scheduled / deferred messages is specific to Azure Service Bus and Distributed tables to Citus — 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. Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Queues is specific to Azure Service Bus and Reference tables to Citus — 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. Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Topics is specific to Azure Service Bus and Local tables to Citus — 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. Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Subscriptions is specific to Azure Service Bus and Schemas to Citus — each maps to any object or custom field on the other side.

How changes propagate between Azure Service Bus and Citus

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 Citus 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 Citus as a row-level write, with types converted between the two schemas.

Citus Azure Service Bus Sub-second propagation

DetectionChanges in Citus are captured at the source via change data capture — no polling loop against its API. PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres.

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.

How the Azure Service Bus and Citus 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
