Why teams connect Citus and E2 Shop System
Give your engineers E2 Shop System's data in Citus: read it with normal queries, write back through the sync, and skip the ERP API entirely.
E2 Shop System is a read-only source: Stacksync reads its data in real time and delivers it into Citus, so Citus always reflects the current state of E2 Shop System — without exports, scripts, or schedulers.
ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.
Stacksync mirrors Vendors, Parts, Routings / Operations, Purchase orders from E2 Shop System into Citus and keeps both sides consistent in real time. Whatever E2 Shop System is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in Citus sync back into E2 Shop System with its validations respected.
Common use cases
- Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.
- Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
- Land quote, job cost, and time-ticket data in a warehouse for margin analysis across jobs.
- Keep purchase order data visible to planning or supplier-facing tools without direct ERP access.
Where E2 Shop System is the HR system of record: people data for internal systems
Worker and org records stay current in Citus for provisioning, access, and reporting systems that read from the database.
Controlled write-back
Choose exactly which tables and fields may flow from Citus back into E2 Shop System, keeping the ERP authoritative.
Read ERP records with a query
Records from E2 Shop System live in Citus as ordinary tables or collections, joinable with the rest of your data.
What you can sync between Citus and E2 Shop System
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.
| Citus objects | E2 Shop System objects | |
|---|---|---|
| Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. | Time tickets Labor collection records used for job costing. | |
| Schemas Standard Postgres namespaces used to scope what a sync user can read and write. | Invoices Billing records synced to accounting for AR reporting. | |
| Views Curated projections over distributed data, often used as read-only sync sources. | Quotes / Estimates Job shop quotes with material and routing cost buildups; the start of the order lifecycle. | |
| Sequences Key generators that matter when external writes must not collide with application inserts. | Jobs / Work orders Released work with routings and status; the record shop-floor dashboards track. | |
| Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. | Customers Buyer records synced to CRM or accounting counterparts. | |
| Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. | Vendors Supplier records referenced on purchasing documents. |

How the Citus and E2 Shop System connectors work
Citus
- Integration surface
- PostgreSQL wire protocol; any standard Postgres driver connects to the coordinator node
- Authentication
- Database credentials (standard PostgreSQL authentication; managed deployments add cloud IAM options)
- Change detection
- PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres
- Capabilities
- read · write · CDC
E2 Shop System
- Integration surface
- No broadly documented public web API; integration typically works through the underlying database or application import/export, depending on deployment
- Authentication
- Database credentials or application-level export access on the on-premises installation
- Change detection
- Polling database tables or scheduled exports
- Capabilities
- read
- Rate limits
- Not API-bound; constrained by on-premises database access windows

FAQ
Citus and E2 Shop System integration FAQ
-
Yes. Stacksync provides a managed, real-time integration between Citus and E2 Shop System — E2 Shop System is a read-only source, so data flows from it into the other system: authenticate both systems, choose the objects to sync, map fields visually, and changes propagate in milliseconds — no code required.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Citus and E2 Shop System connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Citus–E2 Shop System integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Citus and E2 Shop System. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Citus: PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres. On E2 Shop System: Polling database tables or scheduled exports. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
-
On the Citus side: Local tables, Schemas, Views, Sequences, plus custom fields where Citus exposes them. On the E2 Shop System side: Vendors, Parts, Routings / Operations, Purchase orders. Stacksync auto-detects both schemas and converts types between the two systems.
-
E2 Shop System is a read-only source, so this integration runs one-way: Stacksync reads from E2 Shop System in real time and delivers into Citus. Field mapping and monitoring work the same as for two-way pairs.
