Why teams connect Apache Cassandra and E2 Shop System

Give your engineers E2 Shop System's data in Apache Cassandra: 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 Apache Cassandra, so Apache Cassandra 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 Invoices, Quotes / Estimates, Jobs / Work orders, Customers from E2 Shop System into Apache Cassandra 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 Apache Cassandra sync back into E2 Shop System with its validations respected.

Common use cases

  • Replicate high-volume event or profile tables from Cassandra into a warehouse for analytics that CQL cannot express.
  • Sync customer profile data between Cassandra and a CRM so operational apps and sales tools agree.
  • Replicate job and work order status into a reporting database to power shop-floor and delivery dashboards.
  • Sync customer and invoice data to accounting or CRM so the front office is not re-keying from the ERP.

Read ERP records with a query

Records from E2 Shop System live in Apache Cassandra as ordinary tables or collections, joinable with the rest of your data.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the E2 Shop System interface, limits, and retries.

React to ERP changes

Updates in E2 Shop System arrive as row changes in Apache Cassandra, so jobs and triggers can respond as the business record changes.

What you can sync between Apache Cassandra 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.

Apache Cassandra objects E2 Shop System objects
Collections List, set, and map columns handled with type-aware field mapping. Jobs / Work orders Released work with routings and status; the record shop-floor dashboards track.
Counters Increment-only counter columns, usually read-only in syncs. Customers Buyer records synced to CRM or accounting counterparts.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Vendors Supplier records referenced on purchasing documents.
Tables Wide-column tables addressed by partition key, the unit of row-level sync. Parts Part masters with routings and material definitions specific to each shop.
Partitions and Rows Records located by partition and clustering keys during reads and upserts. Routings / Operations Per-part operation sequences that carry estimated and actual times.
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Purchase orders Outside material and service purchases tied to jobs.

How the Apache Cassandra and E2 Shop System connectors work

Apache Cassandra

Integration surface
CQL over the Cassandra native binary protocol
Authentication
Database credentials (password authenticator); TLS and role-based grants where configured
Change detection
Commit-log based CDC on tables with CDC enabled, or polling using writetime metadata and timestamp columns
Capabilities
read · write · CDC
Rate limits
No API quotas; throughput is governed by cluster capacity and consistency-level choices

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
