Why teams connect Apache Cassandra and DEAR Inventory

Give your engineers DEAR Inventory's data in Apache Cassandra: read it with normal queries, write back through the sync, and skip the ERP API entirely.

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 Stock levels, Sale orders, Purchase orders, Customers from DEAR Inventory into Apache Cassandra and keeps both sides consistent in real time. Whatever DEAR Inventory 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 DEAR Inventory with its validations respected.

Common use cases

  • Feed Cassandra change streams into search indexes or caches that must track the source of truth.
  • Consolidate data from multiple keyspaces or clusters into one reporting store.
  • Land orders, costs, and inventory movements in a warehouse for margin and stock-turn reporting.
  • Keep supplier and purchase order data aligned with the accounting system for accrual accuracy.

Where DEAR Inventory is the HR system of record: people data for internal systems

Worker and org records stay current in Apache Cassandra for provisioning, access, and reporting systems that read from the database.

Controlled write-back

Choose exactly which tables and fields may flow from Apache Cassandra back into DEAR Inventory, keeping the ERP authoritative.

Read ERP records with a query

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

What you can sync between Apache Cassandra and DEAR Inventory

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 DEAR Inventory objects
Materialized Views Server-maintained denormalized views; considered experimental and disabled by default in recent releases. Customers Buyer records aligned with CRM and accounting counterparts.
Secondary Indexes Optional indexes that allow filtered reads outside the partition key. Suppliers Vendor records referenced on purchase orders.
User-Defined Types Composite column types that syncs must flatten or map to structured fields. Stock adjustments and transfers Inventory movement transactions that explain changes in availability.
Collections List, set, and map columns handled with type-aware field mapping. Assemblies / Production Bill-of-material and production records for light manufacturing workflows.
Counters Increment-only counter columns, usually read-only in syncs. Locations Warehouses and bins that scope stock levels and fulfillment.
Keyspaces Top-level namespaces with replication settings that scope a sync connection. Products SKU records with pricing, suppliers, and bill-of-material links; the master data most syncs start from.
