Why teams connect Jdbc and Klaviyo

Mirror Klaviyo's data into Jdbc so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Klaviyo through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Jdbc.

Stacksync mirrors Metrics, Campaigns, Flows, Templates from Klaviyo into Stored procedures & functions, Sequences, Tables, Views in Jdbc and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Klaviyo, so the tool and the database never disagree.

Common use cases

  • 01 Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • 02 Keep suppression and consent status consistent between Klaviyo and other email or SMS tools
  • 03 Connect a niche or legacy RDBMS that has no dedicated Stacksync connector but ships a JDBC driver, using its JDBC URL to sync it two-way.
  • 04 Incrementally sync a high-volume table by polling an updated_at or auto-increment column, keeping a downstream store fresh without full reloads.

Common sync patterns

Read Klaviyo with a query

Records from Klaviyo are ordinary rows in Jdbc; join them, index them, and use them in application logic without touching the vendor API.

Automate Klaviyo from your codebase

Write to the synced tables in Jdbc and Stacksync propagates the change into Klaviyo, replacing custom integration code.

React to changes as they happen

Updates in Klaviyo arrive as row changes in Jdbc, so triggers, jobs, and services can respond in near real time.

What you can sync between Jdbc and Klaviyo

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.

Jdbc objects Klaviyo objects How this pairing syncs
Primary keys & indexes Key and index definitions read via DatabaseMetaData; the primary key is required for reliable upserts, and indexes on the cursor column keep incremental polling fast. Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Primary keys & indexes is specific to Jdbc and Campaigns to Klaviyo — each maps to any object or custom field on the other side.
Schemas & catalogs Namespaces that group tables and views; the connector targets a schema/catalog and lists its objects from the JDBC metadata to build the sync. Flows Automation definitions and their engagement data sync outward for attribution. Schemas & catalogs is specific to Jdbc and Flows to Klaviyo — each maps to any object or custom field on the other side.
Stored procedures & functions Server-side routines callable via JDBC CallableStatement; invoked for custom read or write logic when a table-level mapping is not enough. Templates Message templates are accessible via API for content management workflows. Stored procedures & functions is specific to Jdbc and Templates to Klaviyo — each maps to any object or custom field on the other side.
Sequences Server-generated identity values; relevant when writing rows into tables whose keys are assigned by the database rather than the source system. Catalog Items Product catalog records synced from an ERP or PIM power product blocks and back-in-stock triggers. Sequences is specific to Jdbc and Catalog Items to Klaviyo — each maps to any object or custom field on the other side.
Tables The base relational tables in the target database; synced two-way as rows over SQL, with each table's primary key driving upserts and row-level updates. Tags Organizational labels on campaigns, flows, and lists support reporting rollups. Tables is specific to Jdbc and Tags to Klaviyo — each maps to any object or custom field on the other side.
Views Stored SELECT queries exposed like tables; read-only projections synced outbound when raw base tables should not be exposed downstream. Profiles Person records with arbitrary custom properties are the target for CRM and warehouse-sourced attributes. Views is specific to Jdbc and Profiles to Klaviyo — each maps to any object or custom field on the other side.

How changes propagate between Jdbc and Klaviyo

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.

Jdbc Klaviyo Interval-based propagation

DetectionStacksync polls Jdbc for changes on an incremental schedule, reading only records changed since the previous pass. No native change feed.

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

Klaviyo Jdbc Sub-second propagation

DetectionKlaviyo notifies Stacksync of record changes through webhook events. Polling on updated timestamps.

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

Rate-limit considerations

  • Jdbc: No SaaS-style request quota. Throughput is bounded by the target database's max connections and connection-pool size, plus the CPU and I/O it shares with production queries, so heavy syncs can contend with live workloads.
  • Klaviyo: Per-endpoint burst and steady rate limits apply.

How the Jdbc and Klaviyo connectors work

Jdbc

Integration surface
JDBC API (java.sql / javax.sql) executing SQL through a JDBC driver, typically a pure-Java Type 4 driver; reaches any relational database with a driver - PostgreSQL, MySQL, SQL Server, Oracle, IBM DB2, and others - via a JDBC URL such as jdbc:postgresql://host:5432/db.
Authentication
A database user's username and password supplied in the JDBC connection (DriverManager or a DataSource), typically over a TLS/SSL-encrypted connection. Some drivers add Kerberos, integrated Windows auth, or cloud IAM-token auth, but the available methods depend on the target database and its driver.
Change detection
No native change feed. Incremental sync polls a cursor column - an updated_at timestamp or an auto-incrementing key - to pull new and changed rows; detecting deletes needs soft-delete flags or database triggers writing to a shadow table. No webhooks.
