Why teams connect Klaviyo and YugabyteDB

Mirror Klaviyo's data into YugabyteDB 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 YugabyteDB.

Stacksync mirrors Events, Metrics, Campaigns, Flows from Klaviyo into Tables, Indexes, Materialized Views, Schemas in YugabyteDB 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

  • Push offline, ERP, or subscription order events into Klaviyo as metrics to trigger post-purchase and win-back flows
  • Mirror campaign and flow engagement events into a warehouse for revenue attribution alongside order data
  • Run log-based CDC from YugabyteDB tables into a warehouse for analytics without batch dumps.
  • Two-way sync between YugabyteDB application tables and a CRM so product data and account records stay consistent.

React to changes as they happen

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

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Klaviyo with a query

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

What you can sync between Klaviyo and YugabyteDB

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.

Klaviyo objects YugabyteDB objects
Lists Static audience memberships sync in from CRMs and forms for targeting. Schemas Postgres-style namespaces in YSQL used to organize synced data.
Segments Dynamic audiences are readable so other tools can mirror who qualifies. Sequences ID generation objects relevant when syncing writes into YSQL tables.
Events Timestamped behavioral records tied to metrics; external order and product events are pushed in to trigger flows. CDC Streams Change streams over the storage-layer WAL consumed through logical replication or Debezium-compatible connectors.
Metrics Event type definitions organize the activity stream used in segmentation and attribution. Databases and Keyspaces Top-level containers for the YSQL (Postgres-style) and YCQL (Cassandra-style) APIs respectively.
Campaigns Email and SMS sends expose performance data for warehouse-based reporting. Tables Distributed SQL tables split into tablets; the primary read and write targets.
Flows Automation definitions and their engagement data sync outward for attribution. Indexes Global secondary indexes maintained transactionally alongside table writes.
