Why teams connect Pendo and VoltDB

Give Pendo the users, events, and records that live in VoltDB in real time, and sync the cohorts and scores Pendo computes back into VoltDB where your applications read them.

A database holds the rows your business runs on: the users, events, orders, and records that every service reads and writes. Pendo is where people make sense of them, as dashboards, funnels, cohorts, and metrics. Moving the data from VoltDB into Pendo usually means a hand-built extract or a change-data-capture pipeline that breaks the moment a column is renamed, and reporting that always trails last night's load.

Stacksync syncs Partitioned Tables, Replicated Tables, Stored Procedures, Materialized Views in VoltDB with Features / Pages / Guides (metadata), Visitors, Accounts, Feature Events in Pendo in real time and in both directions. Operational rows flow into Pendo as they change, so dashboards read current data with no pipeline to maintain, and the segments, cohorts, or scores Pendo computes flow back into VoltDB, where the applications and services that read from it get them at normal query latency. Field-level mapping, schema and type translation, and conflict resolution are handled for you.

Common use cases

  • 01 Pull NPS scores and poll responses into a database so voice-of-customer sits next to revenue, renewal, and churn signals for analysis.
  • 02 Push warehouse-computed Account attributes (plan, ARR, renewal date, health score, CSM owner) onto Pendo Accounts via the Metadata API so segments and guide targeting stay current.
  • 03 Sync customer or account reference data from a CRM into VoltDB replicated tables for in-transaction lookups such as fraud or policy checks.
  • 04 Stream committed VoltDB results out through export targets into a warehouse for historical analysis.

Common sync patterns

Where Pendo builds cohorts or scores: results your services can read

Segments, cohorts, or scores computed in Pendo sync back into VoltDB, where the services that read from the database act on them at query speed without calling the analytics API.

Analytics on live operational data, minus the pipeline

The users, events, orders, and records stored in VoltDB land in Pendo as they change, so dashboards, funnels, and metrics run on current data instead of last night's extract.

One version of each user or account

A user, account, or record corrected in either system updates the other, so the identity your reports group by matches the identity your database stores.

What you can sync between Pendo and VoltDB

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.

Pendo objects VoltDB objects How this pairing syncs
Feature Events Click/interaction events on tagged features, read-only through the Aggregation API over an event-time window and joined to the Feature definitions. Partitioned Tables Tables sharded across partitions by a partitioning column; the primary transactional store and sync target. Feature Events is specific to Pendo and Partitioned Tables to VoltDB — each maps to any object or custom field on the other side.
Page Events Page-view events for tagged pages; read-only via the Aggregation API, used for adoption and path analysis in a warehouse. Replicated Tables Small reference tables copied to every partition, a common landing spot for synced lookup data. Page Events is specific to Pendo and Replicated Tables to VoltDB — each maps to any object or custom field on the other side.
Guide Events Guide seen/advanced/dismissed and step events for in-app walkthroughs; read-only through the Aggregation API to measure onboarding flow adoption. Stored Procedures Precompiled transactional units that serve as the primary write interface. Guide Events is specific to Pendo and Stored Procedures to VoltDB — each maps to any object or custom field on the other side.
Poll / NPS Responses Survey answers and NPS scores captured in-app (pollEvents / npsEvents); read-only via the Aggregation API as voice-of-customer data. Materialized Views Synchronously maintained aggregates over tables, useful as pre-computed read sources. Poll / NPS Responses is specific to Pendo and Materialized Views to VoltDB — each maps to any object or custom field on the other side.
Features / Pages / Guides (metadata) Definitions of tagged UI elements listed through the entity endpoints; read-only reference used to label and join the event streams. Streams Insert-only constructs that feed the export subsystem with committed rows. Features / Pages / Guides (metadata) is specific to Pendo and Streams to VoltDB — each maps to any object or custom field on the other side.
Visitors End-user records with agent-collected and custom fields; queried through the Aggregation API and enriched with custom fields written back via the Metadata API. Export Targets and Topics Connectors that push committed data to external systems such as Kafka or JDBC sinks. Visitors is specific to Pendo and Export Targets and Topics to VoltDB — each maps to any object or custom field on the other side.

How changes propagate between Pendo and VoltDB

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.

Pendo VoltDB Interval-based propagation

DetectionStacksync polls Pendo for changes on an incremental schedule, reading only records changed since the previous pass. Polling - reads query the Aggregation API over event-time windows.

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

VoltDB Pendo Interval-based propagation

DetectionStacksync polls VoltDB for changes on an incremental schedule, reading only records changed since the previous pass. Export streams and topics push committed changes to configured targets.

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

Rate-limit considerations

  • Pendo: Pendo does not publish fixed numeric limits; it throttles heavy Aggregation queries with 429s and caps/paginates large responses, so wide exports are paced and time-windowed.
  • VoltDB: No API rate limits; throughput is bounded by partition count and cluster sizing.

How the Pendo and VoltDB connectors work

Pendo

Integration surface
Pendo Engage API (REST) on app.pendo.io (US) / app.eu.pendo.io (EU), base path /api/v1/ - Aggregation API for reads and the Metadata API for writes
Authentication
Integration key sent in the x-pendo-integration-key header, generated in Subscription Settings; keys are scoped read-only or read/write, so writes require a read/write key
Change detection
Polling - reads query the Aggregation API over event-time windows; no change-data-capture feed and no data-change webhooks. Writes go through the Metadata API on demand.
Capabilities
read · write
Rate limits
Pendo does not publish fixed numeric limits; it throttles heavy Aggregation queries with 429s and caps/paginates large responses, so wide exports are paced and time-windowed.

VoltDB

Integration surface
SQL over JDBC plus native client libraries and an HTTP/JSON interface
Authentication
Database credentials
Change detection
Export streams and topics push committed changes to configured targets; otherwise polling
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by partition count and cluster sizing.
