Why teams connect Apache Pinot and Resend

Get the data locked inside Resend into Apache Pinot as live tables, and send results back where Resend can use them, without writing a pipeline.

Whatever Resend is used for, it accumulates data the rest of the company wants to analyze, and that data usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay for it.

Stacksync syncs Domains, Email events, API keys, Emails from Resend into tables in Apache Pinot continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Apache Pinot can also be written back into fields in Resend where the tool can use them.

Common use cases

  • Write delivery, bounce, and complaint events back to the CRM or a Postgres table for deliverability reporting.
  • Trigger transactional sends when a row changes in an operational database, such as an order status update.
  • Serve user-facing analytics from Pinot while syncing daily rollups to finance and ops tools.
  • Keep upsert-enabled real-time tables aligned with mutable operational records streamed from source systems.

Where Resend accepts updates: operational write-back

Segments, scores, or reference values computed in Apache Pinot sync back onto records in Resend, putting analysis where the work happens.

History that outlives the tool

A continuously synced copy in Apache Pinot preserves a queryable record even as data ages out of Resend or gets changed inside it.

Analytics on Resend's data

Records and events from Resend land in Apache Pinot as queryable tables, current within seconds and ready to join with the rest of the warehouse.

What you can sync between Apache Pinot and Resend

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 Pinot objects Resend objects
Indexes Inverted, range, and star-tree indexes that determine which sync queries run at low latency. Audiences Named contact lists that broadcasts target; typically mirrored from CRM segments.
Tenants Logical groupings that isolate workloads on shared clusters. Broadcasts One-to-many campaign sends addressed to an audience.
Tables The queryable unit, defined as offline, real-time, or hybrid; the main read target. Domains Verified sending domains with DNS and DKIM status.
Schemas Column definitions (dimensions, metrics, time columns) mapped during integration setup. Email events Delivered, bounced, complained, opened, and clicked events emitted via webhooks and written back to source systems.
Segments Immutable data files that batch ingestion uploads and the cluster serves. API keys Scoped credentials managed per environment for send and read access.
Real-time Tables Tables fed continuously from streams like Kafka, including upsert-enabled tables. Emails Sent messages retrievable by ID with current delivery status.
