Why teams connect Apache Druid and SendGrid
Get the data locked inside SendGrid into Apache Druid as live tables, and send results back where SendGrid can use them, without writing a pipeline.
Whatever SendGrid 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 Contacts, List, Segments, Categories from SendGrid into tables in Apache Druid continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Apache Druid can also be written back into fields in SendGrid where the tool can use them.
Common use cases
- Sync CRM contacts and their custom fields into SendGrid lists so campaign targeting reflects live sales data
- Write bounces, spam reports, and unsubscribes back to the CRM to keep email opt-in status accurate everywhere
- Query aggregated event metrics from Druid and sync them into CRM account fields for usage-based selling.
- Feed operational records into Druid via batch ingestion so analysts get interactive slice-and-dice on fresh data.
Analytics on SendGrid's data
Records and events from SendGrid land in Apache Druid as queryable tables, current within seconds and ready to join with the rest of the warehouse.
Cross-tool reporting
Combine SendGrid's data with data from every other synced system to answer questions no single tool can.
Where SendGrid accepts updates: operational write-back
Segments, scores, or reference values computed in Apache Druid sync back onto records in SendGrid, putting analysis where the work happens.
What you can sync between Apache Druid and SendGrid
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 Druid objects | SendGrid objects | |
|---|---|---|
| Dimensions String and categorical columns used for filtering and grouping in synced queries. | Contacts Marketing recipients upserted from CRM or database records, including custom field values. | |
| Metrics Numeric columns, often pre-aggregated at ingestion via rollup. | List Synced with incremental and full sync per the Stacksync docs. | |
| Ingestion Supervisors Long-running specs that pull from streams like Kafka; the write path into Druid. | Segments Query-based contact groups whose membership SendGrid computes from contact fields. | |
| Lookups Key-value mappings joined at query time, refreshable from external systems. | Categories Synced with incremental and full sync per the Stacksync docs. | |
| Tasks Batch ingestion and compaction jobs monitored during data loads. | Senders Synced with incremental and full sync per the Stacksync docs. | |
| Datasources The table-like unit of storage and querying, the main target of reads and ingestion. | Single Sends One-off marketing campaigns whose stats are read back for reporting. |

How the Apache Druid and SendGrid connectors work
Apache Druid
- Integration surface
- REST API (SQL over HTTP and native JSON queries); JDBC via Avatica
- Authentication
- Deployment-dependent: basic authentication or an authenticator extension; often fronted by a proxy
- Change detection
- Not applicable for reads out (polling by time interval); data enters Druid through streaming or batch ingestion rather than row updates
- Capabilities
- read · write
- Rate limits
- No fixed API quotas; query concurrency is bounded by broker and historical node capacity
SendGrid
- Integration surface
- REST API (v3)
- Authentication
- API key (create in SendGrid Settings > API Keys with Custom Access / Full Access for the objects to sync; key begins with "SG")
- Change detection
- Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling
- Capabilities
- read · write · webhooks
- Rate limits
- Subject to the platform's API rate limits; contact upserts are batched, asynchronous jobs rather than per-row writes

FAQ
Apache Druid and SendGrid integration FAQ
-
Yes. Stacksync provides a managed, real-time two-way integration between Apache Druid and SendGrid: authenticate both systems, choose the objects to sync (such as Apache Druid's Dimensions and Metrics), map fields visually, and changes propagate both ways in milliseconds — no code required.
-
SendGrid: Email Activity access requires an add-on subscription in SendGrid; without it the Email Activity API is not available. Apache Druid: Druid stores data in immutable, time-partitioned segments; there is no row-level update path, so writes happen through ingestion and reprocessing rather than upserts. Stacksync's field mapping accounts for these differences between Apache Druid and SendGrid without custom code.
-
Stacksync is SOC 2 Type II and ISO 27001 certified with HIPAA BAA support. Data is encrypted in transit, and a zero-persistent-storage architecture means Apache Druid and SendGrid records are not retained after a sync operation.
-
Stacksync pricing is usage-based and starts at $1,000/month, including the managed Apache Druid and SendGrid connectors, real-time two-way sync, monitoring, and support. That replaces building and maintaining a custom Apache Druid–SendGrid integration in-house.
-
Yes — Stacksync ships production-grade connectors for both Apache Druid and SendGrid. The connectors handle authentication, schema detection, rate limits, and retries; you configure the sync, and Stacksync operates it.
-
Change detection on Apache Druid: Not applicable for reads out (polling by time interval); data enters Druid through streaming or batch ingestion rather than row updates. On SendGrid: Event Webhook posts delivery and engagement events (processed, delivered, open, click, bounce, spam report) to an HTTP endpoint; contact and list changes are detected by polling. Each detected change propagates to the other side in milliseconds, with field-level conflict resolution and an inspectable event log.
