Why teams connect Apache Doris and Lemlist

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

Whatever Lemlist 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 Activities, Unsubscribes, Webhooks, Team Members from Lemlist into tables in Apache Doris continuously, handling schema, rate limits, and retries. Because the sync is bi-directional, results computed in Apache Doris can also be written back into fields in Lemlist where the tool can use them.

Common use cases

  • 01 Push enriched leads from a warehouse or list-building workflow into Lemlist campaigns automatically
  • 02 Propagate unsubscribes and bounces back to the CRM and other outreach tools for suppression compliance
  • 03 Consolidate event and transactional data from multiple sources into one real-time OLAP layer.
  • 04 Land CRM and operational database records in Doris for low-latency dashboards over fresh data.

Common sync patterns

Cross-tool reporting

Combine Lemlist's data with data from every other synced system to answer questions no single tool can.

Where Lemlist accepts updates: operational write-back

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

History that outlives the tool

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

What you can sync between Apache Doris and Lemlist

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 Doris objects Lemlist objects How this pairing syncs
Unique Key Tables Tables supporting primary-key upserts, the natural target for row-level syncs. Leads Per-campaign prospect records sync in from enrichment sources and back out with status. Unique Key Tables is specific to Apache Doris and Leads to Lemlist — each maps to any object or custom field on the other side.
Aggregate Key Tables Tables that pre-aggregate on load, used for metric rollups. Activities Engagement records such as opens, clicks, replies, and bounces sync to CRM timelines. Aggregate Key Tables is specific to Apache Doris and Activities to Lemlist — each maps to any object or custom field on the other side.
Partitions Range or list partitions that bound incremental loads. Unsubscribes Opt-out records propagate to other outreach tools and the CRM for compliance. Partitions is specific to Apache Doris and Unsubscribes to Lemlist — each maps to any object or custom field on the other side.
Materialized Views Precomputed views readable for downstream syncs and BI. Webhooks Hook subscriptions define which activity events are pushed to external endpoints. Materialized Views is specific to Apache Doris and Webhooks to Lemlist — each maps to any object or custom field on the other side.
Users and Roles Principals used to grant the sync connection scoped access. Team Members Sender and seat records map outreach activity to reps in other systems. Users and Roles is specific to Apache Doris and Team Members to Lemlist — each maps to any object or custom field on the other side.
Databases Logical containers that scope connections and grants. Campaigns Outreach campaigns are the container leads are pushed into from CRMs and list-building workflows. Databases is specific to Apache Doris and Campaigns to Lemlist — each maps to any object or custom field on the other side.

How changes propagate between Apache Doris and Lemlist

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.

Apache Doris Lemlist Interval-based propagation

DetectionStacksync polls Apache Doris for changes on an incremental schedule, reading only records changed since the previous pass. Polling on partition or timestamp columns for reads.

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

Lemlist Apache Doris Sub-second propagation

DetectionLemlist notifies Stacksync of record changes through webhook events. Webhooks on outreach activity events, plus polling.

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

Rate-limit considerations

  • Apache Doris: No API quotas; load throughput depends on cluster resources and load-job configuration.
  • Lemlist: Subject to the platform's API rate limits.
