Why teams connect Apache Doris and Gmail

Land the messages, calls, and events from Gmail in Apache Doris as live tables, and write results back, without building or maintaining a pipeline.

Gmail produces a constant stream of activity — messages sent and received, calls placed and answered, meetings held, and the delivery and engagement events attached to them. That record is what the rest of the company wants to analyze, and it usually sits behind an API rather than in the warehouse. Building and babysitting an extraction pipeline is the tax most teams pay to get it out.

Stacksync syncs Attachments, History, Messages, Threads from Gmail into tables in Apache Doris in real time, handling schema, rate limits, and retries. Because the connection works in both directions, results computed in Apache Doris — segments, contact updates, suppression flags — can be written back into fields in Gmail wherever it exposes them, so analysis lands where outreach actually happens.

Common use cases

  • 01 Read Attachments and message metadata into a warehouse or document store for retention, discovery, and compliance reporting.
  • 02 Mirror Labels with pipeline or ticket states so triage done in an external tool is reflected inside the inbox.
  • 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

Communications analytics without ETL

Messages, calls, and events from Gmail arrive in Apache Doris as queryable tables, current within seconds instead of a day behind.

Engagement and delivery on live data

Sends, opens, clicks, bounces, and call outcomes from Gmail land in Apache Doris as they happen, so deliverability and response monitoring stop lagging the reality they describe.

Activity joined with everything else

Combine Gmail's activity with the CRM, product, and support data already in Apache Doris to attribute outcomes to the touches that drove them, which no single tool can do alone.

What you can sync between Apache Doris and Gmail

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 Gmail objects How this pairing syncs
Materialized Views Precomputed views readable for downstream syncs and BI. History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. Materialized Views is specific to Apache Doris and History to Gmail — each maps to any object or custom field on the other side.
Users and Roles Principals used to grant the sync connection scoped access. Messages Individual emails with headers, body, and label state; read out to a CRM or warehouse for activity logging, and sent or modified two-way from sales tools. Users and Roles is specific to Apache Doris and Messages to Gmail — each maps to any object or custom field on the other side.
Databases Logical containers that scope connections and grants. Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. Databases is specific to Apache Doris and Threads to Gmail — each maps to any object or custom field on the other side.
Tables Columnar tables in one of Doris's table models, used as sync destinations. Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Tables is specific to Apache Doris and Labels to Gmail — each maps to any object or custom field on the other side.
Unique Key Tables Tables supporting primary-key upserts, the natural target for row-level syncs. Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. Unique Key Tables is specific to Apache Doris and Drafts to Gmail — 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. Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. Aggregate Key Tables is specific to Apache Doris and Attachments to Gmail — each maps to any object or custom field on the other side.

How changes propagate between Apache Doris and Gmail

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 Gmail 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 Gmail through its API, with automatic retries and rate-limit backoff.

Gmail Apache Doris Sub-second propagation

DetectionGmail notifies Stacksync of record changes through webhook events. Incremental sync via users.history.list from a stored historyId cursor, plus real-time push notifications through Google Cloud Pub/Sub watch on the.

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.
  • Gmail: Quota is measured in units per user per second (e.g. messages.list = 5 units, messages.send = 100 units) against a 250 quota-unit/user/second limit and a daily project cap; exceeding limits returns 429 with exponential backoff expected.

Gmail

Integration surface
Gmail API (REST, v1)
Authentication
OAuth 2.0 via Google — user-authorized consent with granular scopes (gmail.readonly, gmail.modify, gmail.send, gmail.labels); restricted scopes require Google's app verification for production use
