Why teams connect Exasol and Gmail

Land the messages, calls, and events from Gmail in Exasol 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 Messages, Threads, Labels, Drafts from Gmail into tables in Exasol in real time, handling schema, rate limits, and retries. Because the connection works in both directions, results computed in Exasol — 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 Log sent and received Messages onto CRM contact and deal timelines automatically so reps never copy-paste email history.
  • 02 Create Drafts in a rep's mailbox from CRM templates and sequences, keeping sends authentic to the sender's address and signature.
  • 03 Consolidate data from multiple operational databases into Exasol as the central analytics layer.
  • 04 Keep dimension tables such as customers and products aligned with the systems of record.

Common sync patterns

Communications analytics without ETL

Messages, calls, and events from Gmail arrive in Exasol 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 Exasol 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 Exasol to attribute outcomes to the touches that drove them, which no single tool can do alone.

What you can sync between Exasol 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.

Exasol objects Gmail objects How this pairing syncs
Views Read-only query surfaces often used as curated sources for reverse ETL. Attachments File payloads referenced by message part; read out to storage or a document system for archival and compliance workflows. Views is specific to Exasol and Attachments to Gmail — each maps to any object or custom field on the other side.
Virtual schemas Federated views over external sources; useful for deciding what needs physical replication. History The incremental change log keyed by historyId; used for efficient delta sync so only mailbox changes since the last cursor are fetched. Virtual schemas is specific to Exasol and History to Gmail — each maps to any object or custom field on the other side.
UDF scripts In-database functions that can transform synced data after load. 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. UDF scripts is specific to Exasol and Messages to Gmail — each maps to any object or custom field on the other side.
Users and roles Grant read/write access for the dedicated integration account. Threads Conversation groupings that keep replies together; synced so a CRM timeline or support desk shows the full exchange, not isolated messages. Users and roles is specific to Exasol and Threads to Gmail — each maps to any object or custom field on the other side.
Schemas Namespaces that group the tables a sync reads from or writes into. Labels User and system labels (INBOX, SENT, custom); applied and removed via sync to mirror pipeline stages or triage states from an external system. Schemas is specific to Exasol and Labels to Gmail — each maps to any object or custom field on the other side.
Tables Primary sync target; columnar relational tables written with standard SQL. Drafts Unsent messages; created and updated from templates or sequence tools so reps review before sending from their own mailbox. Tables is specific to Exasol and Drafts to Gmail — each maps to any object or custom field on the other side.

How changes propagate between Exasol 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.

Exasol Gmail Interval-based propagation

DetectionStacksync polls Exasol for changes on an incremental schedule, reading only records changed since the previous pass. Polling with timestamp or key columns.

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

Gmail Exasol 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 Exasol as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Exasol: No API quota; concurrency is bounded by cluster resources and session limits.
  • 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.
