Why teams connect Google Cloud Spanner and Slack

Mirror Slack's data into Google Cloud Spanner so your own code can read and write it like any other table, with changes flowing both ways in seconds.

Engineers integrate with tools like Slack through APIs, which means auth, pagination, rate limits, webhooks, and retry logic, all maintained forever and all different for every tool. Meanwhile the data would be trivial to use if it simply lived in Google Cloud Spanner.

Stacksync mirrors Files, Reactions, Channels, Messages from Slack into Databases, Tables, Rows, Interleaved tables in Google Cloud Spanner and keeps both sides in sync in real time. Your services query the database directly, and inserts or updates your code makes flow back into Slack, so the tool and the database never disagree.

Common use cases

  • Alert an operations channel when a data sync detects conflicts or validation failures
  • Post CRM record changes into deal or account channels so the team sees updates without opening the CRM
  • Run a two-way sync between Spanner and a SaaS tool so edits made by ops teams land back in the application database.
  • Consolidate data from a globally distributed Spanner deployment into regional business systems.

React to changes as they happen

Updates in Slack arrive as row changes in Google Cloud Spanner, so triggers, jobs, and services can respond in near real time.

One integration pattern for the whole stack

Every synced tool looks the same from the database, so each new integration is configuration, not a new codebase.

Read Slack with a query

Records from Slack are ordinary rows in Google Cloud Spanner; join them, index them, and use them in application logic without touching the vendor API.

What you can sync between Google Cloud Spanner and Slack

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.

Google Cloud Spanner objects Slack objects
Databases Top-level containers that scope schema and sync configuration. Users Workspace members with profile fields, synced against HR systems and identity providers.
Tables Relational tables mapped one-to-one to sync targets. User groups Handles like @support that map to teams in external systems.
Rows The unit of read and write in each sync cycle, keyed by primary key. Files Uploads attached to messages, retrievable for archiving.
Interleaved tables Child rows physically co-located with parents; synced as related records. Reactions Emoji responses that can drive workflows, such as approving a synced record.
Secondary indexes Used to make incremental read queries efficient on non-key columns. Channels Conversations (public, private, DMs) that messages are read from and posted to.
Change streams Capture inserts, updates, and deletes for log-style change data capture. Messages Keyed by channel and timestamp; posted via chat.postMessage and read via history methods.
