MySQL + Bruin

SourceDestination

Ingest data from MySQL or push enriched data back — with quality checks, lineage, and scheduling. Defined in YAML, version-controlled in Git.

For business teams

What you get

Real-time warehouse sync
MySQL tables replicate to your warehouse continuously. Analytics teams work with fresh data, not yesterday's export.
Catch issues at the source
Quality checks validate MySQL data as it replicates. Null IDs, duplicate records, and schema drift get caught early.
Multi-source joins
Combine MySQL with SaaS data, APIs, and other databases in your warehouse. One Bruin pipeline handles it all.
No untracked scripts
Replication is defined in YAML, reviewed in PRs, and deployed with CI/CD. No more mystery cron jobs.

For data & engineering teams

How it works

CDC with merge strategy
Bruin handles change data capture from MySQL with deduplication. Schema changes are detected and handled automatically.
YAML-defined, Git-versioned
Your MySQL replication is a YAML file. Review in PRs, deploy with CI/CD. No more untracked database scripts.
Row-level quality checks
Validate primary keys, foreign keys, and referential integrity on every sync. Catch corruption at the source.
Multi-source pipelines
Combine MySQL with SaaS APIs and other databases in one pipeline. Bruin resolves cross-source dependencies.

Before you start

MySQL server running and accessible

User with appropriate GRANT permissions

Database exists or permission to create

Network access to MySQL port

Step 1

Add your MySQL connection

MySQL connection using standard format. Add this to your Bruin environment file — credentials are stored securely and referenced by name in your pipeline YAML.

Parameters

usernameMySQL user
passwordUser password
hostServer hostname or IP
portServer port (default 3306)
databaseDatabase name
charsetOptional character set

connections:
  mysql:
    type: mysql
    uri: "mysql://username:password@host:port/database"

Step 2

Create your pipeline

Define a YAML asset that tells Bruin what to pull from MySQL and where to land it. This file lives in your Git repo — reviewable, version-controlled, and deployable with CI/CD.

Available tables

usersordersproductslogssessions

name: raw.mysql_users
type: ingestr

parameters:
  source_connection: mysql
  source_table: 'users'
  destination: bigquery

Step 3

Add quality checks

Add column-level and custom SQL checks to your MySQL data. If a check fails, the pipeline stops — bad data never reaches downstream models or dashboards.

Validate row counts are within expected range

Ensure primary keys are unique and not null

Catch schema drift with freshness checks

columns:
  - name: id
    checks:
      - name: not_null
      - name: unique
  - name: created_at
    checks:
      - name: not_null

custom_checks:
  - name: row count within expected range
    query: |
      SELECT COUNT(*) BETWEEN 1 AND 10000000
      FROM raw.mysql_users

Step 4

Run it

One command. Bruin connects to MySQL, pulls data incrementally, runs your quality checks, and lands clean data in your warehouse. If a check fails, the pipeline stops — bad data never reaches downstream.

Backfill historical data with --start-date

Schedule with cron or trigger from CI/CD

Full lineage from MySQL to your dashboards
