CrateDB + Bruin

SourceDestination

Ingest data from CrateDB 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
CrateDB tables replicate to your warehouse continuously. Analytics teams work with fresh data, not yesterday's export.
Catch issues at the source
Quality checks validate CrateDB data as it replicates. Null IDs, duplicate records, and schema drift get caught early.
Multi-source joins
Combine CrateDB 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 CrateDB with deduplication. Schema changes are detected and handled automatically.
YAML-defined, Git-versioned
Your CrateDB 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 CrateDB with SaaS APIs and other databases in one pipeline. Bruin resolves cross-source dependencies.

Before you start

CrateDB cluster access

Database credentials

Step 1

Add your CrateDB connection

Connect using CrateDB credentials with SSL support. Add this to your Bruin environment file — credentials are stored securely and referenced by name in your pipeline YAML.

Parameters

usernameUsername for CrateDB authentication
passwordPassword for CrateDB authentication
hostHostname or IP address of CrateDB cluster
portPort number for CrateDB; default: 4200 (source), 5432 (destination)
sslmodeEnable SSL connection with `sslmode=require`

connections:
  cratedb:
    type: cratedb
    uri: "cratedb://<username>:<password>@<host>:<port>?sslmode=<sslmode>"

Step 2

Create your pipeline

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

name: raw.cratedb_data
type: ingestr

parameters:
  source_connection: cratedb
  source_table: 'data'
  destination: bigquery

Step 3

Add quality checks

Add column-level and custom SQL checks to your CrateDB 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.cratedb_data

Step 4

Run it

One command. Bruin connects to CrateDB, 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
