Overview of Weld

What is Weld?

Weld is a modern ETL (Extract, Transform, Load) platform designed to empower data teams with fast and reliable data movement. It facilitates near real-time data pipelines to support analytics, AI, and operational workflows. Weld helps businesses integrate data from various sources into their data warehouse or storage, making it analysis-ready.

How does Weld work?

Weld simplifies data integration through automated schema migrations, API versioning, and endpoint maintenance. The platform’s key features include:

  • Data Extraction: Weld can extract and load data from numerous sources directly into data warehouses or storage.
  • Data Transformation: The platform allows users to transform data using their preferred tools, such as dbt, with orchestration and monitoring capabilities.
  • Data Loading: With its custom connector feature, Weld allows users to build connectors for any API, streamlining the data loading process.

Key Features

  • Zero Maintenance Data Pipelines: Automatic schema migrations, API versioning, and endpoint maintenance eliminate the need for constant developer oversight.
  • Schema Change Detection: Automatically detects schema changes, locking schemas at the source and destination to prevent data mismatches.
  • Duplicate Detection: Identifies and flags duplicate data entries, maintaining data quality.
  • Real-Time Monitoring: Pipeline dashboards provide real-time visibility into pipeline status, showing running, queued, or errored processes.
  • Self-Healing Pipelines: Automatically retries failed syncs, ensuring reliable data delivery.

Integration and Connectivity

Weld integrates with a variety of modern data technologies, including Google BigQuery, Snowflake, and Databricks. It supports numerous connectors, including popular marketing, sales, finance, and engineering applications, as well as databases and file storage systems.

  • Popular Marketing Connectors: Google Ads, Facebook Ads, TikTok Ads, Amazon Ads
  • Popular Application Connectors: Shopify, Klaviyo, Salesforce, HubSpot
  • Popular Database Connectors: PostgreSQL, MongoDB, MS SQL Server, Airtable, MySQL
  • Popular File Connectors: Excel, Google Sheets, FTP, Google Drive, OneDrive

Transform Your Data

Weld seamlessly integrates with dbt, enabling users to run and monitor dbt jobs with scheduling, logging, and alerting. Users can also orchestrate other transformation platforms alongside their pipelines, providing a unified view of data processing.

Weld Connect REST API

The platform offers a production-ready REST API for programmatic control of Weld. The API allows users to automate connections, configure ELT syncs, monitor status, and embed the flow inside their own products.

Custom Connector

Weld’s custom connector feature enables users to build a connector for any API in days, not weeks. Users only need to implement two endpoints: /schema to describe the tables and POST / to return data. Weld handles the scheduling, retries, monitoring, and loading of data into the warehouse.
