Comparing Azure Data Factory with Hightouch and Weld



What is Azure Data Factory
Pros
- 90+ built-in connectors (Azure SQL, Cosmos DB, SAP, Oracle, Salesforce, etc.) and support for custom REST endpoints.
- Visual pipeline orchestration with debug, parameterization, and Git integration for CI/CD.
- Hybrid data integration via Self-hosted Integration Runtime for on-premises sources.
- Integration with Azure Synapse, Databricks, and Azure Functions for flexible transformation and compute.
Cons
- Complex pricing: charges per pipeline activity, per DIU for data flows, and for data movement across regions.
- UI can be slow when working with large pipelines; error messages are often generic, requiring deeper investigation.
- Steeper learning curve for advanced features (e.g., mapping data flows with Spark under the hood).
Azure Data Factory Documentation:
What I like about Azure Data Factory
ADF’s visual pipeline authoring and integration with other Azure services (Databricks, Synapse) make it easy to build end-to-end data workflows without managing infrastructure.
What I dislike about Azure Data Factory
Pricing is multifaceted (per activity run, data movement, SSIS integration), which can be hard to forecast. Debugging pipeline errors often requires sifting through activity logs.
What is Hightouch
Pros
- Audience builder UI for non-technical users to create segments without SQL
- 70+ destinations, including CRMs, ad platforms, email & support tools
- No persistent data storage—fetches on-the-fly from your warehouse for security
- Support for real-time streaming and sub-minute latency syncs
- Granular field mapping and transformation via SQL or simple expressions
- Strong community, educational content, and responsive support
Cons
- Reverse ETL only—needs a separate ingestion tool
- Pricing based on rows/fields can become expensive at scale
- Destination API limits (e.g., Salesforce) can slow large syncs
- Custom connectors for very niche tools require waiting for team prioritization
- Non-engineers may still need data team to model data for complex use cases
Hightouch Product Description:
What I like about Hightouch
Hightouch is the easiest way to sync customer data into your tools like CRMs, email tools, and ad networks. Sync data from any source (warehouse, spreadsheets) to 70+ tools using SQL or a point-and-click UI without relying on Engineering.
What I dislike about Hightouch
What is Weld
Pros
- Premium quality connectors and reliability
- User-friendly and easy to set up
- AI assistant
- Very competitive and easy-to-understand pricing model
- Reverse ETL option
- Lineage, orchestration, and workflow features
- Advanced transformation and SQL modeling capabilities
- Ability to handle large datasets and near real-time data sync
- Combines data from a wide range of sources for a single source of truth
Cons
- Requires some technical knowledge around data warehousing and SQL
- Limited features for advanced data teams

What I like about Weld
First and foremost, Weld is incredibly user-friendly. The graphical interface is intuitive, which makes it easy to build data workflows quickly and efficiently. Even with little experience in SQL and pipeline management, we found that Weld was straightforward and easy to use. What really impressed me, however, was Weld's flexibility. It was able to handle data from a wide variety of sources, including SQL databases, Google Sheets, and even APIs. The solution also allowed us to customize my data transformations in a way that best suited my needs. Whether I needed to clean data, join tables, or aggregate data, Weld had the necessary tools to accomplish the task. Weld's performance was also exceptional. I was able to run large-scale ETL jobs quickly and efficiently, with minimal downtime via a Snowflake instance and visualization via own-hosted Metabase. The solution's scalability meant that I could process more data without any issues. Another standout feature of Weld was its support. I never felt lost or unsure about how to use a particular feature, as the support team was always quick to respond to any questions or concerns that I had. Overall, I highly recommend Weld as an ETL solution. Its user-friendliness, flexibility, performance, and support make it an excellent choice for anyone looking to streamline their data integration processes. I will definitely be using Weld for all my ETL needs going forward.
What I dislike about Weld
Weld is still limited to a certain number of integrations - although the team is super interested to hear if you need custom integrations.
Azure Data Factory vs Hightouch: Ease of Use and User Interface
Azure Data Factory
ADF’s UI provides a canvas for building pipelines and data flows. Basic data movement is intuitive, but advanced mapping data flows (visual Spark transformations) require understanding Spark concepts. Integration with Git makes collaboration easier.
Hightouch
Hightouch’s interface is modern and intuitive, with an audience builder that lets marketers define segments visually. Technical users can drop into SQL for precise control.
Azure Data Factory vs Hightouch: Pricing Transparency and Affordability
Azure Data Factory
ADF charges per pipeline activity (at least $0.25/activity), per DIU-hour for data flows, plus data movement costs (e.g., $0.25/GB). Estimating costs can be tricky due to these components, but pay-as-you-go avoids upfront fees.
Hightouch
Starts free for light use, but professional tiers scale with usage. For mid-market teams, the cost is justified by reduced engineering overhead, though very large sync volumes can be pricey.
Azure Data Factory vs Hightouch: Comprehensive Feature Set
Azure Data Factory
Features include: pipeline orchestration, mapping data flows (visual Spark jobs), hybrid integration via self-hosted runtime, triggers (schedule, event, tumbling window), monitoring & alerting, and integration with Azure Monitor. Also supports SSIS lift-and-shift for on-prem ETL workloads.
Hightouch
Reverse ETL features: audience builder, SQL-based syncs, incremental updates, dry-run mode, mapping templates, role-based access, real-time triggers, and CLI/API for GitOps. It covers most operational use cases—no ingestion layer included.
Azure Data Factory vs Hightouch: Flexibility and Customization
Azure Data Factory
ADF allows custom .NET activities, Azure Functions, and Databricks notebooks within pipelines. It supports parameterized templates, branching, and custom Azure ML scoring steps. However, customization often requires familiarity with other Azure services.
Hightouch
Hightouch balances ease-of-use with flexibility: write custom SQL queries, adjust mappings, and schedule or trigger via API. It can cover custom use cases through webhooks or generic destinations, though some advanced scenarios may need engineering support.
