Open source reverse-ETL platform to operationalize your data warehouse

---

Introduction

Castled is a Reverse ETL solution which enables you to make the valuable customer insights lying in your data warehouse actionable by moving them to sales, markerting and support tools of your choice. We currently support all major data warehouses incluing Snowflake, BigQuery, Redshift and Postgres as the data source and some of the most popular sales, marketing and support solutions such as Salesforce, Hubspot, Intercom, Google Ads etc as the destination.

Some of our key offerings include

• Incremental or Full data syncs from your cloud data warehouse.
• Automated failure handling and recovery.
• Reliability and Resiliance at scale.
• CFL(Castled Form Language) is a Java Annotation based UI framework, which can support the most complex UI forms from backend, thereby removing the prerequisite of having a UI developer to add a new connector.
• Kubernetes ready for easy deployment.

Performance

The throughput/latency of a data pipeline depends mostly on the destination api limitations and/or rate limits. We do make the best effort to tune it to provide the most optimal throughput possible. But to give an indication of the throughput we support, publishing a bench mark we did to transfer upto 100 million records from BigQuery to Apache Kafka.

Contribute to us

We are a huge fan of the open source community and we value your contributions. We have spent an insane amount of time customizing our framework to reduce the amount of time required to built a new connector. Here is all you need to do to add your own custom connector.

1. Implement java interfaces (ExternalAppConnector and DataSink) on the backend.

2. Customize the mapping configuration and app configuration on the UI using our java annotation based framework. Refer the mapping configuration and app configuration of our CustomerIO connector for more info.
