Pros
- It is an open-source, composable standard for building ETL (Extract, Transform, Load) pipelines, based on the Unix philosophy of simple, single-purpose applications .
- Taps and targets communicate via standard output and JSON, making them easy to implement and language-agnostic .
- It supports "incremental extraction," as it can maintain state between runs, making data transfer efficient .
Cons
- Singer is a standard and a collection of tools, not a single, packaged application. Implementing a full pipeline requires technical expertise.
- The project's core focus is on data extraction; it doesn't handle complex data transformations natively, requiring you to use separate tools.
- As a community-driven open-source project, the support, maintenance, and quality of taps and targets can be variable.
