Declarative pipeline for structured data processing to APIs

The ask

Developers frequently encounter challenges when processing structured data from files. This data often needs transformation, batching, and integration with external APIs, such as vector databases. The common approach often leads to verbose and imperative code. Current methods typically involve extensive manual handling of file input, data parsing, and sequence management. This results in code that is hard to read, debug, and maintain. General-purpose data processing libraries do not fully cater to this specific pattern of file-to-API data flow. A more declarative and composable system is needed. Developers would benefit from a solution that supports streaming data and functional transformations. This would enable building robust data pipelines with clearer logic and reduced complexity. This need is particularly urgent with the widespread adoption of AI technologies, including Retrieval-Augmented Generation. Preparing data for these applications often requires precisely this type of efficient and reliable data ingestion pipeline.
