Prism is a scalable streaming loader for Amazon Redshift Spectrum. It loads S3 objects (JSONL format) into Spectrum in Parquet format continuously.
The best feature of Prism is that it transparently merges Parquet files. Thanks to this merge feature, query performance gets x3-x5 faster compared to querying unmerged Parquet files.
