GlareDB, a database system designed for querying distributed data without the need for complex ETL pipelines, has been made open source as announced in June 2023. Users can access the GitHub repository to download the binary for their platform and run GlareDB locally for ad hoc queries on Parquet files or in server mode for connecting multiple Postgres-compatible clients to various data sources. The system supports both local and cloud implementations, offering a managed deployment via console.glaredb.com, with options for a free serverless tier or a paid dedicated tier. The developers aim to enhance user experience with intuitive SQL extensions and increase the number of supported data sources, inviting community contributions for new features or data sources.
