GlareDB 0.9 introduces significant updates, focusing on enhanced capabilities for file uploads, new data sources like SQLite and Cassandra, and improved tools for working with Excel, Lance, and MongoDB. Users can now upload CSV, JSON, and Parquet files to GlareDB Cloud for analysis, with a new function enabling queries on these uploaded files. The release adds support for SQLite and Cassandra databases, allowing users to create external tables and run queries through the GlareDB CLI and bindings. Excel integration has been enhanced to support specific sheet options, and a new feature enables saving query results as Lance tables locally. The update also includes insert support for MongoDB and Lance tables, as well as a new read_json function for handling JSON data. Additionally, GlareDB Cloud now offers a GitHub sign-in option, providing users with a managed deployment and facilitating integration with various data tools. The roadmap for future releases includes expanding support for data sources like Iceberg, Excel, and Google Sheets, as well as improving the execution engine for enhanced performance.
