About

Apache DataFusion is an extensible, high-performance query engine written in Rust that utilizes Apache Arrow as its in-memory format. Designed for developers building data-centric systems such as databases, data frames, machine learning, and streaming applications, DataFusion offers SQL and DataFrame APIs, a vectorized, multi-threaded, streaming execution engine, and support for partitioned data sources. It natively supports formats like CSV, Parquet, JSON, and Avro, and allows for seamless integration with object stores including AWS S3, Azure Blob Storage, and Google Cloud Storage. The engine features a comprehensive query planner, a state-of-the-art optimizer with capabilities like expression coercion and simplification, projection and filter pushdown, sort and distribution-aware optimizations, and automatic join reordering. DataFusion is highly customizable, enabling the addition of user-defined scalar, aggregate, and window functions, custom data sources, query languages, etc.

About

RowCove is a native desktop application for inspecting and editing large local data files on Windows and Apple Silicon Macs. It opens structured formats including CSV, TSV, JSON, JSONL/NDJSON, Parquet, Arrow IPC and Feather, and provides table and nested-value views for reviewing records. Users can filter and sort files, inspect partition and source context in supported shards, and stage supported changes before saving a separate copy. The application is designed for data engineers, AI dataset practitioners, quantitative researchers and analysts who need to examine exports or research data without first converting them to another format. RowCove also provides authorized local Model Context Protocol (MCP) tools for compatible AI clients, including schema access, test calls, wire logs and history. Processing is performed locally; available features and performance depend on file format and system hardware.
