Crate exarrow_rs 

exarrow-rs

ADBC-compatible driver for Exasol with Apache Arrow data format support.

This library provides high-performance database connectivity for Exasol using the ADBC (Arrow Database Connectivity) interface. It enables efficient data transfer using the Apache Arrow columnar format, making it ideal for analytical workloads and data science applications.

Features

• ADBC Interface: Standard Arrow Database Connectivity driver
• Query Execution: Execute SQL queries and retrieve results as Arrow RecordBatches
• Bulk Import: Import data from CSV, Parquet, and Arrow RecordBatches
• Bulk Export: Export data to CSV, Parquet, and Arrow RecordBatches
• Streaming: Memory-efficient streaming for large datasets
• Compression: Support for gzip, bzip2, snappy, lz4, and zstd compression
