## What it is
Alenka is a GPU-based column-store database engine written in CUDA that leverages vectorized processing and GPU memory bandwidth for fast analytical queries. It uses a Pig-Latin-like query language, GPU CSV loading, and offers a JDBC driver for integration.

## Use cases
- run analytical SQL-like queries entirely on the GPU
- load large CSV files into a database at high speed
- execute filter, join, group, and order operations on columnar data
- query compressed data directly on the GPU
- connect a Java application to a GPU database via JDBC
- accelerate TPC-H style benchmark workloads

## When to choose
- you have an NVIDIA GPU and want to accelerate analytical query workloads
- you need fast bulk CSV ingestion with GPU parsing
- you want columnar storage with data skipping and GPU-side compression
- you're experimenting with GPU database research or benchmarks

## When to avoid
- you need a production database with active maintenance and support
- you don't have an NVIDIA GPU or CUDA toolchain
- you need transactional (OLTP) workloads or full SQL compliance
- you require cross-platform support beyond Linux/CUDA environments
