## What it is
LocustDB is an experimental, embeddable analytics database written in Rust, designed for extremely fast query performance and storage efficiency on commodity hardware. It ships as a CLI binary with a REPL and can load CSV/CSV.gz files, persist data to disk, and run massively parallel analytical queries.

## Use cases
- analyze billions of records per second on a single desktop pc
- run fast analytical queries over large csv files
- embed a high-performance columnar analytics engine in a rust application
- query hundreds of millions of records directly from disk
- explore large datasets interactively from the command line

## When to choose
- you need blazing-fast OLAP-style analytics on a single machine
- you want an embeddable analytics database in Rust
- you're loading and querying large CSV datasets repeatedly

## When to avoid
- you need a production-hardened database with broad SQL support
- you require multi-node distributed deployments
- you need transactional or OLTP workloads

## Facets
- artifact type: library
- maturity: experimental
- function: database, analytics, cli
- domain: databases, analytics, big-data, developer-tools
- platform: rust, cli
- tags: columnar, olap, embeddable, query-engine, high-performance, linux
