## What it is
EloqKV is a high-performance distributed key-value database with a Redis/ValKey-compatible API, built in C++ on a transactional data substrate. It adds ACID transactions, horizontal scalability, replicated durability, and automatic tiering of cold data to S3 while keeping Redis client compatibility.

## Use cases
- drop-in Redis replacement with ACID transactions
- distributed key-value store with strong consistency
- cache that persists data durably
- scale Redis workloads beyond single-node memory limits
- tiered storage to cut memory costs for cold data
- multi-threaded high-throughput Redis API server

## When to choose
- you need Redis API compatibility plus real transactions with rollback
- your dataset exceeds memory and you want automatic disk/S3 tiering
- you need distributed ACID transactions across keys or nodes
- you want higher QPS than single-threaded Redis on multicore hardware

## When to avoid
- you need the exact Redis ecosystem of modules and tooling
- you want a battle-tested, widely deployed store like Redis or Valkey
- your workload is tiny and a plain Redis instance suffices
- you require a permissive open-source license (GPL/NOASSERTION here)
