## What it is
ShardingCore is a high-performance, lightweight .NET library that adds table sharding, database sharding, and read-write separation to Entity Framework Core. It works by extending DbContext so existing business code requires no changes, with zero dependencies beyond EF Core itself.

## Use cases
- shard large tables in ef core
- split database across multiple servers with ef core
- add read-write separation to entity framework core
- scale out postgres or mysql tables by date with efcore
- add sharding to existing .net app without changing business code
- multi-tenant database routing in ef core

## When to choose
- you use EF Core and need table or database sharding with minimal code changes
- you want read-write separation across replicas in a .NET application
- you need multi-tenant routing or date-based table partitioning on .NET

## When to avoid
- your project does not use Entity Framework Core
- you need sharding for non-.NET stacks or ORMs other than EF Core
- you need a fully managed distributed database rather than an application-level sharding layer
