get-convex/sharded-counter

This is a Convex component for implementing sharded counters that provides a key-value store from string to number with sharding to increase throughput when updating values. It's designed for developers building applications on Convex who need to track frequently-updated counters (like checkbox states or document counts) while maintaining consistency, reactivity, and caching. The component is particularly useful when you need to increment/decrement counters in parallel without causing performance bottlenecks.
