## What it is
HikariCP is a lightweight, high-performance JDBC connection pool for Java applications. It is a production-ready, 'zero-overhead' library widely used as the default connection pool in frameworks like Spring Boot.

## Use cases
- pool jdbc database connections in a java application
- reduce database connection overhead in spring boot
- improve database performance with a fast connection pool
- manage connection lifecycle and timeouts for jdbc
- replace an aging connection pool with a faster one

## When to choose
- you need a fast, reliable, production-proven jdbc connection pool on the jvm
- you want a tiny dependency (~165Kb) with minimal configuration
- you use Spring Boot or another framework that defaults to HikariCP

## When to avoid
- you are not using JDBC or the Java/JVM ecosystem
- you need a reactive or non-blocking connection pool for R2DBC

## Facets
- artifact type: library
- maturity: stable
- function: database, database-driver, caching, benchmarking
- domain: databases, backend, developer-tools, performance
- platform: jvm, cross-platform
- tags: jdbc, connection-pool, high-performance, java
