VersionBloomRedisConfig

Info

Redis configuration for the version module's bloom filter, used to prevent cache penetration on app version lookups.

Overview

VersionBloomRedisConfig provisions a dedicated LettuceConnectionFactory and StringRedisTemplate for the version bloom filter. The bloom filter uses Redis bitmaps to quickly reject non-existent appName values before hitting the database.

Configuration

Property	Value
Database	DB 0 (configurable via REDIS_VERSION_BLOOM_DATABASE)
Connection	Standalone Redis (host/port/password from global env)

Beans

Bean	Type	Qualifier
Connection Factory	LettuceConnectionFactory	versionBloomRedisConnectionFactory
Redis Template	StringRedisTemplate	versionBloomRedisTemplate

Environment Variables

Variable	Default	Description
REDIS_HOST	127.0.0.1	Redis server host
REDIS_PORT	6379	Redis server port
REDIS_PASSWORD	(empty)	Redis authentication password
REDIS_VERSION_BLOOM_DATABASE	0	Redis database number for bloom filter

Tips

The bloom filter is rebuilt from the database on application startup to ensure consistency.
