cloud.opencode.base.pool.policy.EvictionPolicy.MaxAge<T>
Type Parameters:
T - the pooled object type - 池化对象类型
Record Components:
maxLifetime - the maximum object lifetime - 最大对象生命周期
All Implemented Interfaces:
EvictionPolicy<T>
Enclosing interface:
EvictionPolicy<T>
public static record EvictionPolicy.MaxAge<T>(Duration maxLifetime) extends Record implements EvictionPolicy<T>
Maximum age eviction policy. 最大生命周期驱逐策略。

Evicts objects that have exceeded a maximum lifetime based on creation time. Essential for database connections that must be recycled periodically.

驱逐超过最大生命周期的对象（基于创建时间，而非空闲时间）。 对于必须定期回收的数据库连接至关重要。
