【问题描述】：
在我的 aerospike 数据库中添加了大量数据后，很多数据消失了。 我还尝试禁用 TTL 和驱逐。但没有任何效果。 目前我使用的是默认配置。
namespace test {
replication-factor 2
memory-size 4G
default-ttl 30d # 30 days, use 0 to never expire/evict.
storage-engine memory
}
几分钟后保存了 256.408 个对象（内存使用率为 24%） 只有 133.294 个对象（13% 的内存使用）。 13,229 个对象过期（似乎是正确的） 0 个对象被驱逐
我的数据怎么了？

【问题讨论】：
-
您能否提供命名空间的完整统计信息。命令：asinfo -v "命名空间/测试"
-
@DerCoder 也在：discuss.aerospike.com/t/aerospike-data-expire/3329/6 上发布了这个，说已解决，问题出在他的代码上，Aerospike 工作正常。

@DerCoder，介意分享一下最终的问题吗？ m.xkcd.com/979
