Question

在我的aerospike数据库中添加了大量数据后，很多数据都消失了。我也试图禁用TTL和驱逐。但没有任何效果。目前我正在使用默认配置。

namespace test {
    replication-factor 2
    memory-size 4G
    default-ttl 30d # 30 days, use 0 to never expire/evict.
    storage-engine memory
}

保存了256.408个对象（24％的内存使用量），几分钟后只有133.294个对象（13％的内存使用率）。 13,229个对象已过期（似乎是正确的）被驱逐的0件物品

我的数据发生了什么？

Answer 1

1 - 你是如何插入物体的？您是否在插入对象时修改默认TTL？使用30d默认ttl，您不应该使对象到期，（假设您在256K对象之间快速运行info命令，降至133K）。对象的大小是多少？

2 - 您可以$grep thr_nsup /var/log/aerospike/aerospike.log并发布输出吗？

3 - 你可以发布$asinfo -v "namespace/test"

的输出

Answer 2

谢谢你的帮助。我在代码中发现了这个问题。 Aerospike工作正常。对不起，＆＃34;错误＆＃34;警报：D

Aerospike数据消失了
