Question

我有一个Influxdb数据库，由于激活了保留策略，该数据库正在丢失数据。

我将influxdb代码从v1.6.3升级到了v1.7.7，但是行为是相同的。

> SHOW RETENTION POLICIES ON "telegraf"
name    duration shardGroupDuration replicaN default
----    -------- ------------------ -------- -------
autogen 0s       168h0m0s           1        false
forever 0s       168h0m0s           1        true

由于持续时间设置为“ 0s”，因此我永远不会看到保留策略被激活。非常感谢您的帮助。

Answer 1

如果您不希望永久保留策略，只需在查询后写入即可。

> DROP RETENTION POLICY "forever" ON "telegraf"

并将自动生成保留策略设置为telegraf数据库的默认设置。

> ALTER RETENTION POLICY "autogen" ON "telegraf" DEFAULT

Inlfuxdb保留策略未正确激活
