love1693294577 commented on issue #6723: Druid-redis does not provide a historical buffer interface? URL: https://github.com/apache/incubator-druid/issues/6723#issuecomment-446094093 > 请检查[redis缓存文档](https://github.com/apache/incubator-druid/blob/master/docs/content/development/extensions-contrib/redis-cache.md)以了解如何使用它。以下是一个例子： > > ``` > # Use cache > druid.historical.cache.useCache=true > druid.historical.cache.populateCache=true > druid.historical.cache.unCacheable=["select", "scan"] > > druid.cache.type=redis > druid.cache.host=127.0.0.1 > druid.cache.port=8080 > ``` 是的 我只想打开历史悠久的缓冲区 我在所有common.runtime.properties中配置它 Druid.cache.host = xx.xxx.xxx.13 Druid.cache.port = 6379 并在所有历史节点中配置 druid.historical.cache.useCache = true druid.historical.cache.populateCache = true Druid.historical.cache.unCacheable = [] Druid.cache.type = redis 但redis中仍然没有缓冲数据 我尝试配置代理的缓冲区，但历史记录中没有配置，这已经用redis缓冲数据，并且该段有缓冲区信息。
