Caches are configured as a named resource: 7 8 ```yaml 9 cache_resources: 10 - label: foobar 11 memcached: 12 addresses: 13 - localhost:11211 14 ttl: 60 15 ``` 16 17 > It's possible to layer caches with read-through and write-through behaviour using the [`multilevel` cache][cache.multilevel]. 18 19 And then any components that use caches have a field `resource` that specifies the cache resource: 20 21 ```yaml 22 pipeline: 23 processors: 24 - cache: 25 resource: foobar 26 operator: add 27 key: '${! json("message.id") }' 28 value: "storeme" 29 - bloblang: root = if errored() { deleted() } 30 ``` 31 32 For the simple case where you wish to store messages in a cache as an output destination for your pipeline check out the [`cache` output][output.cache]. To see examples of more advanced uses of caches such as hydration and deduplication check out the [`cache` processor][processor.cache]. 33 34 You can find out more about resources [in this document.][config.resources] 35 36 import ComponentSelect from '@theme/ComponentSelect'; 37 38 <ComponentSelect type="caches"></ComponentSelect> 39 40 [cache.multilevel]: /docs/components/caches/multilevel 41 [processor.cache]: /docs/components/processors/cache 42 [output.cache]: /docs/components/outputs/cache 43 [config.resources]: /docs/configuration/resources
