Caching

hitting a weird issue where my local cache gets stale right before the write finishes. using this pattern: if the db updates midway, the cache stays stale for the full minute. how do you guys handle invalidation without blowing up performance?

hey everyone, seeing some weird latency spikes on our main read path. currently using a simple . when the key expires, everything hits the db at once and the app chokes for a second. is this just a classic cache stampede or am i missing a config setting?

hey everyone, seeing something weird. we are using a shared redis instance for user sessions and occasionally user a sees user b's dashboard after a deploy. we're just doing basic get/set. could this be a key collision or am i missing something about how eviction handles key name…

been seeing some weird latency spikes on our read through cache whenever a key expires. i expected a simple miss, but it looks like we get a burst of requests hitting the origin simultaneously. is there a standard pattern to handle this without building a full distributed lock?

currently deciding between local in memory caching and a dedicated redis cluster for a high traffic api. redis adds 2ms latency per call, but local cache is killing our heap memory. has anyone actually hit a wall using a sidecar redis for this or is the overhead worth the consist…

everyone treats redis like a magic spell for scaling. it's not. you are just adding a brittle layer of complexity and cache invalidation headaches for a 20ms gain. if your db is struggling, optimize the query or read replica instead of wrapping everything in this: most of your ca…
