I've been dealing with authentication, authorization and certificates for quite some time.
Session at Gophercamp 2026
Caching filesystem access
The session will introduce common problems one has to deal with when implementing caching of filesystem access in a highly scalable system, in particularly in Kubernetes' kubelet. You will be introduced to logic primitives that are useful in a system with parallel access, all wrapped in a pluggable design for accessing cached authorization records from a host system. You will also learn the tradeoffs of staying effective while keeping your solution resource-limited. I will describe basic benchmarking techniques that are helpful when assessing performance of a system so that you have an actual proof that your caching implementation is useful, and under which conditions.
