    Until EOS version 5.1.8, FST metadata on FSTs were stored in a leveldb, which was often heavily contended during writes. We added a feature to move the metadata to attributes. With a minimal configuration, we should be able to switch to the new backend and FSTs automatically move from one backend to another at startup. Additionally there is some tooling to inspect all this. We briefly explain...

    This presentation gives an overview of the token support in EOS. We'll discuss the configuration options, what plugins need to be enabled for the various protocols and how to configure them. Besides this, we'll trace one particular request using tokens to see how it interacts with the existing authentication/authorization features that already exists in EOS and provide some helpful examples.
