About

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 all of this so that sites can get ready to use the new backend..
