sqlite3 using kubernetes as the backing storage
creates a namespace per file requested, which is named the base32 encoding of the filename the namespace contains a configmap called "lockfile" which contains the lock information a series of configmaps named chunk-NUMBER which contain 64kB of data each
namespaces all labelled with "kube-sqlite3-vfs": "used" to ease cleanup
TODO: all locking/unlocking
Must use only one ns as k3s gets unhappy with namespaces being created/deleted so often. Configmap names can be 253 characters long Not convinced writing is working correctly
