Storing additional metadata

[anxiousmodernman]

The core function is to dump data, but we might persist additional metadata on a special key path:

/{schema}/{table}/metadata/{something}

Rather than forcing the person querying out k-v store to map a complicated data structure that contains all metadata, we might provide arrays of strings for some things

/{schema}/{table}/metadata/columns - ["id", "name", "age"]
/{schema}/{table}/metadata/types - ["numeric", "string", "numeric"]
//{schema}/{table}/metadata/primary-key - "id"
