OptionalprefixOnly include ids that begin with this exact, case sensitive prefix.
Matched literally, never as a pattern => the prefix is bound as a parameter, so glob/SQL
metacharacters (%, _, *, ?) in it match themselves and nothing else. Omit for the whole
table. See TableProxy.startsWith for the sugar form.
Options shared by the enumeration methods on a table (TableProxy.keys / TableProxy.values / TableProxy.entries / TableProxy.count).
