By making it a required argument, making sure the topology version is
pinned for the duration of the query. This is needed because mutation
dump queries bypass the storage proxy, where this pinning usually takes
place. So it has to be enforced here.
This file contains facilities to dump the underlying mutations contained
in various mutation sources -- like memtable, cache and sstables -- and
return them as query results. This can be used with any table on the
system. The output represents the mutation fragments which make up said
mutations, and it will be generated according to a schema, which is a
transformation of the table's schema.
This file provides a method, which can be used to implement the backend
of a select-statement: it has a similar signature to regular query
methods.
