IMPORTANT NOTE: State Table API only supports keyed state.
+### Metadata
+
+The SQL connector allows users to read metadata of savepoints in the following
way:
+```SQL
+LOAD MODULE state;
+SELECT * FROM savepoint_metadata('/root/dir/of/checkpoint-data/chk-1');
Review Comment:
> The flip talks of checkpoints and savepoint state, can we use this
funciton to access checkpoint state as well?
Yes. We can't name things in both ways. Initially we've agreed to call the
whole state processor API things as `savepoint`... and the only exception here
is the module because it's a reserved keyword in Flink SQL. If we go on this
road, then the whole state processor API including internals must be renamed
which I don't support.
