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? Currently the function is
savepoint_metadata; if it covers both can we function change the name so it
applies to both savepoints and checkpoints - maybe `state_table_metadata`?
If checkpoints are not included - how does it error if we point this
function at the checkpoint file? Maybe a unit test for that would be good.
