----------------------
Description: Users want to implement checkpoints similar to those in Hudi
DeltaStreamer. DeltaStreamer is implemented by saving values to extrametadata
in a commit file, with the key deltastreamer.checkpoint.key. We can achieve
this in Spark Client by configuring the parameter `house. datasource. write.
commonmeta. key. prefix`, but in Spark SQL, it is restricted that the prefix of
the configuration parameter must be `hoodie.` (was: Users want to implement
