I'm testing out using delta table with DynamoDB logStore. From what I can tell, if I delete the table in S3, the dynamoDB entry remains dangling, and will stop me from recreating the table later (because the dynamodb logstore errors when dynamodb knows about a table but S3 does not have a file for it, with "Old entries for table %s still exist in the external store" message). The only solution I see for this is to manually go into dynamodb and delete the entry if I wipe the table from S3.
