I’m trying to obtain a count of items in a Dynamodb table - I can run this query fine
scan user_Id from myUploads
but if I run
scan user_Id from myUploads GROUP BY user_Id
I get an error:
Error running query: Error parsing query at line 1
Is this related to Redash, DQL or Dynamo? Where is the best place to learn about DQL examples?
ultimately I’d like a table that counts entries for unique values of user_Id e.g.
