Dynamodb query error - Query key condition not supported

Question

I am trying to query my dynamodb table to get feed_guid and status_id = 1. But it returns Query key condition not supported error. Please find my table schema and query.

Answer 1

As mentioned, the attribute included in "KeyConditionExpression" should be your hash key only, matching your base table schema (in this case 'feed_guid'). If you want to query on both 'feed_guid' and 'status_id', you need to create the table with hash and range key and specify 'status_id' as your range key.

Global secondary indexes are completely separate from the base table, so in this case you can query the indexes separately (use 'status_id' in key condition when querying StatusIndex and use 'user_id' in key condition when querying UserIdIndex).
