> My point is even if we differentiate empty array vs null at extractor layer, the ingestion engine will still put the same default value for them Hi @Jackie-Jiang, let me first describe I want to describe the current issue, for single value column, when a field has default value 0, we can still differentiate null value vs "0" by using `IS NOT NULL`. However for the multi-value column, when a multi-value field using default value empty list, we can not differentiate the null value and the empty list by using `IS NOT NULL` do you think there are other work arounds to make this work? For this PR, I agree it won't solve the issue completely and we need to have a proper design so that ingestion layer can aware when to add null vectors. -- This is an automated message from the Apache Git Service.
