Thanks for the response to the issue of "Paimon ROW type internal fields Sum aggregation not working"

[齐先生 <cq...@163.com>]

Hello, Thanks a lot for the reply from the community. I’d like to follow up on two points regarding the agg function for nested fields: First, is there a plan to implement the agg functionality for nested fields in future versions? Second, if this feature isn’t going to be supported in the near term, would it be possible to add an error prompt in the DDL of future versions? Specifically, when someone tries to set configurations like 'fields.data.num.aggregate-function' = 'sum' (for nested fields), the table creation would fail with an error, to avoid invalid settings. Looking forward to your insights. Best regards, Q7

Hi,

This is a good idea. Currently has no plan to implement this.

Best,
