got not all rows in response. cursor is needed?

[mangup]

I make simple request to my database:
rows, err := db.QueryContext(ctx, "select userid from pl_session where year = 2022 and month=01 and day = 27")
Result should be 700k rows (It is verified via db web interface).
But via go-impala I have only 160k ones.
Why?
Is it some-how related to requests with cursor?

false alarm. it were different data bases.
