Details

Trino returns results page by page; each payload carries a nextUri to follow until the query reaches a terminal state. Because that progress is mutated as rows are fetched, and S4 slots are copy-on-modify, the mutable part of the result lives in the state environment rather than in slots. This makes res behave like a cursor, as DBI expects.

Slots

connection

The TrinoConnection the statement was sent on.

statement

The SQL statement, as a string.

state

Environment holding the mutable cursor state: next_uri, columns, data, completed, rows_fetched, query_id, and the update_type and update_count of a statement that changes something.
