Abstract
The subject technology initializes a statement for execution. The subject technology determines that the statement has been executing for longer than a minimum statement timeout. The subject technology periodically updates a read timestamp table with a new update timestamp for an entry corresponding to the statement. The subject technology determines whether the entry corresponding to the statement has been removed from the read timestamp table. The subject technology, in response to determining that the entry has not been removed from the read timestamp table, removes the entry from the read timestamp table. The subject technology provides a set of results from completing execution of the statement.
