Fixes [CASSJAVA-71](https://issues.apache.org/jira/browse/CASSJAVA-71). Currently, when client executes below code: ``` ResultSet rs = session.execute(SimpleStatement.newInstance("select * from kv").setPageSize(2).setTracing(true)); Iterator<Row> iter = rs.iterator(); while (iter.hasNext()) { iter.next(); } ``` The following trace events are generated: ``` cqlsh> select session_id, command, coordinator, duration, parameters, started_at from system_traces.sessions; session_id | command | coordinator | duration | parameters | started_at --------------------------------------+---------+-------------+----------+-------------------------------------------------------------------------------------------------------------------------+--------------------------------- f69b1c00-e7d7-11ef-911d-0b57c0dc9621 | QUERY | 127.0.0.1 | 1255 | {'consistency_level': 'LOCAL_ONE', 'page_size': '2', 'query': 'select * from kv', 'serial_consistency_level': 'SERIAL'} | 2025-02-10 17:53:41.312000+0000 f69c2d70-e7d7-11ef-911d-0b57c0dc9621 | QUERY | 127.0.0.1 | 918 | {'consistency_level': 'LOCAL_ONE', 'page_size': '2', 'query': 'select * from kv', 'serial_consistency_level': 'SERIAL'} | 2025-02-10 17:53:41.319000+0000 f69c5480-e7d7-11ef-911d-0b57c0dc9621 | QUERY | 127.0.0.1 | 638 | {'consistency_level': 'LOCAL_ONE', 'page_size': '2', 'query': 'select * from kv', 'serial_consistency_level': 'SERIAL'} | 2025-02-10 17:53:41.320000+0000 f69bdf50-e7d7-11ef-911d-0b57c0dc9621 | QUERY | 127.0.0.1 | 1119 | {'consistency_level': 'LOCAL_ONE', 'page_size': '2', 'query': 'select * from kv', 'serial_consistency_level': 'SERIAL'} | 2025-02-10 17:53:41.317000+0000 ``` After disabling `report-every-page-fetch`, only first page generates trace event: ``` cqlsh> select session_id, command, coordinator, duration, parameters, started_at from system_traces.sessions; session_id | command | coordinator | duration | parameters | started_at --------------------------------------+---------+-------------+----------+-------------------------------------------------------------------------------------------------------------------------+--------------------------------- e8f6ad80-e7d7-11ef-911d-0b57c0dc9621 | QUERY | 127.0.0.1 | 1628 | {'consistency_level': 'LOCAL_ONE', 'page_size': '2', 'query': 'select * from kv', 'serial_consistency_level': 'SERIAL'} | 2025-02-10 17:53:18.424000+0000 ``` -- This is an automated message from the Apache Git Service.
