> When using trace_next_query() then execute_prepared_cql3_query(), it looks like tracing info are invalid (number of sessions/events and columns values are wrong).
> How to reproduce:
> {code}
> create keyspace Tests with replication = {'class': 'SimpleStrategy', 'replication_factor' : 1}
> create table Tests.stresstest (strid varchar,intid int, primary key (strid))
> {code}
> and then executing the following prepared query 50,000 times:
> {code}
> insert into Tests.stresstest (intid, strid) values (?, ?)
> {code}
> produces the following results:
> {code}
> localhost> select count(*) from Tests.stresstest
> +------------+
> | count |
> +============+
> | 50000 |
> +------------+
> localhost> select count(*) from system_traces.events
> +------------+
> | count |
> +============+
> | 20832 |
> +------------+
> localhost> select count(*) from system_traces.sessions
> +------------+
> | count |
> +============+
> | 26717 |
> +------------+
> localhost> select * from system_traces.sessions limit 10
