908446997 MDU6SXNzdWU5MDg0NDY5OTc= 1353 ?_nocount=1 for opting out of table counts 9599 closed 0     2 2021-06-01T15:53:27Z 2021-06-01T16:18:54Z 2021-06-01T16:17:04Z OWNER  

Running a trace against a CSV streaming export with the new _trace=1 feature from #1351 shows that the following code is executing a select count(*) from table for every page of results returned: https://github.com/simonw/datasette/blob/d1d06ace49606da790a765689b4fbffa4c6deecb/datasette/views/table.py#L700-L705

This is inefficient - a new ?_nocount=1 option would let us disable this count in the same way as #1349: https://github.com/simonw/datasette/blob/d1d06ace49606da790a765689b4fbffa4c6deecb/datasette/views/base.py#L264-L276
