Closed

Description

Describe the bug

Similar to an issue mentioned in #18195, it looks like elapsed_compute from BaselineMetrics is also not tracked by scanning csv, or file scan in general.

> create external table customer
stored as csv
location '/Users/jizezhang/datafusion/benchmarks/data/tpch_sf1/csv/customer';
0 row(s) fetched. 
Elapsed 0.073 seconds.

> explain analyze
select * from customer;
... elapsed_compute=8ns ...
