Hi @alamb @BlakeOrth , those might uncommon cases, but I wonder what the
expected behavior would be if
- Two tables happen to be created with the same path, e.g.
```
> create external table test
stored as parquet
location
's3://overturemaps-us-west-2/release/2025-12-17.0/theme=base/type=infrastructure/';
0 row(s) fetched.
Elapsed 2.955 seconds.
> create external table test2
stored as parquet
location
's3://overturemaps-us-west-2/release/2025-12-17.0/theme=base/type=infrastructure/';
0 row(s) fetched.
Elapsed 0.741 seconds.
```
By "table scoped", do we expect cache reuse in this case? If not, do we
expect the cache key to be logically some "table identifier" instead of just
table path?
- Two statements using the same path directly, e.g.
```
> select count(*) from
's3://overturemaps-us-west-2/release/2025-12-17.0/theme=base/type=infrastructure/';
+-----------+
| count(*) |
+-----------+
| 142969564 |
+-----------+
1 row(s) fetched.
Elapsed 2.305 seconds.
> select count(*) from
's3://overturemaps-us-west-2/release/2025-12-17.0/theme=base/type=infrastructure/';
+-----------+
| count(*) |
+-----------+
| 142969564 |
+-----------+
1 row(s) fetched.
Elapsed 0.037 seconds.
```
In this case, do we expect cache reuse? or how would we interpret "table
scoped" in this case?
Thanks a lot!
