   I think what you're looking for is defining 'namespaces' or 'databases' 
rather than prefixes, which could then be : 
   
   ```rust
   for table in ["table1", "table2"] {
     ctx.register(uri: format!("s3://bucket/active/{table}"))
   }
   // trailing space = list
   ctx.register(uri: "s3://bucket/active/", namespace: "active")
   // supports globs
   ctx.register(urI: "s3://bucket/active/{*}")
   ```
   
   ```rust
   ctx.sql("select * from active.table1");
   ```
   
   This is kinda the way spark works
