timsaucer opened a new issue, #15565: URL: https://github.com/apache/datafusion/issues/15565
### Describe the bug When you use an FFI Table Provider, we create a session context by parsing a string representation of a session config. This happens in [this line](https://github.com/apache/datafusion/blob/main/datafusion/ffi/src/table_provider.rs#L237). The problem is this is setting a deprecated option `enable_options_value_normalization` to the same value it already has. This generates a warning even though we aren't actually changing the value. [This line](https://github.com/apache/datafusion/blob/main/datafusion/common/src/config.rs#L152) is where we generate the warning. This warning is erroneous and confusing to the user. ### To Reproduce Create a config. Set this value to the same as it already has. Warning will be generated. ### Expected behavior We probably *do* want the warning any time a user tries to set the variable, even if to the default. So instead what we may want to do is when creating a session config from a hash table of key/value pairs remove any that are not the same as the defaults. ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
