Description
We can disable _metadata file generation since it is not being used anymore to reduce the memory usage during commit phase.
We are keeping the _common_metadata since it is less memory expensive.

Research direction
No file or test is named in the issue. Start by tracing _metadata generation during the commit phase, then verify where _common_metadata is retained. Done means _metadata is no longer generated, _common_metadata remains available, and the change reduces commit-phase memory usage.
