Dependency Conflict: dagster-sqlmesh and dlt[pyiceberg] Incompatible Due to pyarrow Version Requirements

[vndv]

I am encountering a dependency conflict when trying to install dagster-sqlmesh alongside dlt[pyiceberg]. The issue arises due to incompatible version requirements for the pyarrow package.

No solution found when resolving dependencies:
  ╰─▶ Because only the following versions of pyarrow are available:
          pyarrow<=18.0.0
          pyarrow==18.1.0
          pyarrow==19.0.0
      and dlt[pyiceberg]==1.6.1 depends on pyarrow>=18.0.0, we can conclude that
      dlt[pyiceberg]==1.6.1 depends on pyarrow>=18.0.0.
      And because all versions of dagster-sqlmesh depend on pyarrow>=17.0.0,<18.0.0 and only
      dlt[pyiceberg]<=1.6.1 is available, we can conclude that all versions of dagster-sqlmesh and
      dlt[pyiceberg]>=1.6.1 are incompatible.
      And because your project depends on dagster-sqlmesh and dlt[pyiceberg]>=1.6.1, we can conclude
      that your project's requirements are unsatisfiable.

Expected Behavior

The dependencies should resolve successfully, allowing both dagster-sqlmesh and dlt[pyiceberg] to be installed in the same environment.

Actual Behavior

The dependency resolver fails due to incompatible pyarrow version requirements:

• dagster-sqlmesh requires pyarrow>=17.0.0,<18.0.0.
• dlt[pyiceberg] requires pyarrow>=18.0.0.

Environment

• Python Version: >=3.13
• Package Manager: uv
• Operating System: macOS

Additional Context

This issue prevents me from using both dagster-sqlmesh and dlt[pyiceberg] in the same project. I need both packages for my workflow, and resolving this conflict is critical.
