+    NOTE: To force the model to run every time, set `allow_partials` to `true` and use the `--ignore-cron` argument: `sqlmesh run --ignore-cron`. Simply setting `allow_partials` to `true` does not guarantee that the model will run on every `sqlmesh run` command invocation. The model’s configured `cron` schedule is still respected, even when partial intervals are allowed.

Depending on the time of day, the interval might not be complete and ready for execution, even when ignoring the `cron` schedule. Therefore, both are required to ensure that the model runs on every `sqlmesh run` invocation.
