+When the cache backend is `SupersetMetastoreCache`, report execution does not
+write channel listings into the cache because that backend commits the report's
+database session. Schedule the dedicated warm-up task so cache misses are
+repopulated outside report transactions:
+
+```python
+from celery.schedules import crontab
+
+class CeleryConfig:
+ beat_schedule = {
+ "slack.cache_channels": {
+ "task": "slack.cache_channels",
+ "schedule": crontab(minute="0", hour="*"),
+ },
Review Comment:
Fixed in `bdbdb4fcae` — the example now subclasses Superset’s default
`CeleryConfig`, extends `CeleryConfig.beat_schedule`, and assigns
`CELERY_CONFIG`, so the built-in report and maintenance entries are preserved.
