### Bootstrap Procedure

The snapshot pipes use **append COPY MODE**. This means running a snapshot pipe will add rows to the existing datasource rather than replacing it. To recreate the buckets from scratch, follow these steps for each bucket `#` (0–9):

1. **Prepare**: Ensure all bucket datasources exist
2. **Execute Snapshots**: Run all 10 snapshot pipes manually
3. **Verify**: Check each bucket has ~10% of total records
4. **Enable Enrichment**: Allow scheduled copy pipes to run
5. **Monitor**: Watch for snapshotId updates in cleaned buckets
2. **Pause** the `activityRelations_bucket_clean_enrich_copy_pipe_#` pipe
3. **Truncate** `activityRelations_bucket_MV_ds_#`
4. **Run** the `activityRelations_bucket_MV_snapshot_#` pipe
5. **Confirm** that `activityRelations_bucket_MV_ds_#` was populated and has 10% of total records
6. **Resume** the `activityRelations_bucket_clean_enrich_copy_pipe_#` pipe
7. **Monitor**: Watch for snapshotId updates in cleaned buckets

> **Why pause the enrichment pipe first?** The enrichment copy pipe reads from `activityRelations_bucket_MV_ds_#`. Truncating while it runs could cause it to produce empty or partial results. Pausing ensures a clean window for the snapshot to populate the datasource.
