Check The Ingestion Status

When a new source is created, Materialize performs a sync of all data available in the upstream Kafka topic before it starts ingesting new data — an operation known as _snapshotting_. Because the initial snapshot is persisted in the storage layer atomically (i.e., at the same ingestion timestamp), you will **not able to query the source until snapshotting is complete**. In this step, you'll monitor the progress of the initial snapshot using the observability features in the Materialize Console. 1. If not already logged in, log in to the Materialize Console. 1. Navigate to **Monitoring** > **Sources** and click through to the source you created in the previous step. In the source overview page, you will see a progress bar with the status and progress of the snapshot. 1. For the duration of the snapshotting operation, the source status will show as Snapshotting. Once the source status transitions from Snapshotting to Running, the source is ready for querying and you can move on to the next step. If the source fails to transition to this state, check the ingestion troubleshooting guide.
