Background jobs

Blobscan requires BullMQ to run the following tasks in the background:

• SwarmStampSyncer - updates TTL for Ethereum Swarm batches.
• ETHPriceSyncer - gets the ETH price in USD and stores it.

For more information, check out the @blobscan/syncers package.

The BullMQ queue is also used to upload blobs in parallel to different Storages.

Metrics

Dagster calculates the metrics for the charts and the totals (for example, Total Tx Fees Saved, Total Blocks and Total Blobs). The pipeline writes the metrics to the hourly_metrics, daily_metrics, weekly_metrics, monthly_metrics, yearly_metrics and all_time_metrics tables. The API reads the metrics from these tables.

For more information, refer to the apps/dagster README.
