Summary

Tinybird Scheduled Copy Pipes can use temporary dedicated ClickHouse compute by adding `ON_DEMAND_COMPUTE true` to their datafiles, isolating resource-intensive scheduled transformations from a workspace’s primary compute resources. Copy Pipes periodically run queries and write results to target Data Sources, supporting append mode for incremental rollups and replace mode for current-state snapshots, with common uses including CDC deduplication, event aggregation, and snapshot creation. The setting applies only to scheduled runs, while manually triggered runs require the `--on-demand-compute` CLI flag in either Forward or Classic, and users must update their CLI to support the syntax. Positioned as a batch-oriented complement to incremental Materialized Views, Copy Pipes can build broader historical views that may be combined with recent data in a lambda architecture. On-demand compute is available on paid plans, uses a default 64-core instance, and is billed by compute time in region-dependent credits; because provisioning adds startup overhead, it is intended for larger or overlapping jobs whose resource demands justify dedicated capacity rather than for every scheduled query.
