Estimate how long a batch will take and whether it fits the available processing window.

How to use this tool
The estimate assumes workers scale efficiently. Real throughput may be constrained by source queries, locks, network transfer, target writes, validation, commit size and skew.
Leave margin for retries, reconciliation and upstream delay. A batch that consumes nearly the entire window is operationally fragile.
Planning estimate only. Validate assumptions with workload tests, vendor documentation, architecture review and production monitoring. Browser calculations are not professional engineering or procurement advice.
