Hey @Irakli Gugushvili, could you elaborate what you mean by Batch Processing? So Prefect is definitely a batch orchestrator compared to other platforms that work with data streams.
Parent and child flows is one way to do batch processing where the parent can get a list of batches to process, and then kick off child flows for each one.
If you are talking about incremental pulls from a database, and then just processing deltas, the KV Store is our mechanism for that where you can persist metadata like the last processed timestamp and then process the new data
