Skip to main contentPrequel Import is designed to support extremely high volumes of data. To support these high volumes, a few advanced configuration options may be useful, or in some cases, necessary.
Updated At column
For volumes exceeding ~10m rows, an explicit Updated At column that records the time that the row was last modified significantly improves change detection performance.
Batch API Destination type
If the target Destination endpoint is expected to recieve more than ~10m rows per day for any Provider, we strongly recommend using the Batch API Destination type for increased efficiency.
Resource tuning
By default, your Prequel Import account is provisioned with a default hardware selection for average transfer workloads. However, there are cases where the underlying infrastructure must be tuned to properly support workloads that are significantly larger than average. Please contact your Prequel Representative if you suspect this may be applicable to your use case.
