Summary0003886: Initial load foreign key error auto resolve
DescriptionWhen sending an initial load or reload batches, the data loader may receive a foreign key exception for missing rows. This can happen when changes are happening on a busy database, since each table extraction is happening at different times. The normal auto resolution for change data capture relies on the acknowledge service using sym_data for the row in error and the source database for FK references to send reload batches to fix. This doesn't work when the error is already on the reload channel and when there is nothing in sym_data to query for row data.

Instead, use the reverse logic of the dataloader service using the target database for the FK references and send a script to the source node that sends reloads on the config channel. Enabled with parameter auto.resolve.foreign.key.violation.reverse.reload=true.
