Summary0004783: Initial load can slow down when batches on other channels cause conflict resolution
DescriptionInitial load batches should load as winning rows in any conflict detection. The row capture time is not sent in initial load batches, which means the rows should always win. However, if batches from a higher priority channel, like the "config" channel, are sent first during a push/pull, then the row capture time can be set and used on initial load batches. On a busy system, the initial load can encounter many conflicts due to the timing of extraction, so the overhead of determining winning rows can slow it down. Clear the row capture time at the beginning of each batch.
