Description
WARN CommonRdbmsWriter$Task - 回滚此次写入, 采用每次写入一行方式提交. 因为:The new agreement is not binding parameters over 256, can be modified to perform the old agreement

Research direction
Start from the CommonRdbmsWriter.Task warning and reproduce the behavior with a table containing more than 256 columns. Trace why parameter binding falls back to one-row-at-a-time commits when the new protocol is used, then verify that the intended write mode works without the warning.
