Feature Description

The disk throughput throttling parameter for the Fast Online DDL ingest behind mode is used to limit the read/write throughput consumed during the data backfilling phase, which means neither read nor write operations will exceed this value. This parameter affects the execution efficiency of Fast Online DDL. Setting it to 0 disables throttling.
