-- This variable only takes effect when index creation acceleration is enabled (by [`tidb_ddl_enable_fast_reorg`](#tidb_ddl_enable_fast_reorg-new-in-v630)). It limits the bandwidth in which writing data into each TiKV. The default value `0` means no writing limitation. The default unit is bytes per second. You can also set this variable to values like `'1GiB'`, `'256MiB`.
+- Range: `[0, 1125899906842624]` (the maximum value that can be set is 1 PiB)
+- This variable only takes effect when index creation acceleration is enabled (controlled by the [`tidb_ddl_enable_fast_reorg`](#tidb_ddl_enable_fast_reorg-new-in-v630) variable). It limits the write bandwidth for each TiKV node. The default value `0` means no write bandwidth limit. The default unit is bytes per second. You can also set the value in formats such as `'1GiB'` or `'256MiB`.
