 **Solution**:
 
-Currently, the limitation of TiDB cannot be bypassed. You can only ignore this table to ensure the successful import of other tables.
+- Use the [`tidb_txn_entry_size_limit`](/system-variables.md#tidb_txn_entry_size_limit-new-in-v760) system variable to dynamically increase the limit.
+- Note that TiKV has a similar limit. If the data size of a single write request exceeds [`raft-entry-max-size`](/tikv-configuration-file.md#raft-entry-max-size) (`8MiB` by default), TiKV refuses to process this request. When a table has a row of a large size, you need to modify both configurations.
