# Proposed changes
1. In previous versions, encountering a source schema that did not match
Doris would lead to the failure of the entire job. This was especially
problematic when dealing with source instances containing thousands of tables.
Moreover, adding a new table to the source database with a schema incompatible
with Doris would also cause the job to fail. To address this issue, we
introduced the `--ignore-incompatible "true/false"` option. When set to true,
incompatible schemas are ignored, whereas setting it to false triggers an error
for mismatched schemas. The default value of `--ignore-incompatible` is true.
For example, we create tables `AA\C` and `#1234` in Oracle, but their
schemas do not match those in Doris.
We run in the Flink CLI in the following way:
```
<FLINK_HOME>bin/flink run \
-Dexecution.checkpointing.interval=10s \
-Dparallelism.default=1 \
-c org.apache.doris.flink.tools.cdc.CdcTools \
lib/flink-doris-connector-1.17-1.6.0-SNAPSHOT.jar \
mysql-sync-database \
--database test_db \
--mysql-conf hostname=127.0.0.1 \
--mysql-conf port=3306 \
--mysql-conf username=root \
--mysql-conf password=123456 \
--mysql-conf database-name=mysql_db \
--including-tables "tbl1|test.*" \
--sink-conf fenodes=127.0.0.1:8030 \
--sink-conf username=root \
--sink-conf password=123456 \
--sink-conf jdbc-url=jdbc:mysql://127.0.0.1:9030 \
--sink-conf sink.label-prefix=label \
--table-conf replication_num=1 \
--single-sink "true" \
--use-new-schema-change "true" \
--ignore-incompatible "true"
```
3. We have refactored the DorisSystem createTable DDL code.
