Before report a bug, make sure you have:
- Searched open and closed [GitHub
issues](https://github.com/apache/shardingsphere/issues).
- Read documentation: [ShardingSphere
Doc](https://shardingsphere.apache.org/document/current/en/overview).
Please pay attention on issues you submitted, because we maybe need more
details.
If no response anymore and we cannot reproduce it on current information, we
will **close it**.
Please answer these questions before submitting your issue. Thanks!
### Which version of ShardingSphere did you use?
apache-shardingsphere-5.3.0-shardingsphere-proxy-bin
### Which project did you use? ShardingSphere-JDBC or ShardingSphere-Proxy?
ShardingSphereProxy
### Expected behavior
DATA MIGRATION success
### Actual behavior
DATA MIGRATION fail
### Reason analyze (If you can)
It is suspected that the program itself is wrong. The config-sharding.yaml
configuration file can be used to partition correctly, and the data insertion
is also correct. Only an exception occurred during data migration.
### Steps to reproduce the behavior, such as: SQL to execute, sharding rule
configuration, when exception occur etc.
1. config-sharding.yaml
databaseName: sharding_db
dataSources:
ds_0:
url:
jdbc:mysql://xxx:3306/db1?useUnicode=true&autoReconnect=true&characterEncoding=utf8
username: root
password: xxx
connectionTimeoutMilliseconds: 30000
idleTimeoutMilliseconds: 60000
maxLifetimeMilliseconds: 1800000
maxPoolSize: 50
minPoolSize: 1
ds_1:
url:
jdbc:mysql://xxx:3306/db2?useUnicode=true&autoReconnect=true&characterEncoding=utf8
username: root
password: xxx
connectionTimeoutMilliseconds: 30000
idleTimeoutMilliseconds: 60000
maxLifetimeMilliseconds: 1800000
maxPoolSize: 50
minPoolSize: 1
ds_2:
url:
jdbc:mysql://xxx:3306/db3?useUnicode=true&autoReconnect=true&characterEncoding=utf8
username: root
password: xxx
connectionTimeoutMilliseconds: 30000
idleTimeoutMilliseconds: 60000
maxLifetimeMilliseconds: 1800000
maxPoolSize: 50
minPoolSize: 1

2. Configure the source storage units in proxy.
REGISTER MIGRATION SOURCE STORAGE UNIT source1 (
URL="jdbc:mysql://xxx:3306/db5?serverTimezone=UTC&useSSL=false",
USER="root",
PASSWORD="xxx",
PROPERTIES("minPoolSize"="1","maxPoolSize"="20","idleTimeout"="60000")
);
3. Start data migration.
MIGRATE TABLE source1 .table1 INTO table1;
