Mysql JDBC Batch data, need to add rewritebatchedstatements=true to JDBC connection. The default JDBC is not to turn on batch processing.

Example: Jdbc:mysql://10.250.4.98:3306/dbname rewritebatchedstatements=true

MySQL itself have no real "batch" API for prepared statements. If You add the configuration property "Rewritebatchedstatements=true" to your JDBC connection string for connector/j, the Driver would rewrite batches of prepared inserts into Multi-value form, and all other forms of statements into Multi-statem Ents, which does give a large performance gain (7-10x).

Attention:

JDBC driver version requires 5.1.8 and above
