> @hongbofan If you do not want to add the SPI Services file, you can also
specify the full path of the custom algorithm with `CLASS BASED` type. The
following is an example

this way i create sharding algorithm,
CREATE SHARDING ALGORITHM source_date_complex (
TYPE(NAME=CLASS_BASED,PROPERTIES("defTable"="o2pcm_multimedia","sources"="mall,customer","strategy"="COMPLEX","algorithmClassName"="com.qx.agg.client.sharding.SourceDateComplexShardingAlgorithm"))
);
get a error message
