Number type of Oracle don't right with data type of Iceberg table

[duc-dn]

• I am ingesting data from oracle to iceberg table. This is data types of source table in my oracle

• And this is data types in iceberg table.

• Data in iceberg table

• I see that number datatype in oracle don't right with data type of iceberg table

@duc-dn by default NUMBER is mapped by debezium. you could use decimal.handling.mode debezium configuration to enforce different handling.

Thanks @ismailsimsek, I added "debezium.source.decimal.handling.mode": "double" and resolved this problem

Hi @ismailsimsek, I tried to cdc with a higher version of Oracle (19) and got the error below. After I ran with Postgres, MySql, I got the same error. Before that, I was still able to run cdc with Postgres, MySql without any problem and I didn't change anything about my docker image.
