When we create a DataBrew project and refer to the Dataset based on JDBC connection we find that the RDS(MySQL database) executes the query=> select * from table. But our table contains huge data. Why is the complete data being loaded ?. Can we restrict loading all data. Because loading whole data in DataBrew project is huge concern for us. But we see that DataBrew Project has Default sample size 500 records to load. Our main concern is why is the query (Select * From table) is sent to the rds.
