jdbc [string]

In addition to the parameters that must be specified above, users can also specify multiple optional parameters, which cover all the parameters provided by Spark JDBC.

The way to specify parameters is to add the prefix jdbc. to the original parameter name. For example, the way to specify fetchsize is: jdbc.fetchsize = 50000 . If these non-essential parameters are not specified, they will use the default values given by Spark JDBC.

password [string]

password

table [string]

table name

url [string]

The URL of the JDBC connection. Refer to a case: jdbc:postgresql://localhost/test

user [string]

jdbc {
    driver = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://localhost:3306/info"
    table = "access"
    result_table_name = "access_log"
    user = "username"
    password = "password"
}

Read MySQL data through JDBC

jdbc {
    driver = "com.mysql.jdbc.Driver"
    url = "jdbc:mysql://localhost:3306/info"
    table = "access"
    result_table_name = "access_log"
    user = "username"
    password = "password"
    jdbc.partitionColumn = "item_id"
    jdbc.numPartitions = "10"
    jdbc.lowerBound = 0
    jdbc.upperBound = 100
}

Divide partitions based on specified fields
