Supported Databases for JDBC

Following databases are supported via Spark JDBC by default:

DB2
MySQL / MariaDB
MS Sql
Oracle
PostgreSQL

Prerequisites

Required JAR files

These templates requires the JDBC jar file to be available in the Dataproc cluster. User has to download the required jar file and host it inside a Cloud Storage Bucket, so that it could be referred during the execution of code.

wget command to download JDBC jar file is as follows :-

MySQL

wget http://dev.mysql.com/get/Downloads/Connector-J/mysql-connector-java-5.1.30.tar.gz

PostgreSQL

wget https://jdbc.postgresql.org/download/postgresql-42.2.6.jar

Microsoft SQL Server

wget https://repo1.maven.org/maven2/com/microsoft/sqlserver/mssql-jdbc/6.4.0.jre8/mssql-jdbc-6.4.0.jre8.jar

Oracle

wget https://repo1.maven.org/maven2/com/oracle/database/jdbc/ojdbc8/21.7.0.0/ojdbc8-21.7.0.0.jar

Once the jar file gets downloaded, please upload the file into a Cloud Storage Bucket and export the below variable

export JARS=<gcs-bucket-location-containing-jar-file>

JDBC URL syntax

MySQL

jdbc:mysql://<hostname>:<port>/<dbname>?user=<username>&password=<password>

PostgreSQL

jdbc:postgresql://<hostname>:<port>/<dbname>?user=<username>&password=<password>

Microsoft SQL Server

jdbc:sqlserver://<hostname>:<port>;databaseName=<dbname>;user=<username>;password=<password>

Oracle

jdbc:oracle:thin:@//<hostname>:<port>/<dbservice>?user=<username>&password=<password>

Note: JDBC Connections now allow use of secrets created in Cloud Secret Manager. Please check the examples in respective sections.

Other important properties

Driver Class

MySQL

jdbctojdbc.input.driver="com.mysql.cj.jdbc.Driver"

PostgreSQL

jdbctojdbc.input.driver="org.postgresql.Driver"

Microsoft SQL Server

jdbctojdbc.input.driver="com.microsoft.sqlserver.jdbc.SQLServerDriver"

Oracle

jdbctojdbc.input.driver="oracle.jdbc.driver.OracleDriver"

You can either specify the source table name or have SQL query within double quotes. Example,

jdbctojdbc.input.table="employees"
jdbctojdbc.input.table="(select * from employees where dept_id>10) as employees"

partitionColumn, lowerBound, upperBound and numPartitions must be used together. If one is specified then all needs to be specified.
Additional execution details refer spark jdbc doc

1. JDBC To JDBC

Template for reading data from JDBC table and writing them to a JDBC table. It supports reading partition tabels and write into partitioned or non-partitioned tables.

Arguments

jdbctojdbc.input.url: JDBC input URL
jdbctojdbc.input.url.secret: JDBC input URL secret. Pass the secret name as created in Cloud Secret Manager

Note: Please provide only one of the above two properties (jdbctojdbc.input.url or jdbctojdbc.input.url.secret)

jdbctojdbc.input.driver: JDBC input driver name
jdbctojdbc.input.table: JDBC input table name
jdbctojdbc.output.url: JDBC output url. When the JDBC target is PostgreSQL it is recommended to include the connection parameter reWriteBatchedInserts=true in the URL to provide a significant performance improvement over the default setting. OR provide secret name enclosed inside { }
jdbctojdbc.output.url.secret: JDBC output URL secret. Pass the secret name as created in Cloud Secret Manager.

Note: Please provide only one of the above two properties (jdbctojdbc.output.url or jdbctojdbc.output.url.secret)

jdbctojdbc.output.table: JDBC output table name
jdbctojdbc.input.partitioncolumn (Optional): JDBC input table partition column name
jdbctojdbc.input.lowerbound (Optional): JDBC input table partition column lower bound which is used to decide the partition stride
jdbctojdbc.input.upperbound (Optional): JDBC input table partition column upper bound which is used to decide the partition stride
jdbctojdbc.numpartitions (Optional): The maximum number of partitions that can be used for parallelism in table reading and writing. Same value will be used for both input and output jdbc connection. Default set to 10
jdbctojdbc.input.fetchsize (Optional): Determines how many rows to fetch per round trip
jdbctojdbc.input.sessioninitstatement (Optional): Custom SQL statement to execute in each reader database session
jdbctojdbc.output.create_table.option (Optional): This option allows setting of database-specific table and partition options when creating a output table

MySQL

There are two optional properties as well with "JDBC to JDBC" Template. Please find below the details :-

--templateProperty jdbctojdbc.temp.view.name='temporary_view_name'
--templateProperty jdbctojdbc.sql.query='select * from global_temp.temporary_view_name'

These properties are responsible for applying some spark sql transformations before loading data into JDBC. The only thing needs to keep in mind is that, the name of the Spark temporary view and the name of table in the query should match exactly. Otherwise, there would be an error as:- "Table or view not found:"

There are two optional properties as well with "JDBC to Cloud Storage" Template. Please find below the details :-

--templateProperty jdbctogcs.temp.view.name='temporary_view_name'
--templateProperty jdbctogcs.temp.sql.query='select * from global_temp.temporary_view_name'

These properties are responsible for applying some spark sql transformations before loading data into Cloud Storage. The only thing needs to keep in mind is that, the name of the Spark temporary view and the name of table in the query should match exactly. Otherwise, there would be an error as:- "Table or view not found:"

3. JDBC To BigQuery

Template for reading data from JDBC table and writing into files in Google Cloud BigQuery. It supports reading partition tables.

Arguments
