Consultar o MariaDB com o Databricks
Este exemplo consulta o MariaDB usando seu driver JDBC. Para obter mais detalhes sobre leitura, gravação, configuração de paralelismo e pushdown de consulta, consulte Consulta a bancos de dados usando JDBC.
Criar o URL do JDBC
- Python
- Scala
Python
driver = "org.mariadb.jdbc.Driver"
database_host = "<database-host-url>"
database_port = "3306" # update if you use a non-default port
database_name = "<database-name>"
table = "<table-name>"
user = "<username>"
password = "<password>"
url = f"jdbc:mariadb://{database_host}:{database_port}/{database_name}"
Scala
val driver = "org.mariadb.jdbc.Driver"
val database_host = "<database-host-url>"
val database_port = "3306" # update if you use a non-default port
val database_name = "<database-name>"
val table = "<table-name>"
val user = "<username>"
val password = "<password>"
val url = s"jdbc:mariadb://${database_host}:${database_port}/${database_name}"
Consulte a tabela remota
- Python
- Scala
Python
remote_table = (spark.read
.format("jdbc")
.option("driver", driver)
.option("url", url)
.option("dbtable", table)
.option("user", user)
.option("password", password)
.load()
)
Scala
val remote_table = spark.read
.format("jdbc")
.option("driver", driver)
.option("url", url)
.option("dbtable", table)
.option("user", user)
.option("password", password)
.load()
