Configure an Apache™ Cassandra® database connection by creating a Cassandra data source, setting the Cassandra connection options, and saving the data source.

Create a Cassandra data source for a Cassandra database connection.

vendor = "Cassandra";
opts = databaseConnectionOptions("native",vendor)
opts = 
  CassandraConnectionOptions with properties:

              DataSourceName: ""
                      Vendor: "Cassandra"

               ContactPoints: "localhost"
                  PortNumber: 9042
                  SSLEnabled: false
                LoginTimeout: 5
              RequestTimeout: 12

opts is an CassandraConnectionOptions object with these properties:

  • DataSourceName — Name of the data source

  • Vendor — Database vendor name

  • ContactPoints — Contact points

  • PortNumber — Port number

  • SSLEnabled — SSL-enabled connection

  • LoginTimeout — Login timeout

  • RequestTimeout — Request timeout

Configure the data source by setting the Cassandra connection options for the data source CassandraDataSource, local host address for one node in the cluster, port number 9042, SSL encryption that is disabled, login timeout of 5 seconds, and request timeout of 12 seconds.

opts = setoptions(opts, ...
    "DataSourceName","CassandraDataSource", ...
    "ContactPoints","localhost","PortNumber",9042, ...
    "SSLEnabled",false,"LoginTimeout",5, ...
    "RequestTimeout",12)
opts = 
  CassandraConnectionOptions with properties:

              DataSourceName: "CassandraDataSource"
                      Vendor: "Cassandra"

               ContactPoints: "localhost"
                  PortNumber: 9042
                  SSLEnabled: false
                LoginTimeout: 5
              RequestTimeout: 12

The setoptions function sets the DataSourceName, ContactPoints, PortNumber, SSLEnabled, LoginTimeout, and RequestTimeout properties in the CassandraConnectionOptions object.

Test the database connection with a blank user name and password. The testConnection function returns the logical 1, which indicates the database connection is successful.

username = "";
password = "";
status = testConnection(opts,username,password)
status = logical
   1

Save the configured data source.

saveAsDataSource(opts)

Input Arguments

Database connection options, specified as a CassandraConnectionOptions object.

Cassandra database connection options to set, specified as one or more name-value pair arguments. Option is a character vector or string scalar that specifies the name of a Cassandra database connection option. OptionValue specifies the value of the Cassandra database connection option. OptionValue can be a character vector, string scalar, logical scalar, or numeric scalar. You can specify any Cassandra database connection option that is a property of the CassandraConnectionOptions object.

Example: "DataSourceName","myDataSource","ContactPoints","localhost","PortNumber",9042 configures a Cassandra data source named myDataSource that is located on the local host address with the port number 9042.
