)CassandraConnectionOptions
object opts
.
Examples
Create Cassandra Data Source and Set Connection Options
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 sourceVendor
— Database vendor nameContactPoints
— Contact pointsPortNumber
— Port numberSSLEnabled
— SSL-enabled connectionLoginTimeout
— Login timeoutRequestTimeout
— 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
opts
— Database connection options
CassandraConnectionOptions
object
Database connection options, specified as a CassandraConnectionOptions
object.
Option1,OptionValue1,...,OptionN,OptionValueN
— Cassandra database connection options to set
name-value pair arguments
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
.
Output Arguments
opts
— Database connection options
CassandraConnectionOptions
object
Database connection options, returned as a CassandraConnectionOptions
object.
