Use CData Sync for automated, continuous, customizable Azure Analysis Services replication to Apache Cassandra.
Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Azure Analysis Services data into your Apache Cassandra instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.
Configure Cassandra as a Replication Destination
Using CData Sync, you can replicate Azure Analysis Services data to Apache Cassandra. To add a replication destination, navigate to the Connections tab.
- Click Add Connection.
- Select Apache Cassandra as a destination.
Enter the necessary connection properties. CData Sync supports Basic authentication with login credentials and the additional authentication features of DataStax Enterprise (DSE) Cassandra. The following sections detail connection properties your authentication method may require.
You need to set AuthScheme to the value corresponding to the authenticator configured for your system. You specify the authenticator in the authenticator property in the cassandra.yaml file. This file is typically found in /etc/dse/cassandra or through the DSE Unified Authenticator on DSE Cassandra.
Basic Authentication
Basic authentication is supported through Cassandra's built-in default PasswordAuthenticator.
- Set the AuthScheme property to 'BASIC' and set the User and Password properties.
- In the cassandra.yaml file, set the authenticator property to 'PasswordAuthenticator.'
Kerberos Authentication
Kerberos authentication is supported through DataStax Enterprise Unified Authentication.
- Set the AuthScheme property to 'KERBEROS' and set the User and Password properties.
- Set the KerberosKDC, KerberosRealm, and KerberosSPN properties.
- In the cassandra.yaml file, set the authenticator property to "com.datastax.bdp.cassandra.auth.DseAuthenticator."
- Modify the authentication_options section in the dse.yaml file, specifying the default_schema and other_schemas properties as 'kerberos.'
- Modify the kerberos_options section in the dse.yaml file, specifying the keytab, service_principle, http_principle and qop properties.
LDAP Authentication
LDAP authentication is supported through DataStax Enterprise Unified Authentication.
- Set the AuthScheme property to 'LDAP' and set the User and Password properties.
- In the cassandra.yaml file, set the authenticator property to "com.datastax.bdp.cassandra.auth.DseAuthenticator."
- Modify the authentication_options section in the dse.yaml file, specifying the default_schema and other_schemas properties as 'ldap.'
- Modify the ldap_options section in the dse.yaml file, specifying the server_host, server_port, search_dn, search_password, user_search_base, and user_search_filter properties.
Using PKI
You can specify a client certificate to authenticate CData Sync with SSLClientCert, SSLClientCertType, SSLClientCertSubject, and SSLClientCertPassword.
- Click Test Connection to ensure that the connection is configured properly.
- Click Save Changes.
Configure the Azure Analysis Services Connection
You can configure a connection to Azure Analysis Services from the Connections tab. To add a connection to your Azure Analysis Services account, navigate to the Connections tab.
- Click Add Connection.
- Select a source (Azure Analysis Services).
- Configure the connection properties.
To connect to Azure Analysis Services, set the Url property to a valid server, for instance, asazure://southcentralus.asazure.windows.net/server, in addition to authenticating. Optionally, set Database to distinguish which Azure database on the server to connect to.
Azure Analysis Services uses the OAuth authentication standard. OAuth requires the authenticating user to interact with Azure Analysis Services using the browser. You can connect without setting any connection properties for your user credentials. See the Help documentation for more information.
- Click Connect to ensure that the connection is configured properly.
- Click Save Changes.
Configure Replication Queries
CData Sync enables you to control replication with a point-and-click interface and with SQL queries. For each replication you wish to configure, navigate to the Jobs tab and click Add Job. Select the Source and Destination for your replication.
Replicate Entire Tables
To replicate an entire table, click Add Tables in the Tables section, choose the table(s) you wish to replicate, and click Add Selected Tables.
Customize Your Replication
You can use the Columns and Query tabs of a task to customize your replication. The Columns tab allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. The Query tab allows you to add filters, grouping, and sorting to the replication.Schedule Your Replication
In the Schedule section, you can schedule a job to run automatically, configuring the job to run after specified intervals ranging from once every 10 minutes to once every month.
Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your Azure Analysis Services data to Apache Cassandra.
