Automated Continuous Google Sheets Replication to Apache Cassandra

Use CData Sync for automated, continuous, customizable Google Sheets replication to Apache Cassandra.

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Google Sheets 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 Google Sheets data to Apache Cassandra. To add a replication destination, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select Apache Cassandra as a destination.
  3. 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.

  4. Click Test Connection to ensure that the connection is configured properly.
  5. Click Save Changes.

Configure the Google Sheets Connection

You can configure a connection to Google Sheets from the Connections tab. To add a connection to your Google Sheets account, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select a source (Google Sheets).
  3. Configure the connection properties.

    You can connect to a spreadsheet by providing authentication to Google and then setting the Spreadsheet connection property to the name or feed link of the spreadsheet. If you want to view a list of information about the spreadsheets in your Google Drive, execute a query to the Spreadsheets view after you authenticate.

    ClientLogin (username/password authentication) has been officially deprecated since April 20, 2012 and is now no longer available. Instead, use the OAuth 2.0 authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

    OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

    See the Getting Started chapter in the help documentation to connect to Google Sheets from different types of accounts: Google accounts, Google Apps accounts, and accounts using two-step verification.

  4. Click Connect to ensure that the connection is configured properly.
  5. 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 Transform feature to customize your replication. The Transform feature allows you to specify which columns to replicate, rename the columns at the destination, and even perform operations on the source data before replicating. To customize your replication, click the Transform button in the Tables section and customize 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 15 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 Google Sheets data to Apache Cassandra.
