Use CData Sync for automated, continuous, customizable Presto replication to Microsoft Access.

Always-on applications rely on automatic failover capabilities and real-time data access. CData Sync integrates live Presto data into your Microsoft Access instance, allowing you to consolidate all of your data into a single location for archiving, reporting, analytics, machine learning, artificial intelligence and more.

About Presto Data Integration

Accessing and integrating live data from Trino and Presto SQL engines has never been easier with CData. Customers rely on CData connectivity to:

  • Access data from Trino v345 and above (formerly PrestoSQL) and Presto v0.242 and above (formerly PrestoDB)
  • Read and write access all of the data underlying your Trino or Presto instances
  • Optimized query generation for maximum throughput.

Presto and Trino allow users to access a variety of underlying data sources through a single endpoint. When paired with CData connectivity, users get pure, SQL-92 access to their instances, allowing them to integrate business data with a data warehouse or easily access live data directly from their preferred tools, like Power BI and Tableau.

In many cases, CData's live connectivity surpasses the native import functionality available in tools. One customer was unable to effectively use Power BI due to the size of the datasets needed for reporting. When the company implemented the CData Power BI Connector for Presto they were able to generate reports in real-time using the DirectQuery connection mode.


Getting Started


Configure Microsoft Access as a Replication Destination

Using CData Sync, you can replicate Presto data to Microsoft Access. To add a replication destination, navigate to the Connections tab.

  1. Click Add Connection.
  2. Select Microsoft Access as a destination. 👁 Configure a Destination connection to Microsoft Access.
  3. Enter the necessary connection properties. To connect to Microsoft Access, set the following:
    • Data Source: The path to the Access database. The application must have read/write permissions to the database.
    • Provider: The OLEDB Provider. For MS Office 2007 and above, use Microsoft.ACE.OLEDB.12.0.

    Windows Edition

    Connecting to Access as a destination requires the Microsoft Access Database Engine, which can be downloaded from here.

    Be sure to download the correct bitness of the driver as 64bit MS Office only works with the 64bit driver. If using 32bit MS Office, you will need to host DataSync in IIS and enable 32-bit applications. This can be set in the "Advanced Settings" for you Application Pool. Refer to Configuration in IIS for more information on hosting DataSync in IIS.

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

Configure the Presto Connection

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

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

    Set the Server and Port connection properties to connect, in addition to any authentication properties that may be required.

    To enable TLS/SSL, set UseSSL to true.

    Authenticating with LDAP

    In order to authenticate with LDAP, set the following connection properties:

    • AuthScheme: Set this to LDAP.
    • User: The username being authenticated with in LDAP.
    • Password: The password associated with the User you are authenticating against LDAP with.

    Authenticating with Kerberos

    In order to authenticate with KERBEROS, set the following connection properties:

    • AuthScheme: Set this to KERBEROS.
    • KerberosKDC: The Kerberos Key Distribution Center (KDC) service used to authenticate the user.
    • KerberosRealm: The Kerberos Realm used to authenticate the user with.
    • KerberosSPN: The Service Principal Name for the Kerberos Domain Controller.
    • KerberosKeytabFile: The Keytab file containing your pairs of Kerberos principals and encrypted keys.
    • User: The user who is authenticating to Kerberos.
    • Password: The password used to authenticate to Kerberos.
    👁 Configuring a Source connection (Salesforce is shown).
  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.

👁 Select Source and Destination connections for the 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.

👁 Choose entire tables to replicate (Salesforce is shown).

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. 👁 Configure a replication Transform.

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.

👁 Schedule your job to run automatically.

Once you have configured the replication job, click Save Changes. You can configure any number of jobs to manage the replication of your Presto data to Microsoft Access.
