ODBC is one of the most established and widely supported APIs for connecting to and working with databases. The Kyvos ODBC Driver is used for Spark SQL access to the Kyvos BI Server, enabling business intelligence, analytics, and reporting.

The driver is currently available for Microsoft Windows® 64-bit platform. This Driver complies with the ODBC 3.80 data standard.

Click here to download the Kyvos ODBC driver.

Features

The Kyvos ODBC driver comes with the following features.

  • Catalog and schema support: The Kyvos ODBC Driver supports both catalogs and schemas to make it easy for the driver to work with various ODBC applications.

  • Security and authentication: Some Kyvos datastores require connections authentication with Secure Sockets Layer (SSL) protocol to protect data from unauthorized access. SSL encryption protects data and credentials when they are transferred over the network and provides stronger security. We recommended enabling SSL whenever you connect to a server that is configured to support it.
    For more information, refer to the Configuring SSL Verification on Windows section below.

    2. To use the Windows Trust Store, select the Use System Trust Store checkbox.

Important

If using Windows Trust Store, you MUST import the trusted CA certificates to the Trust Store.

Configuring logging options on Windows

To help troubleshoot issues, you can configure logging settings for the driver. In addition to the functionality provided in the Kyvos ODBC Driver, the ODBC Data Source Administrator provides tracing functionality.

Important

Logging or tracing decreases performance and can consume a large quantity of disk space, so make sure to keep log level as FATAL which will have a negligible impact on performance and disk space.

To configure driver logging on Windows:

  1. To access logging options, open the ODBC Data Source Administrator where you created the DSN, then select the DSN, click Configure.

  2. On the Kyvos ODBC Driver DSN Setup dialog box, click the Advance Options tab.

  3. From the Log Level drop-down list, select the logging level corresponding to the amount of information that you want to include in log files.

  4. This table enlists the information corresponding to each log level.

Logging level

Description

FATAL 

Logs severe error events that lead the driver to stop processing.

ERROR

Logs error events that might allow the driver to continue running.

WARNING

Logs events that might result in an error if no action is taken.

INFO

Logs general information that describes the progress of the driver.

DEBUG

Logs detailed information that is useful for debugging the driver.

TRACE

Logs all driver activity, including result set.

  1. In the Log Path field, specify the full path to the folder where you want to save log files.

  2. In the Max Number Files field, type the maximum number of log files to keep.

Note

After the maximum number of log files is reached, each time an additional file is created, the driver deletes the oldest log file.

  1. In the Max File Size field, type the maximum size of each log file in megabytes (MB).

Note

After the maximum file size is reached, the driver creates a new file and continues logging.

  1. Click OK.

  2. Restart your BI application for new settings to come in effect. The Kyvos ODBC Driver creates a log file named log at the location specified in the Log Path field.

Important

After Connecting using Kyvos ODBC Driver to the server, a folder named SQLLog is created at the logging path location. Under this folder, new folders are created for the current date(s), which contains the Kyvos_odbc_client_SQLLog.log file. This file captures records for all the queries sent to the Kyvos BI server.

Note

The default log level is set as FATAL, and the default location for log files is C:\ProgramData\Kyvos\Kyvos ODBC Driver\Logs. You cannot disable logging for Kyvos ODBC Driver.

Creating a data source name (DSN) on Mac OS

After installing the Kyvos ODBC driver, create a System DSN named KyvosDSN, as explained below.
You can create the DSN from the odbc.ini file or using the iODBC Administrator.

Note

MAC does not supports Kerberos authentication.

Using odbc.ini file

Navigate to /Library/ODBC folder, and edit the odbc.ini file as:

[ODBC Data Sources]
KyvosDSN       = Kyvos ODBC Driver
 
[KyvosODBC]
Description = KyvosDSN
Driver      = Kyvos ODBC Driver
Host        = start.trial.kyvosinsights.com
Port        = 8081
AuthMech	=3
UserName    = admin
HTTPPath    = kyvos/sql
SSL         = 0

Using iODBC Administrator
Enter details as mentioned above, and create the DSN as shown in the following figure.

Configuring logging options on MAC

  1. Open kyvos.odbcclient.ini file

  2. Configure the logging parameters as needed.

  3. Save the file and close.

Note

For log level related parameters, see the Configuring logging options on Windows section.

Configuring rows fetched per block

On the Kyvos ODBC Driver DSN Setup dialog, in the Properties section, for the Rows Fetched Per Column field, you need to specify the number of rows fetched in each chunk.

Note

You must provide a value ranging from 1 to 100000

To choose the limit for the chunk size that is more than 100000, you need to add a sql.hive.server2.thrift.resultset.max.fetch.size at the connection level.

To add a property, perform the following steps.

  1. Go to any created connection, and then click Properties.
    Following is the sample to explain how to add a new property at the connection level.

  2. Click the Properties link.
