IBM Cloud Object Storage Connector for CData Sync

Overview

The CData Sync App provides a straightforward way to continuously pipeline your IBM Cloud Object Storage data to any database, data lake, or data warehouse, making it easily available for Analytics, Reporting, AI, and Machine Learning.

The IBM Cloud Object Storage connector can be used from the CData Sync application to pull data from IBM Cloud Object Storage and move it to any of the supported destinations.

IBM Cloud Object Storage Version Support

The Sync App leverages the IBM Cloud Object Storage S3 API to enable bidirectional access to IBM Cloud.

Establishing a Connection

Adding a Connection to IBM Cloud Object Storage

To add a connection to IBM Cloud Object Storage:

  1. In the application console, navigate to the Connections page.
  2. At the Add Connections panel, select the icon for the connection you want to add.
  3. If the IBM Cloud Object Storage icon is not available, click the Add More icon to download and install the IBM Cloud Object Storage connector from the CData site.

For required properties, see the Settings tab.

For connection properties that are not typically required, see the Advanced tab.

Before You Connect

Before you can connect to IBM Cloud Object Storage, you need to register a IBM Cloud Object Storage instance, then find and note your IBM Cloud Object Storage API Key and CRN.

Register a New Instance of Cloud Object Storage

If you do not already have Cloud Object Storage in your IBM Cloud account, you can follow the procedure below to install an instance of SQL Query in your account:

  1. Log in to your IBM Cloud account.
  2. Navigate to the Cloud Object Storage page, choose a name for your instance and click Create. You will be redirected to the instance of Cloud Object Storage you just created.

API Key

You can obtain your ApiKey as follows:

  1. Log in to your IBM Cloud account.
  2. Navigate to the Platform API Keys page.
  3. On the middle-right corner, click Create an IBM Cloud API Key to create a new API Key.
  4. In the pop-up window, specify the API Key name and click Create. Note the API Key as you can never access it again from the dashboard.

Cloud Object Storage CRN

By default, the Sync App will attempt to automatically determine a Cloud Object Storage CRN. However, if you have multiple accounts, you will need to specify the CloudObjectStorageCRN explicitly. You can obtain this value in one of two ways:

  • Query the Services view. This will list your IBM Cloud Object Storage instances along with the CRN for each.
  • Locate the CRN directly in IBM Cloud. To do so, navigate to your IBM Cloud Dashboard. In the Resource List, under Storage, select your Cloud Object Storage resource to get its CRN.

Connecting to IBM Cloud Object Storage

You can now set the following to connect to data:

  • ApiKey: Set this to your API key which was noted during setup.
  • CloudObjectStorageCRN (Optional): Set this to your noted cloud object storage CRN. While the Sync App attempts to retrieve this automatically, specifying this explicitly is recommended if you have more than one Cloud Object Storage account.

When you connect, the Sync App completes the OAuth process.

Fine-Tuning Data Access

Fine Tuning Data Access

You can use the following properties to gain greater control over IBM Cloud Object Storage API features and the strategies the Sync App uses to surface them:

  • Region: The geographic location of the bucket you're connecting to. If specified, the Sync App won't attempt to resolve the location of the buckets.

IBM Cloud Object Storage Connector for CData Sync

Advanced Features

This section details a selection of advanced features of the IBM Cloud Object Storage Sync App.

User Defined Views

The Sync App allows you to define virtual tables, called user defined views, whose contents are decided by a pre-configured query. These views are useful when you cannot directly control queries being issued to the drivers. See User Defined Views for an overview of creating and configuring custom views.

SSL Configuration

Use SSL Configuration to adjust how Sync App handles TLS/SSL certificate negotiations. You can choose from various certificate formats; see the SSLServerCert property under "Connection String Options" for more information.

Firewall and Proxy

Configure the Sync App for compliance with Firewall and Proxy, including Windows proxies and HTTP proxies. You can also set up tunnel connections.

Query Processing

The Sync App offloads as much of the SELECT statement processing as possible to IBM Cloud Object Storage and then processes the rest of the query in memory (client-side).

See Query Processing for more information.

Logging

See Logging for an overview of configuration settings that can be used to refine CData logging. For basic logging, you only need to set two connection properties, but there are numerous features that support more refined logging, where you can select subsets of information to be logged using the LogModules connection property.

IBM Cloud Object Storage Connector for CData Sync

SSL Configuration

Customizing the SSL Configuration

By default, the Sync App attempts to negotiate SSL/TLS by checking the server's certificate against the system's trusted certificate store.

To specify another certificate, see the SSLServerCert property for the available formats to do so.

IBM Cloud Object Storage Connector for CData Sync

Firewall and Proxy

Connecting Through a Firewall or Proxy

HTTP Proxies

To connect through the Windows system proxy, you do not need to set any additional connection properties. To connect to other proxies, set ProxyAutoDetect to false.

In addition, to authenticate to an HTTP proxy, set ProxyAuthScheme, ProxyUser, and ProxyPassword, in addition to ProxyServer and ProxyPort.

Other Proxies

Set the following properties:

  • To use a proxy-based firewall, set FirewallType, FirewallServer, and FirewallPort.
  • To tunnel the connection, set FirewallType to TUNNEL.
  • To authenticate, specify FirewallUser and FirewallPassword.
  • To authenticate to a SOCKS proxy, additionally set FirewallType to SOCKS5.

Timeout

The value in seconds until the timeout error is thrown, canceling the operation.

Remarks

If Timeout = 0, operations do not time out. The operations run until they complete successfully or until they encounter an error condition.

If Timeout expires and the operation is not yet complete, the Sync App throws an exception.

IBM Cloud Object Storage Connector for CData Sync

UserDefinedViews

A filepath pointing to the JSON configuration file containing your custom views.

Remarks

User Defined Views are defined in a JSON-formatted configuration file called UserDefinedViews.json. The Sync App automatically detects the views specified in this file.

You can also have multiple view definitions and control them using the UserDefinedViews connection property. When you use this property, only the specified views are seen by the Sync App.

This User Defined View configuration file is formatted as follows:

  • Each root element defines the name of a view.
  • Each root element contains a child element, called query, which contains the custom SQL query for the view.

For example:

{
	"MyView": {
		"query": "SELECT * FROM Objects WHERE MyColumn = 'value'"
