The Discard connector can only be used as the last connector in a flow. When it is connected to another connector, any messages passed into the connector are discarded.

Key Capabilities

• Terminal message disposal—discards all received messages with no output or side effects
• Guaranteed end-of-flow enforcement, ensuring messages are not accidentally passed to further connectors
• Lightweight and configuration-free, requiring no setup to drop unwanted messages from a flow

Overview

The Discard connector is a terminal connector that removes any messages it receives, producing no output. Use it as the final step in a flow to intentionally drop messages that require no further processing or routing.

Connector Configuration

Settings Tab

Settings related to the core configuration of the connector.

• Connector Id The static, unique identifier for the connector.
• Connector Type Displays the connector name and a description of what it does.
• Connector Description An optional field to provide a free-form description of the connector and its role in the flow.

Advanced Tab

Other Settings

• Processing Delay The amount of time (in seconds) by which the processing of files placed in the Transactions tab is delayed. This is a legacy setting. Best practice is to use a File connector to manage local file systems instead of this setting.

Logging

• Log Level The verbosity of logs generated by the connector. When you request support, set this to Debug.
• Log Subfolder Scheme Instructs the connector to group files in the Logs folder according to the selected interval. The Weekly option (which is the default) instructs the connector to create a new subfolder each week and store all logs for the week in that folder. Leaving this setting blank tells the connector to save all logs directly in the Logs folder. For connectors that process many transactions, using subfolders helps keep logs organized and improves performance.
• Log Messages Check this to have the log entry for a processed file include a copy of the file itself. If you disable this, you might not be able to download a copy of the file from the Transactions tab.

Miscellaneous

Miscellaneous settings are for specific use cases.

• Other Settings Enables you to configure hidden connector settings in a semicolon-separated list (for example, setting1=value1;setting2=value2). Normal connector use cases and functionality should not require the use of these settings.

Automation Tab

Automation Settings

Settings related to the automatic processing of files by the connector.

• Send A toggle that instructs the connector to automatically send files when they are ready.
• Retry Interval The interval the connector waits before retrying a failed send.
• Max Attempts The number of attempts the connector makes to send the message. Setting this value to 1 instructs the connector to only make the initial send attempt without retrying. The connector waits the duration specified by Retry Interval between each attempt.

Performance

Settings related to the allocation of resources to the connector.

• Max Workers The maximum number of worker threads consumed from the threadpool to process files on this connector. If set, this overrides the default setting on the Performance Settings portion of the Advanced Settings page.
• Max Files The maximum number of files sent by each thread assigned to the connector. If set, this overrides the default setting on the Performance Settings portion of the Advanced Settings page.

Alerts Tab

Settings related to configuring alerts.

Before you can execute Service Level Agreements (SLAs), you need to set up email alerts for notifications. By default, Arc uses the global settings on the Alerts tab. To use other settings for this connector, toggle Override global setting on.

By default, error alerts are enabled, which means that emails are sent whenever there is an error. To turn them off, uncheck the Enable checkbox.

Enter a Subject (mandatory), then optionally enter a comma-separated list of Recipient emails.

SLAs Tab

Settings related to configuring Service Level Agreements (SLAs).

SLAs enable you to configure the volume you expect connectors in your flow to send or receive, and to set the time frame in which you expect that volume to be met. CData Arc sends emails to warn the user when an SLA is not met, and marks the SLA as At Risk, which means that if the SLA is not met soon, it will be marked as Violated. This gives the user an opportunity to step in and determine the reasons the SLA is not being met, and to take appropriate actions. If the SLA is still not met at the end of the at-risk time period, the SLA is marked as violated, and the user is notified again.

To define an SLA, toggle Expected Volume on, then click the Settings tab.

• If your connector has separate send and receive actions, use the radio buttons to specify which direction the SLA pertains to.
• In the Expect at least portion of the window:
  • Set the minimum number of transactions you expect to be processed (the volume)
  • Use the Every fields to specify the time frame
  • Indicate when the SLA should go into effect. If you choose Starting on, complete the date and time fields.
  • Check the boxes for the days of the week that you want the SLA to be in effect. Use the dropdown to choose Everyday if necessary.
• In the Set status to ‘At Risk’ portion of the window, specify when the SLA should be marked as at risk.
  • By default, notifications are not sent until an SLA is in violation. To change that, check Send an ‘At Risk’ notification.

The following example shows an SLA configured for a connector that expects to receive 1000 files every day Monday-Friday. An at-risk notification is sent 1 hour before the end of the time period if the 1000 files have not been received.

Note: You can turn off SLA alerts if necessary. This can be useful during maintenance windows. Click Settings on the navbar, then navigate to Alerts > General Alerts. Click the tablet and pencil icon to edit, and uncheck the SLA Alerts setting.

Transactions Tab

This tab lists all messages associated with the connector. Use the search bar to find specific messages, or click the funnel icon to apply a filter. You can filter by time, message direction, and/or status.
